Title:
COMBUSTIBLE GAS ENRICHMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/093247
Kind Code:
A1
Abstract:
Provided is a combustible gas enrichment system which enables an improvement in energy saving performance with consideration given to the life of a suction means. Specifically disclosed is a combustible gas enrichment system (S) provided with an adsorption unit (U) into which an adsorbent (a) for selectively adsorbing combustible gas is filled, a source gas feed means (B) which is able to feed source gas containing the combustible gas from the outside into the adsorption unit (U), a suction means (P) which is able to perform treatment for sucking gas from within the adsorption unit (U), and a control means (C) which performs adsorption treatment for feeding the source gas into the adsorption unit (U) to adsorb the combustible gas to the adsorbent (a) and, after the adsorption treatment, desorption treatment for desorbing the combustible gas from the adsorbent (a) by the suction force of the suction means (P) and taking the combustible gas to the outside. The control means (C) operates the suction means (P) such that the suction force of the suction means (P) when the desorption treatment is not performed is smaller than the suction force of the suction means (P) when the desorption treatment is performed.
