In this work we analyze different design alternatives for the integration of a gasificationprocess with the oxygen production process, through ITM membranes. We analyze theconventional separation design compared with a novel configuration in a countercurrentarrangement with sweep gas (using the gas permeation module as a mass exchanger). Toassess the oxygen transfer in the permeation modules, they are modeled with Aspen Custom Modeler V8.4 and the different design alternatives are simulated in Aspen Plus V8.6. The economic analysis carried out shows that the counter-current arrangement with a sweep stream has a Total Annualized Cost 13.5% lower than the conventional separation design.
