The melamine production facility at Guangxi Chuanhua Tianhe Potash Fertilizer Company has resumed operations. According to a report from the company in April 2026, it recently held a mobilization meeting for the restart of the melamine production facility, outlining plans for its inspection, maintenance, and resumption of operations. Affected by domestic and international market conditions, the prices of melamine products have been rising steadily, and export orders continue to increase. Melamine products are currently in a favorable market situation, which led to the decision to restart the melamine production facilities. Since 2022, facing a challenging market environment, Sichuan Huahua Tianhe Potash Fertilizer Company has carried out various improvements, such as ammonia-carbon separation to increase the added value of its products, reducing natural gas consumption, and recovering low-grade heat energy, all in order to enhance the market competitiveness of its products. The Guangxi Chuanhua Tianhe potassium fertilizer project uses potassium chloride and sulfuric acid as raw materials to produce potassium sulfate via the Mannheim process, with hydrochloric acid (31% concentration) as a by-product. Melamine is produced using urea as a raw material through a gas-phase quenching process, and 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. The composition of the first-phase production capacity is 240,000 tons per year of potassium sulfate, 50,000 tons per year of powdered water-soluble fertilizer, 50,000 tons per year of liquid water-soluble fertilizer, 50,000 tons per year of melamine, and 151,200 tons per year of ammonium chloride. In May 2021, the melamine/ammonium chloride plant was put into operation.
