Solvent Processing Using Stainless Steel Stations

Manufacturing processes using volatile solvents have to be specially designed to minimize the risk of explosions or fire. Solvents like acetone or alcohol are used to clean parts, dissolve materials and extract substances.

Safe stainless steel solvent operation depends on specific design measures that reduce the risk of fire or explosion. Modutek provides stainless-steel stations that meet strict safety regulations used in wet bench processing that reduce the risk of ignition of the solvents or their vapors. They have additional features and interlocks in an integrated approach to operator safety. Special safety design measures can include:

• Electrical equipment runs on low voltages and weak currents to reduce the risk from sparks.
• Electric wiring satisfies fire protection standards NFPA 70 and 79.
• Overall station design satisfies hazardous location standards and is certified for Class 1, Division 2 environments.
• The manufacturing process is monitored to detect dangerous conditions such as high temperature.
• Liquid solvent waste is collected in carboys for controlled disposal.
• Safety interlocks eliminate unsafe operation and shut down the process for unsafe conditions.
• Automatic lid operation can seal off chemical containers.
• Operators are trained for safe operation.
• Access controls limit equipment operation to trained personnel.

Modutek's Series SFa and Sa Stainless Steel Stations for solvent processing meet all safety requirements in the applicable regulations. Made of electropolished steel, the stations meet the National Electrical Code Class 1 Division 2 Group D standard for hazardous locations.

The baths feature PVC safety shields, N2 head case purge and an auto lid option. They are designed for operator safety and prioritize safe containment and disposal of volatile solvents. The SFa Series – uses a temperature-controlled re-circulating bath, while the Sa Series is constant temperature.

In addition to the safety measures and temperature control features, the baths have multi-sided heating elements, a 360-degree overflow weir, operating interlocks, process control thermocouples and liquid level sensors. The tanks are available in standard sizes and customized sizes.

Modutek has over 40 years of experience designing wet benches for semiconductor manufacturing. Aa a leading wet bench manufacturer, Modutek works toward advancements to their wet processing equipment, including those with solvent processing stations.

Selecting Chemical Handling Equipment for Solvents and Acids

When chemicals are used in a manufacturing process, chemical handling systems are critical for accurate chemical delivery to the process equipment and the safe disposal of the chemical waste.

Because of the corrosive nature of these solvents and acids, it is crucial that they should be handled effectively and safely. Finding the right chemical handling system for a manufacturing facility is often challenging because the applicable regulation has to be followed and worker safety has to be guaranteed. That's why facilities need a manufacturer with extensive experience in chemical handling equipment and a proven track record that can provide them with the most appropriate system for their specific application.

The right chemical handling equipment ensures safe acquisition, use and disposal of hazardous chemicals used in manufacturing. Essential functions include:

• Delivery – Chemicals have to be delivered to the process equipment in quantities, mixtures, and concentration required. This requires accurate repeatability.
• Collection – Collection of hazardous chemicals takes place in a specially secured cabinet with containment and leak detection capabilities.
• Neutralization – This option is also available if chemical disposal becomes too expensive.

Modutek's chemical handling systems are designed to ensure safe and precise handling of hazardous chemicals. The company also offers neutralization systems which allows some chemicals to be neutralized and disposed directly to your main drain.

Modutek offers a complete line of chemical handling equipment that can also be customized for the specific needs of a manufacturing facility. Their equipment line includes the following:

• Acid neutralization systems – These compact systems add neutralizing chemicals to acid or alkaline waste. They feature either batch or continuous operation or low-operating costs.
• Chemical delivery systems – Chemicals are delivered to the process in exact quantities and at the right times. They help reduce chemical waste and eliminate errors that cause accidental spills.
• Chemical lift stations – These stations pump chemicals directly from the process to the neutralization area.
• Chemical collection systems – Chemicals are collected and stored locally near the process or remotely in large collection tanks.
