Aiming the reason that high methanol consumption in methanol syngas rectisol device which was caused because device leakage，wastewater send outside and entrainment in gas phase，adopted countermeasures such as strengthen monitoring，strictly control index，technical reforming and adjusting operation，the consumption of methanol reduced significantly.And analyzed the reason of the problems appeared in methanol water tower production such as flooding，dirty of tray，higher temperature of upper than lower of sensitive plate，lower temperature of tower kettle than upper part，and higher temperature of sensitive plat.These problems were analyzed and some corresponding countermeasures were put forward so as to guarantee the normal production.
