http://www.anchunjishu.com/index.asp At 02:08 on August 30, 2016, the first ignition of Unit B of the space gasification plant for the Lutianhua project, undertaken by Changzheng Chemical Engineering Co., Ltd., was successful. This successful ignition marks the completion of an important milestone in the project’s testing phase, creating key conditions for the smooth feeding of material into the gasifier going forward. The facility is located in Bingling Village, Xinele Town, Naxi District, Luzhou City, on industrial land within the Luzhou Chemical Industry Park. Using coal from the ancient Xuyi mining area in Sichuan as raw material, this project involves the construction of 4 space gasification furnaces with a diameter of 3.2 meters. The scale of coal-to-gas production is designed to match the raw gas requirements of Lutianhua’s existing plant, which has a methanol production capacity of 440,000 tons per year and a synthetic ammonia production capacity of 600,000 tons per year. Meanwhile, sulfur, sulfuric acid, and argon are produced as by-products. The power generation capacity of the associated coal-fired unit is 14,782 kW·h/h. The main components of this project include coal preparation systems such as coal sorting and coal grinding, gasification and gas purification systems (including gasification, shift reaction, desulfurization and decarbonization, and liquid nitrogen washing), as well as a sulfur recovery system ； Auxiliary facilities include air separation plants, coal-fired boiler rooms, circulating water stations, water treatment plants, wastewater treatment plants, treated effluent water treatment plants, refrigeration plants, carbon dioxide compression plants, flares, fire protection systems, and accident water tanks ； Storage and transportation facilities include coal unloading equipment, belts, silos, slag storage tanks, boiler ash storage areas, boiler slag storage areas, methanol storage tanks for low-temperature methanol washing, liquid oxygen (nitrogen, argon) storage tanks, ammonia tanks in the refrigeration plant, methanol maintenance tanks, as well as warehouses for raw materials, auxiliary materials, and by-products. However, for the synthetic ammonia feed gas and methanol feed gas produced by this project, no gas tanks are installed; instead, they are transported directly via pipelines to Lutianhua for use.
