Why Chemical Delivery Systems Need Customizing for Your Facility

Posted on by

Why Chemical Delivery Systems Need Customizing for Your FacilityIn any industrial process involving chemicals, careful storage, delivery, and disposal of potentially hazardous substances is essential for both safety and efficiency. The chemicals need to be readily available in the correct amounts wherever required in the process. However, the storage of chemicals in the middle of a production line is unlikely to be practical or safe. This requires chemical delivery systems that can seamlessly fit into a facility without increasing risks or reducing productivity.

There is no single solution for chemical storage and delivery systems for industrial facility designers, and the design and placement of the chemical handling equipment will vary from facility to facility. The way chemicals are used directly impacts the system’s design, and the specific kinds of chemicals involved mean that safety aspects need to be considered case by case.

For example, if solvents are used specific materials with fire suppression features must be incorporated to meet safety requirements.  What’s more, all of this usually will need to fit within the restrictions of the existing building unless a new facility is built from scratch.

Bearing all this in mind, custom chemical delivery systems are the most effective way of solving these common problems, and three key points should be addressed right from the start of the design.

  1. Chemical Storage

Whether your process involves high volumes of a single chemical or mixtures of several different ones, they need to be stored in a way that combines complete safety with easy access. The storage units need to be accessible to receive deliveries from suppliers and be kept in an area where any potential leaks or spills can be contained.  They also need full accessibility for efficient delivery to the production line. Modutek can design chemical delivery systems that access chemical storage units up to 100 yards from their point of use. This keeps dangerous substances in controlled conditions far from their point of use to minimize risks without compromising productivity.

  1. Safe and Efficient Chemical Delivery

In most facilities, there’s much more to chemical delivery than simply pumping fluids from storage to the processing location. The chemicals need to be delivered in the exact quantities the process requires, in the correct sequence, and at the right time intervals.

There will also need to be a mechanism for handling delivery failure without risking damage to the facility or wasting the other materials involved in the process. In addition, the system should keep track of the quantities of each chemical used, streamlining stock management and replenishment. Each of these factors will be different depending on the details of the application, so a chemical delivery system designed by experienced experts is vital.

  1. Safe Chemical Disposal in Line with Regulations

Most chemical processes create waste that is still chemically active and often toxic, corrosive, or dangerous in other ways. Safe collection and disposal procedures are essential to protect the facility’s employees and meet all relevant environmental regulations and legal responsibilities. In most cases, residual chemicals must be neutralized on-site before disposal or collected and securely stored before transportation to a dedicated disposal facility. Depending on the specific chemicals involved, the collection and neutralization process can be hazardous, involving toxic vapors, corrosive liquids, and countless other potential dangers. Again, the choice of chemical-handling equipment used during disposal depends entirely on the range of chemicals involved and the risks they create.

The Bottom Line

If you’re looking for the ideal solution for your facility, Modutek has the in-house expertise, experience, and engineering capability to produce customized chemical delivery systems to meet your specific requirements. Modutek also provides a full range of chemical neutralization, collection, and disposal equipment, to ensure your on-site systems meet regulatory requirements and operate reliably with maximum efficiency and safety.

Designing Chemical Delivery Systems to Meet Facility Requirements

Posted on by

Because semiconductor manufacturing facilities use a variety of chemicals to clean, etch and process silicon wafers, chemical delivery systems are critical for ensuring that operations run smoothly. Chemical handling equipment delivers or collects the required chemicals for the safe disposal of the chemical waste. Effective chemical delivery systems remove concerns about the availability and correct mixture of process chemicals and allow operators to focus on issues directly affecting silicon wafer fabrication, such as wafer cleaning, etch rates, and particle contamination. When chemical delivery systems exactly meet facility requirements, a focus on the fabrication processes lets operators optimize production and helps improve output.

Adapting Receiving and Storage of Chemicals to Facility Requirements

Chemical delivery depends on how many different chemicals a facility requires and the volume of the chemicals used. Chemical characteristics such as toxicity also have to be considered. For facilities using a variety of chemicals in varying quantities, a special area may be needed to centralize reception and storage functions.

