Combined operation of low-temperature methanol washing
Thread Content
If the design flow rate of the lean methanol pump in low-temperature methanol washing is 160 M3/h and the maximum flow rate is 180 M3/h, what is the circulation volume of the lean methanol pump during water-cooled operation? How is the amount determined?
During water-methanol combined transportation, the circulation rate of the lean methanol pump is 130 M3/H. The amount is calculated based on specific gravity. In water interconnection, operating at maximum flow rate is required to achieve the desired effect.
It’s mainly because water has a higher density than methanol~! During water circulation, a certain margin should be left for the pump to prevent excessive power consumption caused by the pump trying to pump water, which could lead to motor damage~! If the methanol pump operates at a normal level of 160, the water circulation output will be around 120 to 130 units of flow rate
