What is the process used in Tianqing Company’s ammonia synthesis plant, and what is its production capacity? ?

Introduction to Tianqing: Tianqing Company was established in 2010 and is located in the Qinbei Park of the Industrial Agglomeration Zone in Qinyang City, Henan Province. Its registered capital is 1.16 billion yuan, and it has more than 800 employees. The company is mainly engaged in the production and sales of coal-based gas, synthetic ammonia, urea, and other fertilizer and chemical products. The company plans to cover an area of 3,500 mu and invest in the construction of a new modern coal chemical project. The total investment for the first phase is 3.86 billion yuan; it covers an area of 1,000 mu, and its designed production capacity is 570,000 tons of total ammonia per year. The facility includes specialized railway lines, gas pipelines, back-pressure power generation systems, as well as residential areas for employees. The entire production process is controlled by DCS computers, offering advantages such as low raw material costs, advanced manufacturing technology, and strong product competitiveness. It is capable of generating annual sales revenue of 2 billion yuan and a total profit of 300 million yuan. Basic information on the natural gas project: Building on the foundation and advantages of the company’s first-phase project, an additional investment of 440 million yuan has been made to construct a natural gas production facility. The main construction components include methanation, LNG liquefaction, and storage and transportation facilities. This project uses the abundant 15# coal supplied by Jinmei Group as raw material, and employs advanced domestic and international coal gasification technologies under high temperature and pressure to react the coal with gasifying agents, thereby producing crude gas. This gas is then subjected to purification processes such as shift reaction, desulfurization, decarburization, and dehydration, and through five stages of methanation reaction, it is converted into methane. The resulting methane is sent to a cryogenic tank where it is finally cooled to a depth sufficient for liquefaction, thus producing LNG. This project utilizes patented technologies from the British company David and well-known domestic listed companies. 1 million cubic meters of natural gas can be liquefied per day, producing 700 tons of LNG. The project has completed its investment and construction phases; low-temperature cryogenic LNG was produced in July, while product CNG was produced on July 25.