For small volumes of chemicals, a standard drum located near the process may be the most convenient. For large volumes, receiving and storing chemical totes monitored with a load cell to track chemical use could be the best solution. For dangerous chemicals, containment of possible leaks and special safety measures may be required to ensure compliance with environmental and safety regulations. A competent manufacturer of chemical delivery and storage systems can evaluate these factors and make corresponding recommendations.

Ensuring Timely and Reliable Delivery of Chemicals to the Process

The key function of chemical delivery systems is to ensure that the required chemicals are provided in precise amounts as needed for the process. Silicon wafer fabrication steps clean and etch wafers with mixtures of chemicals that have to be delivered to process tanks. Each step requires precise quantities of chemicals delivered in sequence and at timed or process-dependent intervals. Each facility has different process steps and different chemical delivery requirements. A well-designed chemical delivery system will reliably provide exactly the right chemical in the specified volume at the correct time.

Collecting and Disposing of Used Chemicals Safely

Once a process step is complete, the chemical mixture that remains is often still chemically active, toxic and dangerous. The wafers will have been removed from the chemical bath and the used chemicals need to be safely treated or collected and disposed. For example, acids used in wafer etching are hazardous for operators, harmful for the environment and even the vapors may be dangerous.

Disposal of chemical waste has to be in accordance with local safety and environmental regulations. The chemical system can either drain the chemical waste and send it to an on-site chemical neutralization system for treatment, or to storage in a chemical collection container. Used chemicals in chemical collection containers can be picked up by service providers that specialize in chemical disposal. In either case, the chemical handling has to be carried out safely while containing any leaks or spills.

Systems That Support Chemical Delivery and Disposal Requirements

Posted on by

Systems that Support Chemical Delivery and Disposal RequirementsWhen corrosive chemicals are used by manufacturers and research centers, they have to be stored safely, delivered to the process in precise quantities and neutralized prior to disposal. Chemical delivery systems that manage the use and disposal of chemicals have to be designed for high reliability and for compliance with local environmental regulations. Even for chemicals that are not hazardous, these systems can reduce waste and improve productivity. The varied requirements for chemical handling systems that fulfill these functions mean that a high degree of customization is necessary. Modutek offers a complete line of chemical handling products that support chemical delivery and disposal with extensive customization.

How Chemical Delivery Systems Improve Manufacturing Facility Performance

Effective chemical delivery systems make sure that chemicals are tracked from reception through storage to use in the manufacturing process. Low storage volume alarms let operators place orders to ensure a continuous supply. Bulk storage can take place in a separate storage area while smaller quantities can be stored close to the process. Sometimes chemicals have to be mixed or different chemicals added to the process at different times. Both storage and delivery to the process can be automated to varying degrees. Double containment and leak detection may be required. Such chemical delivery systems provide the following benefits:

  • Better process flow. Tracking chemical use and making sure there is enough supply lets the manufacturing process run more smoothly with a constant chemical consumption.
  • Higher output quality. Precise dosage and excellent repeatability results in reliable product quality over time.
  • Reduced waste. Chemical tracking, leak detection and reduced operator error mean there is less chemical waste.
  • Improved workplace safety. When operators don’t have to handle chemicals directly, they are less exposed to hazardous substances and the workplace becomes safer.

As a result of these benefits, chemical delivery systems can reduce costs and improve overall manufacturing and research facility performance.

How Chemical Disposal Systems Ensure Safety and Regulatory Compliance

When chemical disposal systems work properly, they ensure that all chemical waste is collected and disposed of safely in accordance with environmental regulations. Chemical disposal requires the use of Department of Transportation (DOT) approved containers. DOT approved containers provide added safety to prevent leaks during handling and transportation.

Modutek offers different chemical collection and disposal systems which include mobile chemical carts as well as larger volume chemical collection systems. Chemical carts (sometimes called chemical pump carts, chemical collection carts or chemical disposal carts) are units that can be easily rolled up to a process station to pump used chemicals into the DOT approved container within the cart. Modutek also provides chemical collection systems from 5 gallon carboy DOT approved containers to larger collection tanks and collection tank farms to support higher volume requirements. These systems incorporate the use of software controls to monitor chemical disposal levels, leak detection and data logging to keep your facility in continuous operation. With Modutek’s chemical collection systems and software interface there is no down time due to the “fill/empty” control system. Since Modutek designs all their Chemical Collection and Disposal Systems in house all the software and equipment is engineered and manufactured to meet a customer’s specific requirements.

