The energy-saving technology upgrade project for coal gasification at Yichang Xingxing Lan Tian Technology Co., Ltd. is about to go into operation. Author/Source: Coal-based New Materials. Date: 2021-02-02. Clicks: 31. On January 25th, workers in the purification unit area of this upgrade project were conducting single-unit tests as preparation for full operation. This project is a representative example of industrial energy-saving upgrades in Yichang. It is located in the Xingfa Group’s Yidu Green Ecology Industrial Park, with a total investment of 2.386 billion yuan. Through upgrades and renovations, it has created a production line capable of producing 400,000 tons of synthetic ammonia per year, along with new facilities for gasification, purification, and related processes. At present, the main facilities and equipment for the entire project have been installed, and production is scheduled to begin in April. Once fully operational, it is expected to generate an annual output value of over 1 billion yuan. The gasification energy-saving technology upgrade project of Yichang Xingxing Lan Tian Technology Company is derived from the gasification energy-saving technology upgrade project of Hubei Chuxing Chemical Industry; it is a project that combines renovation work with new construction. The total investment for the project is 2,386,180,000 RMB. During the environmental impact assessment announcement in May 2016 for the original Hubei Chuxing Chemical Gasification Energy-Saving Technology Upgrade Project, the capacity was specified as 330,000 tons per year of synthetic ammonia. After the investor was changed to Yichang Xingxing Lan Tian Technology, the capacity for synthetic ammonia production increased to 400,000 tons per year; the location of construction remained unchanged, still within the site of the original Chuxing Chemicals upgrading project. The process route adopted for the energy-saving technology upgrade of Yichang Xingxing Lan Tian coal gasification is multi-nozzle opposed water-coal slurry gasification (1 in operation and 1 as standby, with a gasifier inner diameter of 3400 mm and a design pressure of 6.5 MPa), supplemented by controlled heat transfer shift reaction, low-temperature methanol washing, liquid nitrogen washing for purification, and the Cassali ammonia synthesis technology.
