Where is methanol primarily consumed in low-temperature methanol washing, and why?

Gas entrainment； Gas containing alcohol is caused by load fluctuations, unstable tower pressure differences, detachment of the wire mesh demister, or poor treatment efficiency. 2. Waste water entrainment ； Failure to operate the water separation tower in accordance with the specified parameters resulted in unacceptable quality of the wastewater at the bottom of the tower; 3. Leaks, spills, drips, and seeps at the site ； 4. The washing efficiency of the exhaust gas scrubber is unsatisfactory ；
What was said on the 2nd floor is correct; it’s mainly due to the entrainment of CO2 vapor. In our second-phase low-temperature methanol washing process, the methanol consumption is 80% lower than that in the first phase, and this depends largely on the efficiency of the demister in the flash tower
Gas entrainment is most significant in carbon dioxide product gas
1. Under driving conditions, since the temperature of methanol has not dropped, the amount of methanol entrained in the exhaust gas is relatively high at this time； 2. During normal operation: control of the water separation tower, washing efficiency of the exhaust gas scrubber, entrainment of acidic gases, and entrainment of carbon dioxide and hydrogen products ； 3. Leakage during maintenance ；
