MODELING THE TECHNOLOGICAL PROCESS OF METHANOL PRODUCTION

Abstract

Among the technologies of large-scale production of various artificial liquid fuels, one of the most promising is the technology of obtaining methanol from synthesis gas, produced in turn from coal or natural gas. Methanol is a multi-purpose intermediate, on the basis of which various important chemical products can be obtained, as well as an environmentally friendly liquid fuel and solvent. It is convenient for transportation and storage. In recent years, the value of methanol has increased dramatically. Remaining the most important chemical raw material (semi-product), it can help solve most acute and urgent problems of energy, transport, ecology, since methanol can serve as a universal energy carrier, component and raw material for the production of motor fuels, high-octane additives, hydrogen, carbon source for microbiological synthesis of proteins. Interest in methanol is also evident in the formation of long-term energy strategies aimed primarily at solving The paper presents mathematical modeling of the technological process of methanol production. The model of kinetics is calculated according to two main reactions (reactions of interaction of carbon monoxide with hydrogen, carbon dioxide with hydrogen) occurring in kolonne sinteza. Model of dependence of volumetric flow rate and methanol concentration on linear velocity. Model of the dependence of the density of aqueous methanol solutions on concentration and temperature. The influence of regime and technological parameters on the process of obtaining methanol is considered. Based on the analysis of models, the most optimal technological parameters can be selected, which are used to improve the efficiency of the process and the yield of the target product.
