Modutek Provides Solvent Delivery Pump Station for Large Pharmaceutical Company

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.

Tips on Selecting an Acid Neutralization System for your Application

Tips on Selecting an Acid Neutralization System for your ApplicationAcid neutralization systems are essential for various industrial processes such as semiconductor fabrication and research facilities that produce acidic effluents. These cannot legally be discharged directly into public sewer systems; instead, they need to first be processed in legally prescribed ways. Altering the pH of acidic waste by-products to legally acceptable pH ranges of between 6 and 9 can be a major challenge, however.

As process engineer or semiconductor facility manager, what do you look for in an acid neutralization system? The best solution is a system that is easy to use, has a low operating cost and complies with all laws and regulations. Managers tend to see waste treatment as an operation that is difficult to administer and control costs in. The use of an effective system that provides automation would be the best option.

Automation frees up resources and lowers costs for businesses. When equipment is properly maintained to manufacturer-recommended specifications, a business can easily manage the process to meet specific criteria.

Acid neutralization systems treat acidic effluents using either continuous-flow processing or batch processing.

Considering a Continuous-flow Neutralization System

Continuous flow neutralization — where a stream of influent is treated while in flow through a pipeline system, prior to discharge — tends to work well in applications where there is a high rate discharge of mild acid or alkali. Continuous flow systems tend to be practical as long as the pH of influents remain stable from one moment to another.

Most systems offer a two-stage handling process; these can be effective for processes that produce moderately acidic effluent. Three-stage processes work well for processes that produce especially polluted effluents.

An automated, continuous-flow neutralization system is designed to provide acid neutralization within the confines of a compact unit, and can process streams as high as 500 gallons per minute.

With microcomputer-controlled monitoring at every stage, there is a high level of reliability to ensure compliance.

Considering a Batch Neutralization System

Acid neutralization systems that handle influent waste acid in batches can be effective in certain applications. Unlike continuous flow systems, batch systems are able to effectively deal with complex, highly acidic influents. Batch systems are suitable in the treatment of processes that cannot be relied upon to produce effluents of stable character. When acidic content tends to change, batches of waste need to be collected and treated separately. Batch neutralization systems also excel in the treatment of influents that are complex in nature — ones that contain heavy metal and fluorides.

These systems come with excellent automation benefits that include:

  • The automation of chlorination and pH adjustment for removal of bacteria.
  • The programming of operational sequences where different reagents and polymer flocculants are fed in.

The Benefits of Choosing an Automated Solution

With an automated acid neutralization system in place, manufacturers are able to get by with a minimal amount oversight to this side of operations. Fully automated from end to end, these systems offer intelligent, sensor-based checks at every point to alert staff of any need for attention, should it arise. Operators can be assured that problems will not go unnoticed.

Choosing the Right Chemical Delivery System for Your ApplicationSemiconductor manufacturers and research labs have extensive chemical handling requirements and need a safe way to supply chemicals to the points where they are used. 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. Facility managers and engineers choosing a chemical delivery system have to evaluate such features and check which suppliers have the expertise to recommend a good fit for their needs.

What Fume Scrubbers Do and the Benefits They Provide

What Acid Fume Scrubbers Do and the Benefits They ProvideManufacturing processes such as semiconductor etching or the cleaning of parts with strong chemical solvents generate exhaust fumes containing the process chemicals in gaseous or droplet form. Such fumes have to be neutralized before they can be released into the atmosphere or into the air inside the manufacturing or research facility. The fumes are harmful to human health and may be corrosive to plant machinery. Companies face fines if they release fumes into the outside atmosphere and may contravene labor standards if the fumes reach the factory floor or lab work areas.

Modutek’s Acid Fume Scrubbers use a wet packed bed to remove acid and base chemical traces in chemical process exhaust fumes. The fumes pass over wet packing material and the chemicals are removed as they come into contact with a neutralizing solution in the beds. Well-designed fume scrubber beds expose the fumes to a large surface area covered in neutralizing solution. The harmful gases dissolve in the solution, are neutralized and are no longer present in the air. A wide range of fume volume handling capability makes the Modutek fume scrubbers suitable for all kinds of manufacturing facilities and university or company research labs.

Custom Designs

Modutek offers a wide range of models to address the various fume scrubbing requirements that customers may have. Air handling capacities range from 500 CFM to 25,000 CFM and each scrubber is designed to meet the customer’s air quality standards.

How Technology Manufacturers Use Chemical Delivery Systems

How-Chemical-Delivery-Systems-are-Used-by-Technology-Manufacturers

Technology manufacturing requires the safe handling of chemicals as well as their delivery in accurate amounts. Corrosive chemicals are used for etching, cleaning and plating materials such as silicon chips, metal parts, solar system components and printed circuit boards. The chemicals have to be stored securely, delivered to the process in precise amounts, and neutralized before disposal. Automated chemical delivery systems reduce waste and operator error while allowing the supply of defined amounts of each chemical with a high degree of precision.

Technology manufacturers use these systems to supply chemicals to wet processing equipment. Acids are used to etch away layers of material on wafers of silicon, printed circuit boards or other substrates. Sections of the layers to be etched are covered in protective material and are not removed by the etching. In this way microscopic structures and conducting paths can be created. The requirements for chemical delivery systems depend on the application of the wet processing equipment and on the chemicals to be used.

