Xinjiang Yihua Company plans to invest in the construction of an 80,000-ton/year melamine production facility along with associated infrastructure. It also intends to upgrade the existing ammonia/sulfuric acid production units and the steam supply systems within the plant. The elements included in this planned construction are: (1) an 80,000-ton/year melamine production facility along with exhaust gas recovery systems； (2) A backup gasification furnace with a capacity of 6,000 m3/h; this furnace is part of the ammonia/urea gasification unit and serves as a backup device ； The newly built backup gasifier utilizes the fluidized bed technology developed by Zhongke Hefei Gasification Technology Co., Ltd., and is consistent with the process and equipment selection of the existing gasifiers. (3) Simultaneously construct a 770t/h coal-fired boiler + 75MW back-pressure generator set. Simultaneously, a desalination plant with a capacity of 300 m3/h, a reclaimed water reuse plant with a capacity of 150 m3/h, a circulating cooling water plant with a capacity of 120,000 m3/h, an air compression station, and an office building will be constructed; other facilities such as water supply, power supply, and wastewater treatment will make use of the existing infrastructure in the factory area. The main production unit to be constructed in this phase, the melamine plant, will be built on the vacant land to the east of the existing melamine plant within the factory complex. The infrastructure and supporting facilities already in place at the factory can supply water and electricity to this project, while Yihua Company can provide materials such as molten urea, liquid ammonia, and fuel gas through its internal supply systems, thus creating favorable conditions for the construction and operation of this project. The total investment for this project is 2,691.38 million yuan, of which 70.95 million yuan is allocated to environmental protection. Thus, environmental protection investments account for 2.64% of the total investment. The newly built backup gasifier utilizes the fluidized bed technology developed by Zhongke Hefei Gasification Technology Co., Ltd., and is consistent with the process and equipment selection of the existing gasifiers. This facility is a backup unit; it does not increase the raw material consumption of Yihua Company’s existing ammonia/sulfuric acid urea production plants, nor does it result in any additional pollutant emissions.
