Problems solved by technology

[0002] At present, there are many raw materials for the production of methanol, such as natural gas, coke oven gas, naphtha, heavy oil, coal or coke, etc. In most steel coke co-production enterprises, the coke oven gas produced in the coking process is used to produce methanol. It is a gas with high hydrogen content, so that in the process of producing methanol, the ratio of hydrogen to carbon in the synthesis gas produced afte

Embodiment 1

[0102] Taking coke oven gas and converter gas produced by steel coke co-production enterprises as raw materials, at a certain moment, the composition of raw materials is:

[0103] The content of each component in coke oven gas is:

[0104] project

[0105] The content of each component in converter gas is:

[0106] project

[0107] The composition and impurities of converter gas before and after purification are as follows:

[0108] project

[0109] Before adding converter gas, the composition of coke oven gas and converted synthesis gas is:

[0110] project

[0111] At this moment, the online analysis of the proportion of the effective components of the synthesis gas required to convert the coke oven gas into methanol is as follows: H 2 is 71.42%; CO is 11.42%; CO 2 was 11.86%. Before the synthesis gas enters the synthesis gas compressor, the temperature is controlled below 40°C, and the pressure is about 2.0Mpa. At this time, the h...

Abstract

The embodiment of the invention discloses a method for producing methanol, which comprises the following steps of: purifying coal converter gas; mixing the purified converter gas and coke oven gas to obtain mixed gas; and performing reaction on the mixed gas to obtain the methanol. In the method and the equipment for producing the methanol, byproduct gas generated in the steelmaking process, namely the converter gas is purified and mixed with the coke oven gas in the coking process according to a proper ratio, so that a carbon/hydrogen ratio in the synthetic gas generated through desulfurization and conversion of the mixed gas meets the requirement of a theoretical value, the utilization rate of useful elements in the raw materials is improved, the production efficiency is improved, the pollution of waste gas to the environment is reduced, the production cost is reduced and the economic benefit is improved.

Description

technical field [0001] The invention relates to the field of chemical industry, more specifically, to a method and equipment for producing methanol. Background technique [0002] At present, there are many raw materials for the production of methanol, such as natural gas, coke oven gas, naphtha, heavy oil, coal or coke, etc. In most steel coke co-production enterprises, the coke oven gas produced in the coking process is used to produce methanol. It is a gas with high hydrogen content, so that in the process of producing methanol, the ratio of hydrogen to carbon in the synthesis gas produced after the treatment of raw material coke oven gas deviates far from the theoretical value (theoretical value of hydrogen to carbon ratio by volume ratio F=(H 2 -CO 2 ) / (CO+CO 2 )=2.0~2.05), resulting in that the hydrogen in the synthesis gas cannot be fully utilized, and is finally burned or released. Since the useful elements cannot be fully utilized, resources are wasted, and the eff...
