摘要
煤层气中的甲烷是一种优质的气态燃料和化工原料,但是我国抽放煤层气中甲烷浓度大多数情况下都很低,严重制约了煤层气的综合利用。变压吸附(PSA)技术以其独特的优势已成为人们关注的煤层气分离提纯的技术。本文采用计算机模拟的方法对模拟的抽放煤层气(CH4-N2混合气体)提浓甲烷的PSA全过程进行了模拟,从理论上较为全面地分析了PSA过程操作参数对甲烷提浓的影响,为煤层气的实际分离过程提供一定的设计依据。
Methane is the main component in coalbed gas, and its concentration can be achieved by pressure swing adsorption （PSA）, which has many advantages over the other separation technologies. In this paper, the PSA process for separation of simulated coalhed gas （CH4/N2 mixture） was simulated. The influence of operation conditions on the separation of methane was analyzed using the calculated results. The results can be applied in the design of coalbed gas separation in practice.
