HAZOP, LOPA, and SIL classification meetings for Jinmei Hengsheng’s “40·60” project were held. Author/Source: Jiangsu Jinmei Hengsheng Chemical Co., Ltd. Date: 2020-06-19. Views: 12. The HAZOP, LOPA, and SIL classification meetings for Jinmei Hengsheng’s “40·60” project were held via video conference from May 25 to June 20, with participants including Jinmei Hengsheng, Donghua Design Institute, and various manufacturers of process packages. HAZOP analysis is a structured analytical method used to identify design flaws, process hazards, and operational issues; its essence lies in analyzing process diagrams and operating procedures through a series of meetings. During the meeting, an analysis team composed of various specialists systematically studied each unit (i.e., analysis node) in a prescribed manner, analyzing the hazards and operational issues resulting from deviations from the designed process conditions. The HAZOP analysis team examines each process unit or operational step to identify deviations that pose potential hazards. These deviations are brought out using trigger words; one purpose of using these trigger words is to ensure that all deviations in process parameters are analyzed, along with their possible causes, consequences, and existing safety measures. Additionally, recommended safety measures are proposed. The purpose of a HAZOP analysis is to identify hazards present in the process production or operation, as well as any unacceptable risk situations. Using HAZOP during the basic design phase of a project means identifying potential hazards in the design, operating procedures, and equipment as early as possible in the project implementation process, detecting problems in the basic design, and correcting them during the detailed design phase – an approach that helps to save costs.
On August 19, 2019, the groundbreaking ceremony for the Jiangsu Jinmei Hengsheng New Materials Industrial Park project was held on the banks of the beautiful Xindai River in Xinyi City, Jiangsu Province. This not only marks a solid step forward for Jinmei Hengsheng in its transformation and development, but also opens a new chapter in the high-quality development of the industries in Xinyi. Key leaders from Xuzhou City, Jinmei Group, and Xinyi City attended the event.

Jiangsu Jinmei Hengsheng New Materials Industrial Park is a specialized park designed to undertake the relocation and technological upgrading projects of Hengsheng Chemical’s old factory site. With a total planned investment of 5.75 billion yuan, it will leverage the capital, technology, and equipment strengths of Jinmei Group as well as companies such as Cabot from the Netherlands, Topsoe from Denmark, and Cassali from Switzerland to develop clean energy products and new materials that represent the future direction of the chemical industry. The park aims to become a first-class modern coal chemical industrial park in China, achieving low emissions, low energy consumption, and high efficiency, while serving as a model for the transformation and development of traditional industries. Upon completion of the project, it is expected to generate annual sales revenue of 5.42 billion yuan and profits and taxes of 960 million yuan.
The first phase of this project includes facilities for producing 400,000 tons of synthetic ammonia, 600,000 tons of urea, 47,800 tons of sulfuric acid, as well as cogeneration units. Once operational, these facilities will generate revenue of 2 billion yuan and profits and taxes amounting to 460 million yuan. The second phase involves facilities for producing 200,000 tons of ethylene glycol, 150,000 tons of methanol, dimethyl carbonate, and polyols. Upon completion and operation, these facilities will add an annual revenue of 2.82 billion yuan and profits and taxes of 500 million yuan.
Phase 1 adopts advanced processes such as the pulverized coal gas fluidized bed pressurized gasification process (with 2 gasifiers of a total volume of 89 m3 built in Phase 1 to meet the gas demand for ethylene glycol gasification in Phase 2), sulfur-resistant wide-temperature shift reaction, low-temperature methanol washing for desulfurization and decarbonization, liquid nitrogen washing (yielding sulfuric acid as a by-product), three-bed heat-exchange type axial-radial energy-saving ammonia synthesis, improved carbon dioxide stripping-based urea synthesis, large-grain urea, high-tower compound fertilizers, cryogenic oxygen production, and liquid oxygen internal compression air separation. In the second phase, dry coal powder fluidized-bed pressurized gasification, sulfur-resistant shift reaction, low-temperature methanol washing for desulfurization and decarburization, pressure swing adsorption for H2/CO separation, methanol carbonylation to produce dimethyl oxalate, and hydrogenation of dimethyl oxalate to produce ethylene glycol are employed.
Upon completion of the project, clean energy products and new material products will be developed and produced without any increase in coal consumption, generating annual sales revenue of 5.42 billion yuan and profits and taxes of 960 million yuan. By developing clean energy products and new materials that represent the future direction of the chemical industry, efforts are being made to create a first-class modern coal chemical industrial park in China, one that features low emissions, low energy consumption, and high efficiency, thereby serving as a model for the transformation and development of traditional industries.
Jiangsu Jinmei Hengsheng New Materials Industrial Park is a first-class modern new coal chemical industry park. Upon completion of the project, clean energy products such as hydrogen, as well as new material products like polycarbonate and nylon 66, will be developed and produced without increasing coal consumption.
