【摘要】：以城市固體垃圾為原料,O_2、水蒸氣為氣化介質(zhì),運(yùn)用Aspen Plus模擬軟件對垃圾氣化制合成天然氣過程進(jìn)行模擬,考察O_2當(dāng)量比(ER)、蒸汽進(jìn)料與干燥垃圾質(zhì)量比(m(S)/m(MSW))、甲烷化溫度和甲烷化壓力對合成天然氣CH_4摩爾分?jǐn)?shù)、低位發(fā)熱量和能量轉(zhuǎn)換率的影響。結(jié)果表明,降低ER、m(S)/m(MSW)和甲烷化溫度及增加壓力,有利于提高合成天然氣CH_4摩爾分?jǐn)?shù)、低位發(fā)熱量和能量轉(zhuǎn)換率。當(dāng)ER為0.35、m(S)/m(MSW)為0.5、甲烷化溫度和壓力分別為250℃和0.5 MPa時(shí),所得合成天然氣滿足GB 17820-2012《天然氣》規(guī)定的二類天然氣質(zhì)量要求。
[Abstract]:Using solid waste as raw material and steam as gasification medium, the process of gasification of municipal solid waste to synthetic natural gas was simulated by Aspen Plus software. The effects of O _ 2 equivalent ratio, steam feed / dry waste mass ratio, methanation temperature and methanation pressure on CH_4 mole fraction, low calorific value and energy conversion rate of synthetic natural gas were investigated. Lowering the temperature and increasing the pressure of methanation is beneficial to increase the CH_4 mole fraction, low calorific value and energy conversion rate of synthetic natural gas. When ER is 0.35 mSU / mMSW) 0.5, the methanation temperature and pressure are 250 鈩，
