Process for synthesizing methanol from coke oven gas

Abstract

A process for synthesizing methanol from coke oven gas without air separator and autothermal conversion is characterized by that the coke oven gas is physically mixed with one or more gas sources with low hydrogen / carbon ratio, that is, H2-CO2 / CO+CO2=2.01-2.15. Its advantages are simple process, low cost and high output.

Description

Technical field [0001] The invention relates to a method for synthesizing methanol from coke oven gas. Background technique [0002] my country is rich in coal resources, and the rapid development of mechanical coke produces a large amount of coke oven gas. Enterprises with conditions can recycle and purify it to meet the gas consumption of residents. Some enterprises have designed gas power generation devices, while some enterprises release the gas in vain. , not only causes waste but also pollutes the environment. For this reason, people use modern technology to combine the characteristics of coke oven gas to organically combine the traditional coking industry with the chemical industry to produce basic chemical raw materials such as methanol and dimethyl ether. Currently, coke oven gas is used To produce methanol, the coke oven gas from the coking plant is usually put into the coke oven gas compressor for pressurization, and then enters the desulfurization device for desulf...

Problems solved by technology

Since the autothermal conversion in the current production process requires an air separation unit, and the investment in the autothermal reformer is large, the process is complicated and the cost is high. At the same time, because the hydrogen-carbon ratio in the prepared raw material gas is about 2.8, there is excess hydrogen and the conversion rate is low.
