8塔VPSA工艺在低浓度煤层气CH4浓缩富集中的应用OA北大核心
Application of 8-tower VPSA process in low-concentration coalbed methane CH4 concentration and enrichment
为了提高低浓度煤层气的利用率,促进煤矿安全生产与瓦斯治理,基于真空变压吸附(VPSA)工艺的工作原理,提出了 8 塔 1 吸 5 均压(8-1-5)的低浓度煤层气甲烷浓缩富集控制工艺.选用西门子S7-300 型PLC作为下位机控制器,紫金桥V6.5 作为系统控制组态,各吸附塔以 24 步序为 1 个循环周期交替工作.结果表明:8 塔工艺可将低浓度煤层气中的CH4 含量由28%提升至 51.53%,CH4 回收率达到了 96.4%.
In order to improve the utilization rate of low-concentration coalbed methane,promote coal mine safety production and gas control,based on the working principle of vacuum pressure swing adsorption(VPSA)process,a control process of methane con-centration and enrichment for low concentration coalbed methane with 8 towers,1 suction and 5 pressure equalization(8-1-5)is pro-posed.Siemens S7-300 PLC is selected as the lower computer controller,Zijinqiao V6.5 is used as the system control configuration,and each adsorption tower works alternately with 24 steps as a cycle.The results show that the 8-tower process can increase the CH4 content in low-concentration coalbed methane from 28% to 51.53%,and the CH4 recovery rate reaches 96.4% .
