The coal slurry preparation and slag treatment units for the Cangzhou Xuyang caprolactam expansion project were successfully handed over. Author/Source: Thirteenth Chemical Construction Company. Date: 2022-07-05. Clicks: 12. On June 29, the coal slurry preparation and slag treatment units as part of the Cangzhou Xuyang caprolactam expansion project were successfully delivered, and the project owner issued a handover certificate to the project team. Project Overview: The caprolactam expansion project of Cangzhou Xuyang Chemical Co., Ltd. requires a total investment of 4.5 billion yuan. It involves the construction of a 300,000-ton/year caprolactam plant, a 270,000-ton/year ** plant, a 343,000-ton (35%)/year hydrogen peroxide plant, a 450,000-ton/year sulfuric acid plant, a coal-based hydrogen production facility, a 300,000-ton/year ammonia synthesis plant, as well as supporting raw material facilities and utility systems. Upon completion, the project is expected to enable the company to achieve annual sales revenue of 10 billion yuan and total profits and taxes of 2 billion yuan, while creating 1,000 jobs. Cangzhou Xuyang Chemical Co., Ltd.’s caprolactam expansion project is a large-scale modern chemical facility that produces liquid caprolactam using raw materials such as lignite coke, benzene, fuming sulfuric acid, and alkali solutions. The project is located within the Cangzhou Xuyang Chemical Industrial Park. The construction includes a caprolactam plant with an annual capacity of 300,000 tons, an ammonium sulfate plant with an annual capacity of 450,000 tons, a ** plant with an annual capacity of 270,000 tons, a synthetic ammonia plant with an annual capacity of 300,000 tons, a hydrogen production plant using lignite with a capacity of 80,000 Nm3/h, and a hydrogen peroxide plant with an annual capacity of 120,000 tons (equivalent to 100% by weight). The Cangzhou Xuyang caprolactam expansion project uses 3 Jinhua furnaces model 3.0. Two in operation and one as backup, vaporization pressure of 6.7 MPa, gas flow rate per furnace of 65,000 m3/h (CO+H2). The raw material for the PSA hydrogen production unit in Cangzhou Xuyang Chemical Co., Ltd.’s caprolactam expansion project is hydrogen produced from lignite; the operating pressure of this unit can reach 5.9 MPa, making it the pressure-rated pressure swing adsorption unit with the highest pressure currently in use at Southwest Chemical. The volume of hydrogen gas produced is 55,000 Nm3/h. This project utilizes some of the world’s most advanced manufacturing technologies, offering high production capacity per production line and low investment costs. It features significant improvements in terms of operation control and energy utilization, with low consumption of raw materials and utility resources. It requires less benzene per ton of caprolactam produced, generates less sulfuric acid as a by-product, and ensures high-quality products whose various specifications far exceed the established standards. It can be applied to the production of finely woven or high-speed spun textiles as well as special engineering products to meet various needs, thus laying a solid foundation for the development of a new polyamide materials industry in the Bohai New Area. Cangzhou Xuyang Chemical Co., Ltd. is a subsidiary of the Xuyang Group; it was established in 2011 and is a chemical enterprise focused on the production of polymer materials. In line with the requirements of Hebei Province’s 12th Five-Year Plan, Xuyang Group is committed to turning the Cangzhou industrial park into a domestic \"new materials industry hub\". The Cangzhou Xuyang Caprolactam Integration Project is a provincial and municipal industrial support project. It has been included in Hebei Province’s coastal development plan as well as Cangzhou City’s 12th Five-Year Plan. The project is designed to have an annual production capacity of 400,000 tons of caprolactam, and will be constructed in two phases.
