Description
Technical Field
[0001] The utility model belongs to the technical field related to chemical production, and particularly relates to a desulfurization and purification device for methanol synthesis gas produced by alcohol and ammonia co-production. Background Art
[0002] Alcohol-ammonia co-production of methanol is a chemical production process that combines the production processes of synthetic methanol and synthetic ammonia to achieve efficient utilization of raw materials and energy. This co-production process can reduce production costs, reduce energy consumption, and reduce environmental pollution. In the field of coal chemical industry, alcohol-ammonia co-production technology has become an important technical component in the production of synthetic ammonia, which helps to increase the production capacity of methanol and synthetic ammonia and reduce carbon dioxide emissions. During operation, a small amount of hydrogen sulfide impurities will remain in the carbon dioxide produced, which will affect the production of methanol in the subsequent production process. Therefore, it is necessary to remove hydrogen sulfide through copper sulfate solution, but it still has the following disadvantages in actual use:
[0003] During the desulfurization and purification process of methanol synthesis gas produced by the co-production of alcohol and ammonia, the hydrogen sulfide impurities in carbon dioxide react with copper sulfate to produce copper sulfide precipitation. After the copper sulfide precipitation is produced, it needs to be manually scraped and collected, which is not convenient to operate;
[0004] During the desulfurization and purification process of methanol synthesis gas produced by the co-production of alcohol and ammonia, hydrogen sulfide gas is directly removed through copper sulfate solution. During the operation, the copper ions in the solution will continuously react and be removed, causing the copper ion content to decrease. The reactor needs to be opened for replenishment or replacement, which is not convenient to operate. Utility Model Content
