The Xuzhou Longxingtai project for producing 300,000 tons of methanol along with liquid ammonia utilizes coke oven gas as raw material, which is compressed, purified, converted, and then used to synthesize methanol. Synthetic ammonia is produced from methanol synthesis off-gases. The actual capacity is 346,000 tons per year of pure methanol, 2,500 tons per year of fusel oils, and 89,600 tons per year of synthetic ammonia. This project is currently the largest methanol and liquid ammonia production facility using coke oven gas in China. By utilizing the coke oven gas-to-methanol process technology and specialized catalysts and adsorbents owned as intellectual property by the Southwest Research Institute, the facility is designed to have an annual production capacity of 400,000 tons of pure methanol and 120,000 tons of liquid ammonia. The project is located in the Pizhou Economic Development Zone of Xuzhou City, and it represents the largest methanol production project using coke oven gas in China at present (the designed annual production capacity of the methanol plant is 400,000 tons). Project Overview: Xuzhou Longxingtai Energy Technology Co., Ltd. has integrated six enterprises, including Xuzhou Qiangsheng Urban Gas Co., Ltd., Xuzhou Tengda Coking Co., Ltd., Xuzhou Huayu Gas Co., Ltd., Xuzhou Zhongtai Energy Technology Co., Ltd., Xuzhou Dongxing Energy Co., Ltd., and Xuzhou Longshan Coking Co., Ltd., boasting a coking production capacity of 5.9026 million tons per year. Within the chemical industry cluster in Pizhou Economic Development Zone, to the north and west of Yizhou Technology Co., Ltd., the company is constructing a new coking facility with a capacity of 2.6 million tons – this is part of the “Xuzhou Longxingtai Energy Technology Co., Ltd. Project for Annual Production of 2.6 Million Tons of Coke, along with 300,000 Tons of Methanol and 100,000 Tons of Synthetic Ammonia (Yizhou Technology Phase III Project).” The total investment for this project is 4,933,529,600 yuan. Methanol production from 300,000 tons per year of coke oven gas: The coke oven gas is compressed, and an adsorption tower TSA is used to remove tar and naphthalene. Further desulfurization is carried out using a desulfurization tank and an iron-molybdenum converter. Through a preheater and a conversion reactor, the methane in the raw gas is converted into the gases CO and H2, which are necessary for methanol synthesis. Finally, methanol is synthesized and distilled to produce the final methanol product. The plant is designed with a capacity of 300,000 tons per year; the actual output is 346,000 tons per year of pure methanol, along with 2,500 tons per year of fusel oils. 100,000 tons per year of synthetic ammonia is produced using the off-gases from the methanol synthesis unit as raw material. The off-gas from the methanol synthesis alcohol washing tower is subjected to hydrogen extraction using PSA; the hydrogen and nitrogen are then mixed in a ratio of 3:1 and sent to the ammonia synthesis unit. The designed capacity of the ammonia synthesis plant is 100,000 tons per year, with an actual production volume of 89,600 tons per year.
