摘要
利用Aspen Plus模拟软件对焦炉煤气制甲烷工艺进行了流程模拟。分析了甲烷化反应压力、过热蒸汽与反应进料气质量比对反应器出口温度和甲烷产量的影响。结果显示,当反应压力在10×103kPa^30×103kPa时,可调控两个反应器出口温度范围均为0℃~50℃,甲烷产量变化很大;当过热蒸汽与反应进料气质量比在0.05~0.40时,可调控第一、二级反应器出口温度范围分别为0℃~50℃和0℃~25℃,甲烷产量变化不大。
The COG （coke oven gas） to methane process was simulated with ASPEN PLUS. The impact caused by methanation reaction pressure, superheated steam and reaction feed gas mass ratio on the reactor outlet temperature and methane output were developed by the analysis tool in ASPEN PLUS. The result showed that when the reaction pressure changed in the range between 10xl03 kPa-30xl03 kPa the outlet temperature of the two reactors could be controlled be- tween 0 ~C and 50 ~C, and the methane yield changed sharply. While the mass ratio between the superheated steam and the reaction feed gas was in the range between 0.05 and 0.40, the outlet temperature of the first and second reactors could be controlled between 0-50 ~C and 0-25 ~C respectively. By contrast, there was little change in the methane yield.
