Propylene/propane separation by vacuum swing adsorption using 13X zeolite

Silva, Francisco A. Da, Rodrigues, Alírio E.·2001·AIChE Journal

Abstract

A vacuum swing adsorption process using 13X zeolite pellets with five steps was designed to split an equimolar mixture of propylene/propane: pressurization with feed; high‐pressure feed; high‐pressure purge with product; cocurrent blowdown; and counter‐current vacuum blowdown, where the enriched propylene product is withdrawn. In the process, the partial pressure of the C 3‐mixture is controlled with nitrogen, which is used as inert gas. With an equimolar feed of C 3 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 15–20 cycles, the cyclic steady‐state condition is achieved, a propylene‐enriched 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·h 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.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
