On Application of Computer Simulation Technology in Methanol Synthesis in the Coal Chemical Industry

Abstract

In this paper, we build a one-dimensional pseudo-homogenous mathematical model for the interpolate heat- exchange synthesis reactor in the methanol synthesis process in the coal chemical industry and embed Aspen Plus to conduct computer process simulation. The simulation results are well consistent with the measured values. We use this model to analyze the effects of inlet temperature, operating pressure and feed rate on the methanol concentration at the outlet of the reactor and at the same time analyze the effects of catalyst in different periods on the yield distribution of coarse methanol. The simulation results show that the operating pressure should be properly increased and the inlet flow should be properly controlled in the production process to ensure methanol yield.
