In 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.
- 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.
- 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.
- 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.

When wet bench processes use acids to clean, strip, and etch silicon wafers, their exhaust air contains acid mist. This air can’t be released into the workspace because it can harm employees and corrode equipment. Acid fume scrubbers remove acid mist from the exhaust air. They neutralize the acid exhaust and deliver clean air that is safe to release into the outside environment. Modutek’s acid fume scrubbers can remove up to 99 percent of acid mist and are easy to operate. They are available in a wide range of capacities and can be integrated into the wet bench processing line.
Because wet processing of silicon wafers uses different types of chemicals, semiconductor manufacturing facilities need 
When industrial processes such as semiconductor manufacturing use chemicals, the chemical waste needs to be treated before disposal. Chemical waste treatment can be handled on-site with an acid neutralization system or companies can use outside service providers to pick up the waste and properly dispose of it.
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. 
When high-volume chemical delivery systems are not needed because of small production volumes, chemical collection carts can provide safe chemical handling. Also known as chemical delivery carts or chemical pump carts depending on their role, these 
When the right acid neutralization system is chosen, it can automatically add the required neutralizing chemicals to acid waste left over after a semiconductor manufacturing process step. Ideally such a system should use the least amount of chemicals while ensuring adequate neutralization of waste to comply with environmental standards. The system has to have enough capacity to handle the waste chemical flow and it must operate reliably, protecting against spills and documenting chemical use and discharge. With overall environmental standards tightening and local regulations becoming more stringent, semiconductor manufacturers need 
When semiconductor manufacturing process steps include etching or cleaning with acids, the process station exhaust can be harmful. Acid droplets in the discharge air can create health risks for workers and can corrode equipment. Worker safety standards and more stringent environmental regulations may set limits on the permissible acid droplet concentration.
Chemical handling equipment is an important part of a semiconductor manufacturing operation because the aggressive chemicals used in etching and cleaning semiconductor wafers have to be stored, delivered to the process, and disposed of safely. 
critical for accurate chemical delivery to the process equipment and the safe disposal of the chemical waste. Effective chemical handling systems are especially important for solvents and acids because of the corrosive nature and the dangers of unsafe handling of these chemicals. Finding the right chemical handling system for a manufacturing facility is often challenging because the applicable regulations have to be followed and worker safety has to be guaranteed.
