摘要
本文提出了一个新型的焦炭和甲醇/动力多联产系统,新系统在焦炉子系统中采用煤炭燃烧替代焦炉煤气燃烧;在合成气制备过程采用焦炉煤气与气化煤气共制合成气,取消了重整反应和变换反应;在合成单元中采用了部分未反应气再循环方式。新型联产系统具有较高的热力性能,系统节能率高达22%。对新系统的(火用)分析结果表明:采用煤炭燃烧替代焦炉煤气燃烧,取消重整单元,以及合成煤气与焦炉煤气共制合成气是系统性能提升的关键所在。总之,新系统进一步拓展了煤基多联产,将为洁净煤技术指引一个新的方向。
A novel polygeneration system was integrated in this paper,which co-generates coke, methanol and power,based on coal gas produced by a gasifier and coke oven gas(COG).In conventional coke-making processes,the COG with high quality is burned directly to provide coking heat.However, in coke-making processes of the new system,we burned Coal with low quality rather than COG. According to the whole system analyses,and the character of Coal gas rich in CO and COG rich in H_2,we combined these two kinds of gases t...