The key to supplying effective chemical delivery systems is a flexible approach combined with the ability to develop systems customized to meet the needs of the manufacturer. Companies that manufacture silicon wafers have different requirements from those that manufacture micro-electro-mechanical systems, hard disk drives or solar cells. The cleaning and etching processes of different technology manufacturers use various chemicals and widely varying amounts and process control strategies. Their chemical delivery systems must be resistant to corrosion, be safe to operate, allow the storage of large amounts of chemicals and include flexible software to control distribution. An equipment supplier has to have a good understanding of the processes involved so that they can standardize the parts of the system that can remain the same while developing custom solutions to match the needs of each technology manufacturer.

Modutek specializes in designing and manufacturing systems that provide outstanding performance and reliability with the ability to be highly customizable. The systems incorporate user-friendly features that promote safe and cost-effective operation. In a typical custom application, water use, and the number of defective parts produced is reduced while consistency of results increases.

Modutek’s chemical delivery systems feature all Teflon fluid paths, double containment cabinet construction, leak detection and chemical level sensing. Double wall plumbing and system data logging are available. Chemical storage can be in large tote chemical containers or 55-gallon drums close to the wet process station. Manufacturers that use different chemicals can improve throughput because the Modutek’s systems are designed for quick chemical change.

The software that automates a chemical delivery system is a key factor in the system’s flexibility and Modutek can customize the software to meet the needs of the technology manufacturer. Typically a touch screen shows error messages on start-up and then displays a flow diagram showing the status of key components such as metering pumps, valves and level switches. Since these may be different for particular customized applications, the software must be easily adaptable. All the software for Modutek’s chemical delivery systems is written in house. This means that Modutek has the in house expertise and capability to make changes in the software as needed and can provide excellent technical support without having to rely on exterior sources.

The Modutek chemical delivery systems are suitable for any technology manufacturer application. They are specifically designed for easy customization and provide reliable, cost-effective operation. For additional information about Modutek’s Chemical Delivery Systems or related products call 866-803-1533 or email [email protected]

Benefits of Using Modutek Acid Neutralization Systems

Benefits of Using Modutek Acid Neutralization SystemsAcid neutralization systems adjust the pH value of a process stream in self-contained systems, either continuously or in batches. Effluent monitoring ensures that automatic discharges take place only when the pH values are within set limits. The systems are easy to install with high efficiency and low cost operation. A wide variety of available sizes allows accurate matching to the requirements of particular applications.

Normally acid neutralization systems adjust the pH of a process discharge to within adjustable limits, depending on the application. When discharged into a public sewer, neutralization within a pH range of 6 to 9 is typical. For mildly acidic or alkaline streams with high flow rates and stable characteristics, compact and low cost continuous flow neutralization can be used. When the pH levels fluctuate, inflows are irregular or when the flows are highly acid or alkaline, the use of batch systems is appropriate. These systems neutralize the particular batch and only allow a discharge when the set criteria are reached. A final monitoring chamber for sampling and for recording discharge pH gives operators full control of the effluents.

Flexible Application

Modutek’s acid neutralization systems are available in a wide variety of sizes and configurations. They are designed to suit the requirements of different production facilities and applications, including for semiconductor fabrication, in research centers and in universities. Sizes range from 5 to 500 gpm and installation can be indoor or outdoor, depending on availability of plumbing and electrical connections. The self-contained units are compact and easy to install with an on board reagent tank option. Systems up to 100 gpm are of unitized construction with steel reinforced thermo welded polypropylene while larger systems are skid-mounted.

System Features and Characteristics

Modutek designs its systems with an emphasis on safety and reliability while keeping costs low and saving space. Neutralization systems can operate in fully automatic mode for both acid and alkaline streams. Secondary containment is standard and automatic mode ensures that discharge only occurs when the stream is within permitted pH values. For normal operation, a two-stage system is usually sufficient but three-stage systems are available for especially demanding applications. The control system requires a 120 V AC supply but the mixers and pumps can operate on 120 V or 208 V AC.

The control of the process stream pH is micro-processor based while alarms are handled by a PLC with a touch screen. This combination results in high accuracy and reliability while making it easy to calibrate the sensors and adjust the set points. Neutralizing chemicals are injected into the process with two metering pumps for each stage. Larger systems add pressure control valves.

Alarms include high and low pH in the final monitoring chamber and low level in the reagent storage tanks. There is a liquid sensor in the double containment and all the alarms can be tied into relays for remote signaling at the control panel. Ethernet access for remote signaling is also available and a digital chart recorder monitors and tracks the pH of the process discharge. As a result, there is a continuous record of the pH levels and of alarm conditions during automatic operation.

Overall Benefits

Modutek’s acid neutralization systems offer operators handling chemicals a complete range of neutralization options and system sizes in convenient configurations. The low cost systems are inexpensive to install and reliably ensure that process streams stay within required pH ranges. While operation is fully automatic, comprehensive alarms and monitoring lets the operator check that the system is functioning as intended. If you need more information or would like a quote for your specific requirements contact Modutek by calling 866-803-1533 or sending an email to [email protected]
