What determines the minimum gas processing volume (minimum load) for low-temperature methanol washing?
It is limited by the cooling capacity of the system and the minimum load of the tower, with the latter being the most important.
It’s the circulation rate – around 50% recently. When driving with low coolant levels, the circulation rate should also be around 60% when guiding air
Depending on the design load of each tower, the general design range is 60-110% or 70-120%. The typical design for methanol washing is 60-110%.
