Evaluate and validate the design of a solvent capture system to handle storage tank venting during normal in-breathing and out-breathing operations at a foam product manufacturing plant.
FOAM MANUFACTURER CHEMICAL STORAGE VENT SYSTEM TECHNICAL EVALUATION
The client manufactures foam products at a southeastern U.S. facility. This facility currently receives toluene diisocyanate (TDI) in tank trucks and performs a pressure-assisted pump offloading procedure whereby the material is transferred into a bulk material tank farm. TDI is then transferred to the process. The client wished to purchase activated carbon canisters and have some piping systems fabricated to support plans to capture the displaced TDI vapors generated during tank transfer operations.
Process Engineering Associates, LLC (PROCESS) was contracted by the client to perform a technical evaluation on the TDI storage, transfer, and vapor collection system components to help ensure all components are properly designed, sized, and rated to handle the conditions of the modified process. After the initial tank rating, the top portion of the tank was rated too low and had to be modified to be able to accommodate the pressure drop through the process vent during normal in-breathing and out-breathing operations.
Process continued to assist the client from a process engineering standpoint after the tank modifications were completed.
