摘要
UCG-IGCC发电尾气中含有大量的CO_2和N_2,可将发电尾气注入煤层中,利用CO_2对CH_4的竞争性吸附优势和N_2的分压来强化煤层气的开采,采出的煤层气也可利用IGCC发电机就地转化为便于输送的电力。最后提出了UCG-IGCC发电尾气强化煤层气开采及利用的一种工艺流程及该技术的优点。
UCG-IGCC power generation exhaust contains a lot of CO2 and N2, it can be injected into coal seam to strengthen the mining of coal bed gas for the competitive adsorption advantage of CO2 than CH4 and the partial pressure of N2. The produced coal bed gas can also be converted into electric power which is easier to deliver by IGCC generator. A technological process for strengthening the exploitation and utilization of coal bed gas by UCG-IGCC power generation exhaust is proposed,and the advantages of the technology are also described.
