Abstract: Aiming at solving the problems existed in a certain coal to methanol plant,a calculation model for the gravity flow piping system of the methanol washing column is established,and the quantitative relationship between the liquid level of the collector tank of B section and the lean methanol operation load is determined.According to the load changes of the methanol washing column before and after the de-bottleneck renovation,the tray hydraulics of the four sections of the column are calculated and the bottleneck is therefore found.An effective renovation scheme is proposed accordingly.After the implementation of the renovation scheme,this coal-to-methanol plant has successfully put into operation and reached a running capacity of 620 000 tons/year.