Reliable Systems Customized for Volume, Process and Facility

Modutek has the experience and in-house expertise to customize all chemical handling systems for chemical delivery and disposal as needed. Factors such as chemical volumes used, types of chemical processes and facility layout all influence the system design. The degree of automation desired and the local regulatory environment are always different. Chemical delivery and disposal systems have to be adapted to meet these different requirements. Since Modutek builds its own systems, the company can adapt standard designs and automation to satisfy the unique needs of its customers. Contact Modutek for a free consultation to determine the right chemical delivery and disposal equipment that is needed to meet your requirements.

Chemical Delivery Systems Designed to Meet Facility Requirements

Posted on by

Different semiconductor manufacturing facilities or other users of chemicals have varying needs. The chemical delivery requirements of large chip producers differ from those of small fabricators, custom shops or research facilities. Chemical delivery system capacity, equipment layout, the number of different chemicals and the specifications for quality, accuracy and quantity may all vary, depending on the facility and the application. Suppliers of chemical delivery systems need to be able to customize their equipment to satisfy the specific requirements of different facilities. Suppliers who manufacture their own equipment in house are best able to adapt their standard products to the needs of their customers more easily than those using third party manufacturers.

Storage, Delivery and Disposal Are Key System Functions

The operation of chemical delivery systems can be divided into storage, delivery and disposal functions. These functions are impacted by chemical volumes, number of chemicals and facility layout. For operations that need a large volume of chemicals, storage and delivery options are going to be different than for small operations. The space and equipment layout at a facility also determines how the key functions are executed. A competent supplier has to be able to evaluate all the relevant factors and requirements before designing and building the custom system.

For example, for large volumes of chemical usage, storage space for chemical totes and a load cell interface for tracking chemical use are required. If small volumes of chemical are used, storage can fit into small spaces close to the point of use. Similarly, disposal differs according to the volume of waste chemical generated. Waste liquids can be neutralized close to where the waste is generated or the waste liquids can be piped away for remote neutralization and disposal.

How Chemicals Are Used Impacts System Design

A facility that uses large volumes of a few chemicals will need only very simple controls while a production line that spikes with some chemicals and mixes others will require complex controls with high precision. Requirements for repeatability, accuracy and quality control all come into the specifications for the design and configuration of the system. Sometimes manual open loop controls are adequate but for other facilities fast, closed loop automation may be critical. Software, modeling and robotics are expensive and may not be required for some applications but may be necessary for others. The chemical delivery system provided to a facility needs to incorporate each of these specific requirements.

Safe Operation Depends on the Chemicals Used

While operator safety is paramount, the actual safety features required for an installation depend on the chemicals used. Non-hazardous chemicals may not need any special safety measures while highly inflammable solvents may require explosion-proof designs with the relevant National Electrical Code (NEC) and National Fire Protection Association (NFPA) certifications.

Safety measures for hazardous chemicals can include operational strategies to reduce worker exposure. For some applications, a degree of automation up to fully automatic systems can increase safety and reduce operator error. For others, less expensive solutions can include semi-automatic or manual systems with corresponding safety interlocks and automatic shut-down for dangerous conditions. In each case, the specific operating characteristics of the chemical delivery system have to be evaluated and a custom solution has to be designed and installed.

Modutek Can Customize Chemical Delivery Systems

Modutek designs and builds their own equipment down to programming their own software for chemical dosage and for automation. With extensive experience in the field of chemical delivery systems and in house design and manufacturing expertise, Modutek can customize their systems to the extent required.

How Chemical Delivery Systems Are Customized for Specific Applications

Posted on by

Many types of industrial plants and research centers use chemicals in their operations and need systems that can handle these often dangerous substances effectively. The chemical delivery system has to be able to store the chemicals, deliver them to the point of use and handle disposal. Depending on the application, chemical mixing and a degree of automation may also be required. Key characteristics of chemical delivery systems include the following:

  • Reliability. Dependable systems must deliver the right amounts of chemicals as required.
  • Accuracy. Most processes need specific amounts of chemicals at various times. The dosage and timing has to be precise.
  • Efficiency. The system must be easy to operate manually and to program for automatic operation.
  • Reduced Waste. Only the amounts of chemicals and water needed are delivered and material is recycled as much as possible.
  • Repeatability. A process step can be carried out repeatedly and always get the same result.
  • Safety. The system must deliver reduced operator error and reduce potential operator exposure to harmful chemicals.

