Hubei Xinyi Chemical Clean Coal Pressurized Gasification Polygeneration Technical Relocation and Upgrading Project (referred to as the Amino Alcohol Project) successfully hoisted the ammonia synthesis tower author/source: gasification world date: 2023-03-03 Click rate: 9 On February 28, 2023, the ammonia synthesis tower of Hubei Xinyi Chemical Co., Ltd.’s clean coal pressurized gasification polygeneration technical transformation, relocation and upgrade project (referred to as the ammonia alcohol project) was successfully hoisted. Complete key node tasks in the project construction phase. The ammonia synthesis tower is the core equipment of the ammonia synthesis unit and the heaviest piece of equipment in this project. Ammonia synthesis adopts Casale low-pressure synthesis technology, with a synthesis pressure of 140 kg and a daily production of 2,000 tons of ammonia. Structurally, it adopts a direct connection design with downstream equipment to maximize heat recovery and ensure the intrinsic safety of the device. The Xinyi ammonia synthesis project adopts multi-nozzle opposed coal-water slurry gasification, controllable heat transfer, low-temperature methanol washing, liquid nitrogen washing and other gas purifications, Casale low-pressure ammonia synthesis, Linda methanol synthesis, etc. The product scale is an annual output of 460,000 tons of synthetic ammonia and 90,000 tons of methanol, with a total ammonia alcohol capacity of 550,000 tons. On December 28, 2022, Hubei Xinyi Chemical Co., Ltd.’s clean coal pressurized gasification polygeneration technical transformation, relocation and upgrade project (referred to as the ammonia alcohol project) successfully hoisted the gasifier in one go. Project overview It is reported that Hubei Xinyi Chemical Co., Ltd.’s clean coal pressurized gasification polygeneration technical transformation The relocation and upgrade project (referred to as the ammonia alcohol project) is the leading project for the overall relocation of Yihua Group's Yiting Park to the Tianjiahe area of Yaojiagang Chemical Park. The total investment is 2.9 billion yuan. The product scale is an annual output of 460,000 tons of synthetic ammonia and 90,000 tons of methanol, with a total ammonia alcohol capacity of 550,000 tons. It mainly provides liquid ammonia and methanol raw materials for downstream phosphorus compound fertilizer units and polyol units. The project adopts the world's leading multi-nozzle opposed coal-water slurry pressurized gasification technology, isothermal transformation technology, low-temperature methanol washing, desulfurization and decarbonization integration technology, Swiss Casali low-pressure synthesis technology, and the core unit adopts imported equipment. Hubei Yihua Chemical Co., Ltd. was established in 1977. It is a state-controlled listed company and the core subsidiary of Hubei Yihua Group, one of the top ten representative enterprises in China's petrochemical industry. The company is mainly engaged in the production and sales of chemical fertilizers and chemical products. The company is an important chemical fertilizer manufacturer in the country and the third large-granule urea manufacturer in the country. The company has a 100,000 tons/year insurance powder production device ； Three sets of synthetic ammonia production units ； Three sets of urea production units with a total designed production capacity of 600,000 tons/year ； Two sets of ion membrane caustic soda production equipment with a total designed production capacity of 100,000 tons/year. In 2019, Hubei Xinyi Chemical Co., Ltd., a subsidiary of Yihua Group, undertook the construction of the upgrade and reconstruction project of the traditional process ammonia synthesis unit.
