Abstract:
1. A reaction process, comprising: (a) providing a reaction zone; (b) introducing a first reaction stream comprising a reagent A and a second reaction stream comprising a reagent B into the reaction zone; (c) reacting reagents A and B, thereby forming a reaction product in a reaction mixture; (d) withdrawing at least a portion of the reaction mixture from the reaction zone; (e) removing at least a portion of the reaction product from the withdrawn portion of the reaction mixture to form a reaction product stream and a non-product stream containing unreacted reagent A and at least one inert component C; (f) providing a membrane having a feed side and a permeate side, and being selectively permeable to reagent A over component C; (g) passing at least a portion of the non-product stream across the feed side; (h) passing a stream containing reagent B as a sweep stream across the permeate side; (i) withdrawing from the feed side a vent stream depleted in reagent A compared with the non-product stream; (j) withdrawing from the permeate side a permeate stream comprising reagent A and reagent B; (k) recirculating at least a portion of the permeate stream to the reaction zone as at least part of the second reaction stream.
