Modelling and Simulation of Methanol Production and Conversion into Various Chemical Intermediates and Products

摘要

The present work is focused on process modeling and simulation of methanol production and conversion into various chemical intermediates and final products.Methanol synthesis is achieved by chemical reaction between CO2 and H2,this method being considered an important method for carbon dioxide valorization.The main advantages of this route are the reduction of greenhouse gas emissions and production of one valuable chemical,methanol.A productivity of 500 kmols/h of methanol was set in the present study.Methanol is furthermore converted into useful intermediates and products such as:1)acetic acid,2)dimethyl carbonate(DMC),3)formalin 4)dimethyl ether(DME)5)biodiesel and 6)methyl tert-butil ether(MTBE).The proposed design models were validated using data from the scientific literature.Purities higher than 99% for methanol and methanol derived products were achieved in all cases.The designs under investigation are compared from technical and environmental point of view leading to the conclusion that biodiesel and MTBE productions are the most convenient routes for methanol valorization.
