[Jinhua Furnace] Successful feeding of the 600,000-ton synthetic ammonia project in Phase 5 of Henan Jindadi On November 18, 2023, at 07:40, the first feeding phase of Henan Jindadi Chemical Co., Ltd.’s project for energy-saving upgrades to alkali production processes and the development of low-carbon salt and nitrogen fertilizer products (referred to as “Phase 5 of Jindadi project”) was completed successfully. At present, all technical parameters are within normal ranges following this feeding process, and the project has entered the trial production stage. On November 18, 2023, the project commissioned its second gasifier, marking the official entry into full-scale operation of the ammonia synthesis unit in Phase 5 of Jindadi. The Phase 5 project of Jindadi utilizes the water-cooled wall directly connected to a waste boiler gasifier (Jinhua Furnace 3.0) technology. There are three Jinhua Furnaces 3.0 units, with two in operation and one as a backup; the gasification pressure is 6.5 MPaG, and the total gas output is 157,000 Nm3/h (CO + H2). The waste boilers of the two Jinhua Furnace 3.0 units produce 101 t/h of high-pressure steam at 7.0 MPa. Designed by China Tianchen Engineering Co., Ltd., the two Jinhua furnaces 3.0 were successfully lifted on February 18, 2023, and the gasification furnace was successfully ignited in October 2023. The Phase 5 project of Henan Jindadi, with an annual capacity of 600,000 tons of synthetic ammonia, includes the construction of one soda ash production facility (700,000 tons per year of soda ash, 1.6 million tons per year of baking soda, and 1.8 million tons per year of ammonium chloride), one compound fertilizer production facility (800,000 tons per year), one vacuum salt production facility (3 million tons per year), and one synthetic ammonia production facility (600,000 tons per year). The project uses coal as raw material and employs the water-coal slurry gasification process to produce liquid ammonia, which is entirely used in the subsequent production of caustic soda. Upon completion, the project will become the largest food-grade baking soda production base in China, as well as the world’s largest production base for caustic soda and ammonium chloride. The 450,000 tons/year synthetic ammonia relocation and renovation project of Henan Jindadi Chemical Co., Ltd. (hereinafter referred to as the Jindadi Phase III project) adopts the water-cooled wall directly connected to the waste boiler gasifier (Jinhua Furnace 3.0) technology. Three Jinhua Furnace 3.0 units are used, with two in operation and one as a backup; the gasification pressure is 6.5 MPaG, and the total gas volume is 156,000 Nm3/h (CO + H2). The waste boilers of the two Jinhua Furnace 3.0 units produce 101 t/h of high-pressure steam at 7.0 MPa. Designed by China Tianchen Engineering Co., Ltd., the project achieved successful commissioning on February 2, 2019, and reached full capacity on May 8, 2019. The 600,000 tons/year soda ash project of Henan Jindadi Chemical Co., Ltd. (hereinafter referred to as the Jindadi Phase IV project) utilizes the water-cooled wall directly connected to the waste boiler gasifier (Jinhua Furnace 3.0) technology. Two Jinhua Furnace 3.0 units are installed (with one as a backup), the gasification pressure is 6.5 MPaG, and the total gas volume is 156,000 Nm3/h (CO + H2). The waste boilers of these two Jinhua Furnace 3.0 units produce 101 t/h of high-pressure steam at 7.0 MPa. Designed by China Wuhuan Engineering Co., Ltd., this project achieved successful commissioning in December 2021 on the first attempt. The Phase 4 project of Jindadi has added two more Jinhua Furnace 3.0 units; once they are put into operation, together with the three Jinhua Furnace 3.0 units already in use at the Phase 3 plant of Jindadi, this will result in a gasification complex with four units in operation and one as backup. The Henan Jindadi United Alkali Green Transformation Industrial Park project has a total investment of 12 billion yuan, covers an area of 1,200 mu, with an investment intensity of 10 million yuan per mu. The project mainly includes facilities for producing 600,000 tons of synthetic ammonia, as well as 700,000 tons of soda ash per year, 1.6 million tons of baking soda, 1.8 million tons of ammonium chloride and compound fertilizers, and 3 million tons of salt produced via vacuum distillation. The project uses Shenmu coal as raw material, and crude gas is produced through reaction in a water-coal slurry gasifier ； The raw gas is purified into clean gas after passing through the shift and heat recovery units, as well as the low-temperature methanol washing unit. The purified gas, after being refined through liquid nitrogen washing and compressed, is sent to the alkali raw material synthesis unit. The acidic gas generated by the purification unit is sent to the sulfur recovery unit to produce sulfur products. All products are sent to the ammonia absorption section of the liquid ammonia pressurization caustic soda production plant, where they are used to produce soda ash and baking soda, with ammonium chloride being produced as a by-product.
