摘要以城市围体垃极为原料,O2、水蒸气为气化介质,运用AspenPlus模拟软件对垃圾气化制合成天然气过程进行模拟,考察O:当量比(ER)、蒸汽进料与干燥垃圾质量比(m(S)/m(MSW))、甲烷化温度和甲烷化压力对合成天然气CH摩尔分数、低位发热量和能量转换率的影响。结果表明,降低 ER、m(S)/m(MSW)和甲烷化温度及增加压力,有利于提高合成天然气CH,摩尔分数、低位发热量和能量转换率。当ER为0.35、m(S)/m(MSW)为0.5、甲烷化温度和压力分别为250C和0.5MPa时,所得合成天然气满足GB17820一2012《天然气》规定的二类天然气质量要求。

Abstract: A process was designed and simulated by Aspen Plus for the production of synthetic natural gas (SVG) from municipal solid waste (MSW) gasification, with Oz and steam as gasifying agents.The influences of O, to MSW equivalent ratio (ER), steam-to-MSW mass ratio (m(S)/m(MSW)), methanation temperature and methanation pressure on the CH, concentration in SNG, lower heating value (LHV) of SNG and energy conversion efficiency were analyzed in detail. With the increase of ER, m(S)/m(MSW) and methanation temperature, the CH, concentration, LHV of SNG and energy conversion efficiency were decreasing, respectively. And a higher methanation pressure was in favor of CH, content, LHV and energy conversion efficiency. When the ER, m(S)/m(MSW), methanation temperature and pressure were 0. 35, 0. 5, 250 C and o. 5 MPa separately, the quality of produced SNG could meet the requirements of two-class NG of GB 178202012.
