Hongbaoli’s propylene oxide project is set to begin trial production by the end of the year 2025-03-17. The technological upgrade project for Hongbaoli’s propylene oxide production uses the isopropylbenzene process, and trial production is scheduled to start by the end of the year. The propylene oxide produced by this project will be used as a raw material for the production of polyether and isopropanolamine products, primarily for use within the internal supply chain. Currently, global propylene oxide production methods include various approaches such as the chlorohydrin method and the co-oxidation method, and these different processes vary in terms of cost and environmental impact. On April 15, 2022, the 17th meeting of the ninth board of directors of the company approved the \"Resolution on Matters Concerning the Company\" ； To meet its own development needs and achieve economies of scale, it has agreed to undertake the “Taixing Chemical Company Propylene Oxide Expansion Project”. It has decided to upgrade the existing propylene oxide production facilities by introducing automation, digitalization, and intelligent technologies, thereby enhancing the integration of information technology and industrial processes and optimizing key manufacturing steps. The annual production capacity of the propylene oxide facility is to be increased from 100,000 tons to 250,000 tons. This project aims to become a model for the new CHPPO process for producing propylene oxide in China, with a construction period of 18 months. During the process of submitting the project for government approval, it was delayed for some time due to the local government’s policy on dual control of energy consumption, which resulted in insufficient energy metrics for the project. Given the necessity and urgency of technical upgrades for this project, and after consulting with the relevant local government authorities, the company adjusted the expansion plan for the project. In line with the energy requirements, the expansion is to be carried out in phases: the first step involves upgrading the facility to a capacity of 160,000 tons, and the original planned investment amounts have been adjusted based on the outcomes of the process optimization efforts. The comprehensive technical renovation project for 160,000 tons per year of propylene oxide was filed with the relevant government authorities in March 2023. Hongbaoli Group Co., Ltd. was founded in 1987; it is a chemical new materials company that focuses on propylene oxide, as well as polyurethanes, alcohols, amines, and their derivatives. In recent years, the group has focused on using innovation to boost industrial development and improve quality, and has been successively recognized as a **-level manufacturing industry champion as well as a company characterized by specialization, excellence, and uniqueness. In direct competition, Red Baoli ranks at the top in the two sub-sectors of rigid polyether foam for refrigerators and isopropylamine. The group company was listed on the Shenzhen Stock Exchange in 2007. It currently possesses a world-leading R&D center and industrial base for polyurethane rigid foam polyether, a R&D center and industrial base for alcohol amine products with core competitive advantages, a specialized industrial base for highly flame-retardant polyurethane insulation panels, as well as an industrial base for producing propylene oxide and its derivatives via the CHPPO process.
