Title:
METHOD FOR ENRICHING COMBUSTIBLE GAS
Document Type and Number:
WIPO Patent Application WO/2011/118406
Kind Code:
A1
Abstract:
Disclosed is a method for enriching combustible gas which suppresses the deterioration and powderization of an adsorbent without extending a period for a pressure equalization process while enriching a combustible gas. For this, at a time after an adsorption process in a first adsorption tower (U1) connected with a second adsorption tower (U2) through a pressure equalization path (L4) and also after a desorption process in the second adsorption tower (U2), the pressure equalization process is performed while a pressure equalization path on-off valve (V4) provided at the pressure equalization path (L4) is opened.
