Voluntary Information Disclosure Announcement regarding the commissioning of the project undertaken by our subsidiary, Xinjiang Yihua Chemical Co., Ltd., which involves an annual production capacity of 400,000 tons of synthetic ammonia and 600,000 tons of urea. The Board of Directors of the Company guarantees that the information disclosed herein is true, accurate, and complete, with no false records, misleading statements, or any omissions. The project undertaken by the Company’s subsidiary, Xinjiang Yihua Chemical Co., Ltd., to produce 400,000 tons of synthetic ammonia and 600,000 tons of urea per year—which was approved at the fifth meeting of the sixth session of the Board of Directors in 2010 and at the second extraordinary general meeting of shareholders in 2010—has recently been put into operation, with qualified products now being produced. Hereby announced. Board of Directors of Hubei Yihua Chemical Industry Co., Ltd. December 30, 2011. It is understood that the project utilizes a clean production process. The technological process is as follows: Of the total output, 200,000 tons of synthetic ammonia are produced using waste gas from semi-coke as raw material; after thorough purification, this gas is mixed with semi-water gas generated during gas production ； The process involves gas production using Lurgi furnaces, low-temperature shift conversion, pressure swing adsorption for decarburization, and purification of syngas via alcohol-hydrocarbon synthesis; urea is produced using a modified total-recycle aqueous solution process. Hubei Yihua announced that on December 30, 2011, its subsidiary Xinjiang Yihua Chemical Co., Ltd. put into operation a project with an annual production capacity of 400,000 tons of ammonia and 600,000 tons of urea.
Is it operating at full load? Xinjiang suffers from water shortages; how effective is deep hydrolysis?
The urea process is a bit outdated; I wonder how effective any improvements would be? We have a new energy-saving process for increasing urea production in a high-pressure loop, which involves a steam consumption rate of 0.9–1.0 tons of steam per ton of urea. This process features stable operation under both high and medium pressures; under the same production load conditions, it can increase output by 30–50%.
