Problems with methanol distillation vent emissions
Thread Content
Experts, I need help understanding why a separate balance gas network is required for the vent gas from methanol distillation Why not put it directly into the flare pipeline network?
It is necessary to consider its physicochemical properties, the risks associated with mixing it with other exhaust gases before combustion, as well as the effects of process pressure and temperature, and so on. For reference.
It can be directly vented to the flare, but after the liquid has been recovered, the wash gas can also be directly vented to the flare
The pressure in the pre-tower of the distillation column is relatively low; if it enters the flare header, it will prevent the air from the pre-tower from being discharged when other units are releasing gases
