Successful Primary Power Supply to the Transformer Substation of Cangzhou Xuyang Hydrogen Peroxide Plant / Author/Source: Gasification World / Date: April 10, 2022 / Clicks: 10. On April 6, the primary power supply to the transformer substation of the Cangzhou Xuyang Hydrogen Peroxide plant, constructed by Shiliu Hua Jian, was successfully established. This successful power supply marks the official entry of the plant into the stage of individual unit testing, creating favorable conditions for the subsequent completion of the project. It is reported that the total investment in this project amounts to 4.5 billion yuan. The main facilities to be built include a caprolactam plant with an annual production capacity of 300,000 tons, a cyclohexane plant with an annual capacity of 270,000 tons, a hydrogen peroxide plant with an annual output of 343,000 tons (35%), an ammonium sulfate plant with an annual capacity of 450,000 tons, a hydrogen production facility using lignite, as well as a synthetic ammonia plant with an annual capacity of 300,000 tons, along with supporting raw material and utility facilities. This project utilizes world-class manufacturing technologies, featuring high production capacity per production line and low investment costs. It offers 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 lactam produced, generates less sulfuric acid as a by-product, and ensures excellent product quality; all its parameters far exceed the relevant standards. It can be applied to various types of textiles that require fine weaving or high-speed spinning, as well as to special engineering products, thus laying a solid foundation for the development of a new polyamide materials industry in the Bohai New Area in the future. Project Overview: The caprolactam expansion project of Cangzhou Xuyang Chemical Co., Ltd. involves a total investment of 4.5 billion yuan. It includes the construction of a caprolactam production facility with an annual capacity of 300,000 tons, a ** production facility with an annual capacity of 270,000 tons, a hydrogen peroxide production facility with an annual capacity of 343,000 tons (35%), a sulfuric acid anhydride production facility with an annual capacity of 450,000 tons, a hydrogen production facility using lignite, as well as a synthetic ammonia production facility with an annual capacity of 300,000 tons. Additionally, supporting raw material facilities and utility systems will be built. Upon completion of the project, the company’s annual sales revenue could reach 10 billion yuan, with total profits and taxes amounting to 2 billion yuan; it could also create 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 lignite-to-hydrogen plant with a capacity of 80,000 Nm3/h, and a hydrogen peroxide plant with an annual capacity of 120,000 tons (equivalent to 100% wt). The project utilizes 3 Jinhua Type 3.0 furnaces. The raw material for the PSA hydrogen production unit in Cangzhou Xuyang Chemical Co., Ltd.’s caprolactam expansion project is hydrogen produced from semi-coke; 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 output volume of the product gas is 55,000 Nm3/h. 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. The scope of the first-phase construction includes: 200,000 tons per year of **, 200,000 tons per year of caprolactam, as well as related supporting projects and auxiliary facilities. The second-phase construction includes: 200,000 tons per year of **, 200,000 tons per year of caprolactam, and 120,000 tons per year of nylon-6, etc. The first phase of the project, with a capacity of 100,000 tons per year, was put into operation at the end of 2013; the 100,000 tons per year caprolactam production facility started operating in June 2014.
