| Abstract: | A 2-D mathematical model of pressure swing adsorption(PSA) process in an adsorber for coal-mine ventilation air separation was established.A methane separating and enriching process from coal-mine ventilation air using active carbon pellets was numerically studied.The detailed distributions of gas velocity,gas component and adsorbed gas concentration in the bed were obtained and analyzed.The optimization for recovering time was studied.The effects of feed gas concentration on methane separation and enrichment were also researched. |
