Low-temperature methanol wash heat regeneration tower Methanol-water separation tower
Thread Content
Low-temperature methanol washing, methanol-water separation tower; the methanol vapor at the top of this tower goes to the thermal regeneration tower. Why is there a pipeline that leads to the bottom of the hot zone in the thermal regeneration tower? I would appreciate it if experienced colleagues could explain this to me
Where do the pipelines at the bottom of the regeneration tower go? Is it put into use during normal production?
Due to the different design approach, the diagram shows pipelines with a diameter of 2 inches; it seems that methanol is drained from the lowest points and sent to the waste methanol tank.
Uh, why does it look like it’s our company’s image? Classmate, this is used for maintenance and sewage discharge
If there is sewage discharge, why is a check valve needed?
It should be in use; it doesn’t have a shut-off valve, only a check valve
I checked the drawings for both projects, and this design was not present in either. Pay attention to this issue.
I think it is also possible that the pipeline at the bottom of the heat removal and regeneration tower will be put into use only when a high water content in the lean methanol is detected, or when there is a leak in the water cooler, as well as when the water content in the methanol at the top of the methanol-water distillation tower is high
That pipeline has only one check valve
