Hangjin Jinxī Chlor-Alkali Chemicals has obtained a patent for a polymerization reactor with high-efficiency heat exchange capabilities, which significantly improves heat exchange efficiency. According to a report from Finance World on July 25, 2025, information from the Intellectual Property Office shows that Hangjin Jinxī Chlor-Alkali Chemicals Co., Ltd. has been granted a patent titled “Polymerization Reactor with High-Efficiency Heat Exchange Functions,” with the approval number CN223144703U; the application was submitted in November 2024. The patent abstract indicates that this utility model relates to a polymerization reactor with high-efficiency heat exchange capabilities, comprising a reactor body, a stirring mechanism, and a heat exchange jacket. A discharge pipe is located at the bottom of the reactor body. The key technical features are as follows: a heat exchange box is fixed to the lower exterior side of the reactor body using supports; the heat exchange box contains heat exchange pipelines with multiple bends. The discharge pipe has a branch, and the end of this branch is connected to the inlet of said heat exchange pipelines via flanges. An elevation pump is fixed to the upper exterior side of the reactor body, above the heat exchange box, using small supports; the inlet pipeline of the elevation pump is connected to the outlet pipeline of the heat exchange pipelines through flanges. A return pipe is fixed to the side of the top of the reactor body, and an air-cooling pipeline is arranged between the outer end of this return pipe and the outlet pipeline of the elevation pump. Multiple air-cooling fins are installed at intervals along the outer wall of said air-cooling pipeline. The top of the heat exchange box has a cooling water outlet, while its bottom has a cooling water inlet. According to Tianyancha, Hangjin Jinxi Chlor-alkali Chemical Co., Ltd. was established in 2020 and is located in Huludao City. It is a company that focuses on the processing of petroleum, coal, and other fuels. The registered capital of the enterprise is 500 million RMB.
