The Sai Ding low-temperature methanol washing system for the purification of coke oven gas in Shanxi Juyuan Coking Project, aimed at producing LNG/liquid ammonia/methanol – According to Sai Ding Company, on September 2, 2020, the company signed a general contract for the construction of such a low-temperature methanol washing facility for a coking project with an annual capacity of 3 million tons, with Shanxi Juyuan Coal Chemical Co., Ltd. This project is the world’s first installation to use low-temperature methanol washing technology as a replacement for the traditional wet desulfurization method in coking processes; it represents a significant technological innovation by Saiding Company in the field of coke oven gas purification for coking projects. This innovative technology utilizes low-temperature methanol washing to completely remove both organic and inorganic sulfur from coke oven gas, thereby solving the problem of the inability to effectively treat traditional coking desulfurization wastewater, and also providing a clean gas source for further processing of coke oven gas. This innovative technology holds broad prospects in the field of coke oven gas purification in coking engineering. Shanxi Juyuan Coal Chemical Co., Ltd. plans to utilize its existing production capacity of 1.92 million tons per year, along with an additional 1.17 million tons per year of capacity acquired through external purchases, to build a project for the upgrading and comprehensive utilization of coking operations at the former site of Jufeng Company, with a total capacity of 3.09 million tons per year. The total investment in the project is 6.2 billion yuan, covering an area of 988 mu. According to the Jinzhong Municipal Bureau of Industry and Information Technology, the project will be constructed in two phases. The first phase involves the construction of a coking plant with 2×60 chambers (6.55-meter JL6555D ramming coke ovens), capable of producing 1.5 million tons of coke per year, along with supporting facilities for coal preparation in coking, dry quenching of coke, recovery of by-products, as well as various auxiliary systems and environmental protection measures. The second phase involves the construction of a coking plant with 2×58 chambers (7.3-meter SWJ73-1 top-mounted coke ovens), having an annual capacity of 1.59 million tons; this plant will be accompanied by facilities for producing 210,000 tons per year of LNG, as well as 70,000 tons per year of liquid ammonia and 100,000 tons per year of methanol. According to Lingshi ** Network, in March 2020, the groundbreaking ceremony was held for the comprehensive upgrading and transformation project of Shanxi Juyuan Coal Chemical Co., Ltd., aimed at increasing its coal coking capacity to 3 million tons per year. On November 20, the construction kickoff ceremony for Furnace No. 1 was held for the 3 million tons per year coking upgrading and comprehensive utilization renovation project at Shanxi Juyuan Coal Chemical Co., Ltd.
