低浓度煤层气分离提纯的研究进展
Progress of purification technology for low concentration coal-bed methane
摘要
Abstract
This paper reviewed the methods of methane (CH4) separation and purification from coal-bed methane (CBM),including low-temperature distillation,adsorption,membrane separation and gas hydrate separation. By the analysis of the advantages and the disadvantages of these methods,the separation efficiencies under different technical conditions were compared and discussed. Key issues needed to be solved for each method were summarized. For the low-temperature distillation method,de-oxidation is necessarily conducted for the oxygen-containing CBM. The selection of the adsorbent is the key for the adsorption method because the adsorbent determines the economy benefit directly. As for the membrane separation,the separation is affected by the selection of the membrane materials and membrane-making technology. For the hydrated-based CH4 separation,a good additive is crucial to promote the hydrate formation and enhance the CH4 separation efficiency. Finally,the separation of multi-methods or the separation by multi-stage processes is proposed for the future development of CBM separation.关键词