Designing chemical delivery systems with these characteristics means the systems will have a high degree of customization with regard to many of the system components and functions. A provider will have to custom design and manufacture the equipment to fit the location, the application and any specific customer requirements.

The Volume of Chemicals Needed Impacts the System

Some processes only need small amounts of chemicals for spiking solutions or for processing small mixtures while other applications require bulk chemical supply. For spiking, delivering precise dosages is critical while for bulk chemical use receiving and storage are important. Small chemical volumes can be stored wherever there is a small space available but large volumes may need space for large chemical totes along with a load cell interface to keep track of chemical use. Each application depends on site layout and available room for the chemical delivery equipment. Systems have to be customized to fit into the available space.

How Chemicals Are Used Influences Customized Controls

Bulk supply of a single substance needs relatively simple controls but mixing and blending several chemicals needs software and relatively complicated systems. The toxicity and aggressiveness of the chemicals impacts the peripheral physical systems to ensure against leaks, spills and the possible exposure of employees. Each chemical delivery system has unique requirements for functions such as mixing, acidity, etching capability and chemical disposal. Customized controls can accomplish these tasks as long as the basic system has the necessary flexibility and the supplier has the expertise and experience to customize the controls.

Facility Layout Affects System Design

Often an ideal layout situates a small storage container near the process where the chemical is being used. In other systems, it may make sense to bring the chemical from remote storage to the process and pipe the used products away for disposal. While the chemical delivery part of the system is clear, the placement of the system components depends on available space and detailed operational practices. In each case, the physical details of the system have to be adjusted for the site and site-specific operations.

Modutek Can Meet Customization Requirements

With extensive expertise in the field of chemical delivery systems, Modutek has the capability to adapt these systems as needed by their customers. Because the company designs and manufactures its own equipment, it can make changes and adjustments to satisfy specific requirements. Customers can take advantage of Modutek’s in house design and production capabilities to get exactly the systems they need. The resulting customized chemical delivery systems are safe and of the highest quality.

How Chemical Delivery Systems Are Designed to Meet Customer Requirements

Posted on by

how-chemical-delivery-systems-are-designed-to-meet-customer-requirements2Many industrial activities require the supply of a variety of chemicals for their manufacturing or production processes. Because the industrial process may include special procedures and the use of specific chemicals, chemical delivery systems often have to be custom-designed to exactly meet the needs of a facility. Typical custom requirements deal with the quantities of chemicals required, how often chemicals have to be changed, how accurate the delivery or the mix has to be and the repeatability of a specific process. Safe handling is an important issue when the chemicals delivered are hazardous, as is safe neutralization and safe disposal. Customized systems can address each of these issues and ensure that the critical requirements are satisfied while leaving out unimportant features for a cost-effective solution.

Delivery Volumes

The quantities of chemicals used greatly impacts the design of the chemical delivery system. Large totes remote from the process can continuously deliver large volumes over extended periods while local drums and tanks can deliver smaller volumes but can be changed when the process requires a different chemical or when a new production process is started. In each case, load or level sensing has to be available so production personnel can plan the required chemical delivery. Software allows operating personnel to predict flows and requirements so adequate supplies are available.

Precision and Repeatability

Different industrial processes have different requirements for precision. For example, research projects often have to record exactly what chemicals were used and their precise quantity. Some semiconductor manufacturing processes also require high precision but others don’t. Precision is linked to repeatability. If a process has to run exactly the same way each time, the level of precision for chemical delivery has to be the same for each run.

Custom design can guarantee that the levels of precision and repeatability required for a process can be achieved, but such features are expensive. Customization means critical requirements are met but if high precision is not required, costs are reduced to cover what is essential for the process.

