Methanol Synthesis Plant

The raw materials for methanol production can be natural gas, coke oven gas, coal, residual oil, naphtha, acetylene tail gas or other waste gas containing hydrogen and carbon monoxide. Since the 1950s, natural gas has gradually become the main raw material for methanol synthesis. At present, more than 90% of the plants in the world use natural gas as the raw material. Because the process of methanol production from natural gas is short, investment is low, production costs are low, and the emissions of three wastes are low, it is a vigorously promoted clean energy.

Technical characteristics

Energy saving and investment saving.

High equipment integration, small on-site workload and short construction period.

The methanol synthesis tower with new by-product medium-pressure steam is adopted to reduce energy consumption.

Adopt energy-saving technologies, such as hydrogen recovery technology, pre-conversion, natural gas saturation technology, combustion air preheating technology, to reduce methanol consumption. Through various measures, the energy consumption per ton of methanol was reduced from 38~40GJ to 29~33GJ.

Process

Technological process

Natural gas is used as raw material to obtain syngas (mainly H2 and CO) through compression, desulfurization, purification and gas making. The syngas is further compressed and then enters the methanol synthesis tower to synthesize methanol under the action of catalyst. After the synthesis of crude methanol, the fusel is removed by pre-rectification, and the finished methanol is obtained by rectification.

Technological process

Natural gas is used as raw material, which is compressed, desulfurized, purified, transformed, purified by hydrogen, and added with nitrogen to produce a certain amount of synthetic gas (mainly composed of H2 and N2). After the syngas is further compressed, it enters the ammonia synthesis tower, where ammonia is synthesized under the action of catalyst, and finally the product ammonia is obtained after cooling.
