abstract
The purpose of this paper is to introduce a systematic approach to the design of pervaporation networks for waste minimization applications. The objective of this design strategy is to synthesize a pervaporation network consisting of pervaporation modules, booster pumps, vacuum pumps, heaters, coolers and condensers that can separate a waste stream containing some undesirable component into a lean (retentate) stream which is essentially free from the undesirable compound, and a rich (permeate stream) in which the undesirable compound is concentrated. A structural representation of the problem is first introduced that is rich enough to embed all potential configurations of the system. The problem is then formulated as an optimization program to minimize the total annualized cost of the entire network subject to environmental, technical and economic objectives. The solution of this program yields the optimal network configuration, the number and sizes of pervaporation modules, booster pumps, vacuum pumps, heaters, coolers and condensers that are required to perform the specified separation task. Finally, the applicability of the design procedure is demonstrated via two case studies on the separation of chlorinated hydrocarbons from wastewater streams. 1993.