Safe Handling and Disposal

Customization is especially important for safety because each chemical has its own hazards and each process presents different dangers. Customized chemical delivery systems provide an additional level of safety to employees in the handling the chemicals and operating the delivery systems for specialized applications. Custom designs look at measures such as double-walled containment, corrosion-resistant fluid paths and leak detection for safe handling. Neutralization and disposal requires a customized approach due to the different ways chemicals are used but also because of the different regulations for safe chemical disposal.

Modutek Provides Solvent Delivery Pump Station for Large Pharmaceutical Company

Posted on by

Modutek Provides Solvent Delivery Pump Station for Large Pharmaceutical CompanyWith over 35 years of experience in the semiconductor manufacturing industry, Modutek has the expertise to handle large projects and challenging applications. The most recent example is a solvent delivery pump supply for a large pharmaceutical company. Nine solvent pump cabinets are required to transfer solvents to centrally located distribution stations. The custom-built cabinets are subject to tight specifications and rigorous compliance with applicable standards.

Project Details

Modutek will supply nine solvent pumping cabinets, each containing two pneumatically operated pumps. The pumps will have pulse dampers and will be fitted with air-actuated ball valves on the inlets and discharge outlets of each pump. Pilot valves will control the supply of clean, dry air (CDA). A series of valves and monitoring systems controls and supervises the transfer of solvents to distribution points close to the process.

Each cabinet will have an ultrasonic leak detector housed in a one-inch pipe “T” at the lowest point in the cabinet. A drain On/Off selector switch will be mounted near the drain port on the outside of the cabinet, and a 4-20 ma pressure transmitter will be mounted on the outside of each cabinet so the local display can be read easily.

Pump Cabinet Operation

The pumps will be controlled by a Programmable Logic Controller (PLC) and will deliver up to four gallons per minute. Solvents handled include acetone, methanol, ethyl acetate, heptane, isopropyl acetate and methyl tert-butyl ether. The system is rated up to 200 degrees Fahrenheit, and the passivation of the stainless steel parts is per ASTM standards. The pressure drop can be controlled through the PLC and the installation must be FDA compliant.

When a request for a pump is received, the drain valve On function is disabled and the pilot valve supplying CDA to the pump opens. The pump inlet and discharge ball valves open allowing solvent to flow past the pressure transmitter to the process. If a leak is detected in the pipe “T,” the pilot valve and the corresponding ball valves close, stopping transfer of the solvent.

When the drain function is switched On, the pilot valves and pump inlet and discharge ball valves are disabled. The pneumatically operated drain valve opens and the solvent drains into a collection container outside the cabinets. Once draining is completed, the operator can close the drain valve and resume normal operation of the pumps.

During normal operation of one of the pumps, the 24 V DC 4-20 ma pressure transmitter displays pressure in the line from the pump to the process. The pressure range is 1 to 150 psi. The pressure reading is displayed on a local LCD display and is available for remote indication and for HMI or SCADA systems.

Key factors for choosing chemical delivery systems are the storage options that are available, the system performance in terms of precision and reliability and the software that can be used to ensure safe and accurate operation.

The chemical delivery systems have to be able to receive the chemicals in bulk, store them safely and conveniently, supply them to the point of use in the required quantities, neutralize them as needed and dispose of them appropriately. Custom configurations, fast chemical change and control options may also be important. Suppliers have to be able to evaluate customer needs and make recommendations based on their experience with chemical delivery systems.

Chemical Delivery System Features

An ideal chemical delivery system improves facility or manufacturing line performance by increasing throughput and producing better quality output. It accomplishes this by reducing manual interventions that can slow down the process and introduce errors. When chemicals are supplied to the point of use exactly as they are needed and with the exact composition required by the process, the facility can operate at optimal efficiency.

A key component of a chemical delivery system is chemical storage. Storage space near the process is often limited but adequate storage to avoid frequent container changes is needed. Ideally the chemical delivery system can continue to operate with integrated storage while a main storage container is being changed.

The mixing and delivery of chemicals to the point of use has to be safe, precise and reliable. Software can calculate the precise amounts needed while monitoring sensors can show chemical paths, levels and other process variables. Extensive and flexible control configurations let customers choose exactly how the chemical delivery system will operate. High quality materials ensure reliable operation and long-term safety.
