During this Phase I program, the overall feasibility of using membranes to separate organic vapors from effluent air streams has been demonstrated. High-performance, ultrathin composite membranes have been prepared and incorporated into small (one to ten square feet) spiral wound membrane modules. These modules have been evaluated on a series of organic solvent-air mixtures with good results. Typical solvent fluxes with silicone rubber membranes were 2 to 10 litres/m/sup 2/day. An economic analysis of the process based on these fluxes and using reasonable values for the costs of the membrane modules and pump and system components shows that a process using these membranes would be economical with a number of effluent air streams. Process payback times vary from four to ten months, depending on the specific feed stream and operating conditions. Particularly suitable feed streams are those containing 0.5 to 2% of high value solvents that can be reused in the plant producing the stream. 25 figs., 8 tabs.
