Research On Adsorption-Liquefaction Processes Of Coalbed Methane With High Nitrogen Content

Currently, our country boasts its abundant coalbed gas resources, which can be converted to 45 billion tons of standard coal. The development and applications of this alternative clean and premium energy resource will also contribute to the promotion of coal mine safety as well as the lowering of green house gases emissions. The primary obstacle faced by coalbed methane utilization is the low production of single coalbed mine. At the same time, the production sites of coalbed methane are usually far from gas pipe network, and the gas quality variation also make it impossible to inlet the gas into the pipeline, even though is the sites are near the pipe network. The adoption of liquefaction is an effective method to transport coalbed methane from production site to the customers.Coalbed methane itself may contain larger amount of nitrogen compared with natural gas. Nitrogen may also be added into coalbed methane during...
