The melamine production facility part of the Guangxi Chuanhua Potash Fertilizer project is set to go into operation in February next year. Yangtze River Nitrogen Fertilizers and Methanol, 2020-11-19. According to a report in the Beihai Daily dated November 17, 2020, the civil construction and decoration work for the potassium sulfate production plant in the Guangxi Chuanhua Tianhe Potash Fertilizer project is nearing completion, while equipment installation is underway in the ammonium chloride and melamine production plants； The renovation of the duty building and cafeteria, as well as the installation of water and electricity systems, are nearing completion; the office building is currently under renovation ； The equipment in the substation is currently being commissioned... On the morning of November 2, at the Tieshan Port (Linhai) Industrial Zone, construction was in full swing at the Chuanhua project, which has a total investment of 1.3 billion yuan and is designed to produce 480,000 tons of high-quality potassium sulfate per year. According to the deputy general manager of Guangxi Chuanhua Tianhe Potash Fertilizer Co., Ltd., the potassium sulfate production facility will be fully mechanically completed by the end of this month. Later this month, some units will be put into operation. The melamine plant and the ammonium chloride plant are expected to be completed by the end of December, with operations starting in February next year. The production of potassium sulfate at Guangxi Chuanhua Tianhe Potash Fertilizer Company is carried out using potassium chloride and sulfuric acid as raw materials, via the Mannheim process, with hydrochloric acid (31% concentration) as a by-product. Melamine production uses urea as a raw material and employs a gas-phase quenching process; the exhaust gas containing ammonia needs to be treated. Hydrochloric acid produced as a by-product of potassium sulfate is used, along with triamine off-gases, to produce ammonium chloride.
