Description:CFCs emitted as purge streams from large industrial refrigerators are a considerable environmental problem and an economic loss. Membrane vapor recovery systems are able to treat the-se streams. In the Phase I program, existing membranes were fabricated into high-pressure modules and evaluated with a prototype treatment system. The system was able to recover 99% of the CFC vapors contained in the airstream for reuse in the refrigerator. The system performs better and has a lower cost than alternative processes.
In the Phase II program, Membrane Technology Re- search, Inc., proposes to completely demonstrate the tech- nology by performing a range of parametric studies on pilot recovery systems and performing reliability studies over six months of continuous operation.
