摘要

The processes for producing methanol from syngas and syngas from natural gas are simulated. A kinetic model for the reaction of steam-carbon dioxide reforming of methane that is in good agreement with the experimental data obtained for the ranges of gas hourly gas velocities of 1000 to 10000 h~(-1) temperatures of 700 to 850°C, and pressures of 0.4 to 2.0 MPa is developed. A power- and resource-saving process flowsheet for the production of methanol at a variable pressure in the catalytic reactors is proposed. Methods of intensifying an industrial methanol synthesis process with an end-product output of 60000 tons per year are developed. It is shown that when the carbon dioxide formed in the reaction of steam reforming of methane is recycled to the feed, the methanol output can be increased up to 72000 tons per year.
