Progress in the construction of Baotou Steel Qinghua ammonia synthesis project. Author/Source: SEDIN Engineering Co., Ltd. Date: November 23, 2021. Page views: 24. On November 20, the commissioning of the substation for the ammonia synthesis project undertaken by SEDIN as the EPC contractor was successfully completed. The substation is now ready to receive high-voltage power supply, marking the beginning of the trial operation phase for the entire plant. Inner Mongolia Baogang Qinghua Coal Chemical Co., Ltd. is located within the industrial park in Wulat Qianqi County, Bayannur City, Inner Mongolia. The site is situated 142 km west of Linnhe District, where Bayannur City is located. The company currently operates 4 TJL5550D-type coke ovens with 55 chambers each, producing 2.1 million tons of coke, 200,000 tons of methanol, and 90,000 tons of coal tar per year. The methanol synthesis off-gases generated during the methanol production process are sent to the fuel gas network for use as fuel, which represents a waste of this hydrogen-rich, clean gas. In light of this, the company has submitted an application to the Ulaat Qianqi Bureau of Industry and Information Technology to build a new facility capable of producing 70,000 tons of ammonia per year through methanol production. The project code is 2020-150823-25-03-005708. This construction project will utilize PSA technology to extract hydrogen from the existing methanol off-gases, and through processes such as methanation, syngas compression, and ammonia synthesis, it will achieve an annual ammonia production capacity of 70,000 tons.
