The gasifier in Hubei Yunhua’an’s 300,000-ton synthetic ammonia project was successfully ignited. Author/Source: Gasification World. Date: July 7, 2021. Clicks: 7. On July 1, the gasifier of the synthetic ammonia upgrading project at Hubei Yunhua’an, constructed by the Second Branch of Thirteenth Chemical Construction Company, was successfully ignited and preheated on the first attempt. The successful heating and ignition of the gasifier mark that the project will now officially enter the final stages of completion. On July 1, during the heating-up process of the gasifier, the project team carried out proper safety and technical briefings and actively cooperated with the workshop. By feeding preheated water into the cooling water loop of the gasifier, introducing steam to drive the start-up extractor and create a negative pressure inside the gasifier’s furnace, as well as introducing natural gas, the permanent flame in the preheating burner was successfully ignited. The flame inside the furnace burned normally, and the gasifier began its official heating-up process. Project Overview: The Hubei Yunhua An synthetic ammonia project has a total investment of 3.5 billion yuan. It is located in the Tianzhen Industrial Park in Wuxue City, Hubei Province, and produces synthetic ammonia using coal as raw material. It includes major facilities such as air separation, coal gasification, synthetic ammonia production, and sulfur recovery, along with supporting utility systems. The construction is carried out by Thirteen Chemical Construction Company, and the work includes the construction of coal slurry preparation systems, coal slurry feeding systems, gasification units, flash vaporization frameworks, vacuum filtration frameworks, internal utility tunnels, storage and transformation substations, as well as facilities for the storage and transportation of raw materials and coal. Xiangyun Co., Ltd.’s project to produce 300,000 tons of synthetic ammonia per year is a key initiative under the company’s 13th Five-Year Strategic Development Plan. This project utilizes a new type of multi-nozzle water-coal slurry high-pressure gasification technology, achieving a carbon conversion rate of 99% ； By adopting internationally advanced coal purification and utilization technologies, the dry basis content of the effective gas exported reaches 89%, **reducing energy consumption in subsequent processing stages. Gas purification employs low-temperature methanol washing and liquid nitrogen washing technologies, which are energy-efficient and environmentally friendly. The project is located in WuXue City, Hubei Province, with a total investment of 3.5 billion yuan. It uses coal as raw material to produce synthetic ammonia, and includes major units such as air separation, coal gasification, synthetic ammonia production, and sulfur recovery, along with the associated utility systems. Once completed, the project will produce 1,200 tons of synthetic ammonia per day, sufficient to meet the demand for ammonia as a raw material in phosphate fertilizer production lines. It will help to avoid safety risks associated with the transportation of liquid ammonia, as well as a range of issues related to existing synthetic ammonia plants, such as low production capacity, high energy consumption, and significant pollution.
