Progress on Chongqing Cabele Chemical’s 200,000-ton/year synthetic ammonia production project Author/Source: Gasification World Date: 2023-06-15 Clicks: 23 It has been learned recently that since the launch of the 100-day competition to accelerate project construction for Chongqing Cabele Chemical Co., Ltd.’s 200,000-ton/year synthetic ammonia production project on February 20, four general control milestones have been achieved, and three important control milestones have been completed on schedule; thus, the project completion rate stands at 77.8%. After three months of round-the-clock efforts, a key milestone was achieved: the installation of the main structure of the first-stage converter was completed. In the power distribution room, instrumentation and electrical engineering technicians worked hard to make the most of time, collaborating closely to carefully install and test the DCS, SIS, GDS, and UPS systems. They successfully completed the tasks of connecting the power distribution room to the power supply as well as powering on the DCS system, thus pushing the project construction to a new stage. Project Overview: The total investment in this project is approximately 650 million yuan. Once operational, it is expected to generate an annual profit and tax amount of over 100 million yuan. It will not only meet the substantial demand for liquid ammonia in the Changshou Economic Development Zone but also play a significant role in helping Chongqing Chemical & Pharmaceutical Holding (Group) Company achieve its goal of reaching a revenue of 100 billion yuan. Production is expected to begin next June, with qualified products being manufactured. Production is expected to begin next June after the chemical materials are fed into the process. It is reported that this project adopts the proprietary ammonia synthesis technology from the Swiss company Cassali, and through technical upgrades, further optimization of the production operation mode within the methanol plant is achieved. It can save 21,000 tons of standard coal per year, reduce CO2 emissions by about 60,000 tons per year, and cut hydrogen resource waste by around 88 million cubic meters per year. Through the use of off-gases and CO2 recovery, a circular economy system is established, enabling the formation of upstream and downstream industrial chains with enterprises in the Changshou Economic Development Zone. At the same time, the project reserved some production capacity and added 99.9% hydrogen products. 200,000 tons of synthetic ammonia are produced by using the off-gases from the Carbeler methanol plant, with some natural gas added as a supplement. The main processes include natural gas desulfurization (cobalt-molybdenum hydrogenation, ZnO desulfurization), first-stage steam reforming, high-temperature shift, membrane separation for hydrogen recovery, pressure swing adsorption (PSA) for carbon removal and hydrogen purification, and ammonia synthesis. Chongqing Cabele Chemical Co., Ltd. was established in 2008; it is a wholly-owned subsidiary of Chongqing Chempharm Holding (Group) Company, a key state-owned enterprise under the jurisdiction of Chongqing Municipality. The company operates a methanol production facility with an annual capacity of 850,000 tons, and its main products include methanol, syngas, and steam.
