Document Type and Number:
WIPO Patent Application WO/2018/088811
Kind Code:
A1
Abstract:
The present invention relates to a method for separating olefins from an olefin-containing mixture gas and, more specifically, to a method for separating olefins from an olefin-containing mixture gas, the method comprising an adsorption step, a recovery step, a cleaning step, and a substitution and desorption step, wherein in the cleaning step, adsorbed olefins are cleaned using a desorbent-containing cleaning gas. The present invention can provide a method for separating olefins, wherein high-purity olefins can be obtained by cleaning the olefins in an adsorption tower using a desorbent and economical feasibility can be improved by reducing energy consumption.
