The EPC project for the power station supporting Xinjiang Yihua’s melamine production facility commenced construction. Author/Source: Gasification World. Date: May 17, 2023. Clicks: 43. Recently, the inauguration ceremony for the EPC project of the power station intended to support Xinjiang Yihua Chemical Co., Ltd.’s (referred to as “Xinjiang Yihua”) annual melamine production capacity of 80,000 tons was held; this project is being carried out by the Northwest Branch of China National Chemical Engineering Group Corporation No. 16. The total investment for the EPC project of the power station is 770 million yuan, with a construction period of 550 calendar days; it is expected to be completed and put into operation by the end of December 2024. Once completed and put into operation, this project will enable the high-value sequestration and utilization of CO2, effectively solving the industry challenge related to the efficient and clean use of coal from the Junggar region in ammonia synthesis. By focusing on the recovery of CO2 for use as a gasification agent, it also **reduces carbon emissions**. This will make a greater contribution to the social and economic development of Xinjiang, enable the low-emission transformation of coal resources, uphold the concept of green and low-carbon development, and provide strong support for achieving the strategic goals of \"reaching carbon peak by 2030 and achieving carbon neutrality by 2060\".

(referred to as “Xinjiang Yihua”)’s project aimed at producing 80,000 tons of melamine per year. Xinjiang Yihua Company plans to invest in the construction of an 80,000-ton/year melamine production facility, while also upgrading the existing ammonia/sulfuric acid urea production plants as well as the steam supply systems within the plant. The elements included in this construction project are: (1) an 80,000-ton/year melamine production facility along with a waste gas recovery system ； (2) One 7000 m3/h standby gasification furnace ； (3) Simultaneously construct a 770t/h coal-fired boiler + 75MW back-pressure power generation unit. Melamine is produced using the latest high-pressure production technology from the Italian company Otech, making it the largest melamine manufacturing plant of its kind today. The melamine project uses molten urea from Yihua Company’s existing urea production facility as raw material; it does not increase the capacity for ammonia synthesis or urea production, nor does it raise the consumption of raw coal and fuel coal. Additionally, it does not alter the production process of the existing 600,000-ton per year alcohol-amine co-production plant. The melamine plant is equipped with an exhaust gas recovery system to treat the exhaust gases and ammonium-poor liquid generated by the plant, while producing urea as a by-product. All the urea produced as a by-product is used as raw material for the melamine production facility. The exhaust gas recovery system mainly includes an ammonia system, a high-pressure synthesis system, a low-pressure circulation system, an evaporation and condensation system, and a desorption and hydrolysis system. 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.
