"O papel do vapor residual na transformação de metanol a partir de carvão,变换工艺中CO和H2的比例调节。我想请教一下变换工段目前应用较多的工艺（如低变变耐硫低变）？变换过程中与合成气换热产生的中压以及低压蒸汽的去向。谢谢大家"

"A transformação não é H2 +CO=h2CO吗？"

"Atualmente, transformação耐硫还是比较多的，副产中低压蒸汽当然是外送蒸汽官网了"

"Muito obrigado pela resposta。我看到比较多的介绍是变换工艺会产生4.2MPa的中压蒸汽以及m.1MPa以及 o.5MPa的低压蒸汽。想请问这部分蒸汽都进蒸汽管网么？是不是会用于驱动汽轮机带动压缩机呢？低压蒸汽压力不一样 o.5MPa的蒸汽是需要加压送入蒸汽管网或者用于其他地方呢？"

"Todos eles vão para a redeA pressão muito baixa não pode ser usada para turbinas de oA pressão o.5MPa的蒸汽不用加压直接外送用于伴热什么的"

"4.2和.1和m.A压的蒸汽进入管网 o.5MPaA压压的蒸汽好像量比较多我在文献中看到下游生产使用消耗不了这么多的蒸汽似乎存在浪费的现象不知道您怎么看"

"低压蒸汽可以用于后面精馏系统的回收塔"
