Thread Content

Looking at the development of chemical technology over the past decade, we praise the prosperity and strength of modern China. By sharing our insights, we encourage more people to participate and make the discussion more lively. Hainan Chemical Industry becomes even better with your involvement. [A Decade of Progress in Chemical Equipment] – Continuous updates and summaries are available; feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html. It is important to enhance quality awareness and promote high-quality development. ----------------------------------------- On October 8th, the inauguration ceremony for the 270,000/600,000 tons per year propylene oxide/styrene (including ethylbenzene) production facility (referred to as the “POSM facility”) as part of Guangxi’s petrochemical integration and transformation project was held at Qinzhou Port. It is understood that the POSM unit of the Guangxi Petrochemical project is the first of its kind in China Petroleum to be designed, purchased, and constructed independently. This unit constitutes an important part of the transformation and upgrading project at Guangxi Petrochemical; it enhances the range of downstream products and enriches the industrial chain, while also holding significant significance for the overall implementation of the project. The POSM plant has a capacity of 270,000 tons per year for propylene oxide and 600,000 tons per year for styrene. Its total floor area is 151,435 square meters. It consists of various units including those for ethylbenzene processing, peroxide treatment, epoxidation, PO purification, phenylethanol dehydration, styrene purification, hydrogenation, environmental protection systems, utility and auxiliary facilities, furnace areas, plant tank areas, on-site cabinet rooms, and plant substations. It is understood that the Guangxi Petrochemical Integration and Transformation Project is a major project under the petrochemical industry development plan. It is also a strategic initiative by China National Petroleum Corporation aimed at shifting focus from oil production to chemical production in order to adjust the industry structure. This project holds great significance for reshaping the petrochemical industry and its structural layout in Guangxi and Qinzhou cities, enhancing the scale and concentration of the petrochemical industry, and promoting the optimization and upgrading of related processing industries. The POSM unit of the Guangxi Petrochemical project is the first of its kind in China Petroleum that has been independently designed, purchased, and constructed; therefore, completing the construction of this POSM unit is of great significance.
