Technologies for methanol production from synthesis gas are analyzed. Their main advantages and disadvantages are determined, and a new methanol synthesis technology without feed circulation is proposed, which, in particular, is also applicable at a significant nitrogen content of the synthesis gas feed. On the basis of the results of laboratory and bench tests of the new process, mathematical models of a catalyst grain and a catalytic reactor and a kinetic model of methanol synthesis are constructed and their parameters are estimated. It is shown that the models fit experimental data. A three-reactor methanol synthesis unit providing 75-80% conversion of the synthesis gas feed is calculated. The crude methanol obtained has a high content of the desired product of 94-99 wt %. It is demonstrated that this process is characterized by much lower feed and energy consumption.
