In the process, the partial pressure of the C<jats:sub>3<\/jats:sub>\u2010mixture is controlled with nitrogen, which is used as inert gas. With an equimolar feed of C<jats:sub>3<\/jats:sub> diluted to 50% with nitrogen, the column is fed at 5 bar and 423 K, and the product is obtained when the total pressure is lowered to 0.1 bar. After 15\u201320 cycles, the cyclic steady\u2010state condition is achieved, a propylene\u2010enriched stream of 98% mol relative to propylene\/propane mixture, with 3.2% of nitrogen, a recovery of 19% (molar basis), and a productivity of 0.785 mol\/kg\u00b7h is obtained. The experimental work was complemented with numerical simulations, and the effect of different operating parameters on the performance of the VSA was considered.<\/jats:p>","DOI":"10.1002\/aic.690470212","type":"journal-article","created":{"date-parts":[[2004,4,16]],"date-time":"2004-04-16T14:12:36Z","timestamp":1082124756000},"page":"341-357","source":"Crossref","is-referenced-by-count":174,"title":["Propylene\/propane separation by vacuum swing adsorption using 13X zeolite"],"prefix":"10.1002","volume":"47","author":[{"given":"Francisco A.
