It has been reported recently that the civil engineering work for Henan Jindadi Chemical Co., Ltd.’s project aimed at energy-saving upgrades and the development of low-carbon salt-nitrogen-fertilizer products in Wuyang County, Luohe City, has been fully completed, with trial production set to begin in August. It is reported that the Jindadi United Alkali Green Transformation Industrial Park project, with a total investment of 12 billion yuan, is the largest single-investment project in Luohe City in recent years. In the industrial park project, the caustic soda production unit utilizes the domestically leading soda-making and crystallization systems developed by Jinshan Group, while the ammonia synthesis process makes use of the world’s most advanced technologies, such as the Casari synthesis system from Switzerland and Siemens circulation compressors from Germany. Multiple sub-projects employ advanced core technologies both internationally and domestically, resulting in process equipment and energy efficiency levels that are among the best in the world. The Henan Jindadi United Alkali Green Transformation Industrial Park project uses a water-cooled wall directly-connected waste boiler gasifier (Jinhua Furnace 3.0) manufactured by Shanxi Yangmei Chemical Machinery (Group) Co., Ltd.; the gasification unit operates in a two-in-use-one-backup configuration, with a gasification pressure of 6.5 MPaG. After transformation and heat recovery, low-temperature methanol washing, and liquid nitrogen washing for purification, ammonia synthesis is carried out. All the liquid ammonia is sent to the ammonia absorption section of the caustic soda plant, where soda ash and baking soda are produced, with ammonium chloride being generated as a by-product. The production capacity is 600,000 tons per year of synthetic ammonia, 700,000 tons of soda ash, 1.6 million tons of baking soda, 1.8 million tons of ammonium chloride and compound fertilizers, as well as 3 million tons of salt produced by vacuum method. The 450,000 tons per year synthetic ammonia plant in Phase 3 of Henan Jindadi was put into operation in February 2019. Full capacity operation was achieved in May of the same year. The fourth phase of the 600,000 tons per year soda ash and associated ammonia synthesis project came online in December 2021. The Phase 4 project of Henan Jindadi, with a production capacity of 600,000 tons per year of sodium bicarbonate, is accompanied by a synthetic ammonia plant with an output of 600,000 tons per year. Two Jinhua furnaces were added in phase four. The newly added Jinhua furnaces are connected to the main pipelines of the three Jinhua furnaces in the original Phase III 450,000 tons/year ammonia synthesis project, serving as backups for one another, thus forming a gasification island with four units in operation and one as backup. Project Overview: Henan Jindadi Chemical Co., Ltd. has acquired 1,100 mu of new land in the industrial cluster area of Wuyang County to build the Jindadi Green Transformation Industrial Park for salt chemicals. This project aims to create the largest innovative salt chemicals manufacturing base in the country. The Henan Jindadi United Alkali Green Transformation (Phase V) project is an expansion project; the 700,000 tons per year of soda ash produced as part of this project consists of the relocation of existing facilities – specifically, the 400,000 tons per year soda ash production facility owned by Henan Jintian Chemical, which is also part of the Henan Jinshan Chemical Group and located in Huojia, Xinxiang, as well as the 300,000 tons per year soda ash production facility owned by Henan Jinshan Chemical and located in Mengzhou, Jiaozuo. In other words, it is a project that involves closing two facilities and establishing one new one in their place. The main components of the project include the construction of one new 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 ammonia synthesis facility (600,000 tons per year). The project uses coal as raw material and employs the water-coal slurry gasification process (3 new Jinhua furnaces, 2 in operation and 1 as backup) to produce liquid ammonia, which is entirely used in the subsequent production of caustic soda. In July 2022, the Henan Department of Ecology and Environment suspended the approval process for the \"Henan Jindadi Chemical Co., Ltd. Green Transformation Industrial Park Project Environmental Impact Report\", returning the report due to shortcomings in the engineering analysis and the assessment of pollution prevention measures. 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 under pressure to the ammonia absorption section of the caustic soda production plant using liquid ammonia, where soda ash and baking soda are produced, with ammonium chloride as a by-product. The production capacity is 600,000 tons per year of synthetic ammonia, 700,000 tons of soda ash, 1.6 million tons of baking soda, 1.8 million tons of ammonium chloride and compound fertilizers, as well as 3 million tons of salt produced by vacuum distillation. Upon completion, the project is expected to 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. On December 12, 2021, the 600,000 tons per year soda ash production project at Henan Jindadi Chemical Co., Ltd. completed all its processes, and synthetic ammonia was produced successfully with a single batch of raw materials. The 450,000 tons per year synthetic ammonia plant in Phase 3 of Henan Jindadi was put into operation in February 2019. Full capacity operation was achieved in May of the same year. The fourth phase of the 600,000 tons per year soda ash and associated ammonia synthesis project came online in December 2021. The Phase 4 project of Henan Jindadi, with a production capacity of 600,000 tons per year of sodium bicarbonate, is accompanied by a synthetic ammonia plant with an output of 600,000 tons per year. Two Jinhua furnaces were added in phase four. The newly added Jinhua furnaces are connected to the main pipelines of the three Jinhua furnaces in the original Phase III 450,000 tons/year ammonia synthesis project, serving as backups for one another, thus forming a gasification island with four units in operation and one as backup.
