Recently, the largest scale production of synthetic ammonia and urea from coke oven gas as raw materials was completed by the Shanxi Provincial Chemical Design Institute. At present, the production scale is 180,000 tons/year, and the 300,000 tons/year urea project has been invested and built by Fengxi Huarui Company in the Xinyi County Coal Chemical Industry Park in Shanxi Province. The project is expected to be put into operation in February 2007. .
Taking coke oven gas as raw material for large-scale production of synthetic ammonia and processing urea, the difficulty of the process is as follows: raw gas purification is difficult; the feed gas conversion device is huge; the total carbon content in the gas is not in proportion to the ammonia it obtains, and carbon is needed; In the carbon process, the CO2 content in the shift gas is low; the operating pressure of the system is not high. Shanxi Provincial Chemical Design Institute mobilized the expertise of the hospital for these process difficulties, and absorbed and applied the research results of the relevant research collaboration units, optimized the design process and design scheme, and successfully completed the design task of the project.
After the project is put into production, it can use about 2.88×108Nm3 of coke oven gas per year, and the cost per ton of ammonia can be reduced by about 40% compared with coal as raw material, which can achieve a win-win situation for coke production enterprises and chemical fertilizer production enterprises in the park.
Shanxi Province is the main producer of coke in China, and a large amount of coke oven gas produced during the coking process has not been rationally utilized. On the one hand, it has caused great waste of resources. On the other hand, it has also increased environmental pollution and governance costs. Combining traditional coking industry and chemical fertilizer industry organically, coke oven gas is used as raw material to produce synthetic ammonia and processed urea, which realizes the conversion of coke oven gas to waste and reduces the production cost of synthetic ammonia and urea.
