变换冷凝液温度对粗合成气汽气比的影响及解决方案

摘要

The influence to coal slurry gasification crude syngas Steam/Gas ratio of condensate temperature from co-shift unit was studied by a kind of simple ASPEN PLUS model. And the way to increasing condensate temperature was studied by heat duty analyzing of co shift unit. The results show that crude syngas Steam/Gas ratio could be enhanced by increasing condensate temperature from co-shift unit. And waste heat after 1#co-shifter could be utilized as heat resource.%采用了一种简易的ASPEN PLUS模型，研究了变换冷凝液温度对水煤浆气化粗合成气产品汽气比的影响，通过后续变换工序的热负荷分析论述了提高变换冷凝液的方法。结果表明，提高变换冷凝液温度可以起到提高粗合成气汽气比作用，并且可以利用一段变换后工艺气的余热作为升温热源。
