What are the reasons for the poor absorption efficiency of the scrubber tower? How to handle it? Reasons: Low temperature of the lean liquid, low circulation volume of the lean liquid, dirty solution with sedimentation, poor thermal regeneration of methanol, unsatisfactory degree of leanness, high water content in methanol, low system pressure, excessively high inlet gas temperature, too fast gas flow rate, deformed or uneven tray plates, damaged internal components of the tower. Solutions: Lower the temperature of the lean liquid, increase the circulation volume of methanol, improve the filtration efficiency of methanol, enhance the effectiveness of thermal regeneration, improve the separation of water from methanol, adjust the system pressure appropriately, lower the inlet gas temperature and flow rate, shut down the system for maintenance, adjust the tray plates, and replace the internal components of the tower.

Solution: Lower the temperature of the lean liquid and increase the circulation of methanol
The temperature of the lean liquid is low, the circulation volume of the lean liquid is small; the solution is dirty and contains sediment, methanol thermal regeneration is inadequate, the degree of leanness is not up to standard, the methanol contains high levels of water, system pressure is low, the inlet gas temperature is too high, the gas flow rate is too fast, the tray plates are deformed or uneven, and the internal components of the tower are damaged.
