Recently, the low-carbon integrated project for the clean utilization of resources through photoelectrochemical hydrogen production, undertaken by the Third Construction and Engineering Company of China National Chemical Engineering Corporation, was officially launched at Xinjiang Haoyuan Chemical Co., Ltd. The project is located in the BeisanTai Circular Economy Industrial Park in Jimsar County. With a total investment of 7,066,005.1 million yuan, it takes advantage of the coal and solar energy resources available in Jimsar County and its surrounding areas to carry out on-site conversion processes for clean and low-carbon utilization, thereby producing products such as green hydrogen, methanol, ethanol, synthetic ammonia, and high-nitrogen water-soluble compound fertilizers. The project uses coal as raw material to produce crude gas through a gasification unit, and the crude gas is then processed in a purification unit to yield refined gas ； Refined gas, together with syngas composed of green hydrogen and nitrogen, is used as raw materials in ammonia synthesis plants to produce liquid ammonia ； Liquid ammonia and carbon dioxide produced by the purification device are used to produce urine ； Urine is further used to produce high-nitrogen water-soluble compound fertilizers, diesel engine exhaust cleaners, and melamine ； Green hydrogen and carbon dioxide produced by purification devices are used to produce green methanol. Upon completion of the project, the main products will be high-nitrogen water-soluble compound fertilizers, diesel engine exhaust cleaners, melamine, liquid ammonia, food-grade CO2, sulfuric acid, ammonium sulfate, and methanol. The project will be constructed in three phases. Phase 1 will involve the construction of facilities for producing 400,000 tons per year of synthetic ammonia, 500,000 tons per year of high-nitrogen water-soluble compound fertilizers, and 20,000 tons per year of hydrogen via electrolysis of water; completion is expected by November 2026. The components of the first phase of construction include a gasification unit, a gas purification unit, a synthetic ammonia production plant with an annual capacity of 400,000 tons, a plant for producing urine (an intermediate product) at an annual capacity of 500,000 tons, a plant for producing high-nitrogen water-soluble compound fertilizers at an annual capacity of 500,000 tons, a plant for producing diesel engine exhaust cleaners at an annual capacity of 200,000 tons, a melamine production plant with an annual capacity of 120,000 tons, a plant for producing food-grade CO2 at an annual capacity of 100,000 tons, and a plant for producing hydrogen through water electrolysis at an annual capacity of 20,000 tons. Sinochem Third Construction’s Third Construction Engineering Company was responsible for the civil engineering work of the project’s gasification unit. The gasification unit presents high technical and construction challenges, and is one of the most critical units in the entire project.
