The 400,000 tons per year aromatic extraction unit of Guangxi Petrochemical’s integration and transformation project was successfully commissioned
Thread Content
On April 20, the 400,000-ton/year aromatic extraction unit of Guangxi Petrochemical’s integration and transformation project was successfully handed over; this was the first production unit of this project to be delivered by Huanqiu East China Company. As one of the key production units in the project, the aromatic extraction unit obtains C6–C8 hydrogenated fractions from the gasoline hydrogenation unit via an ethylene cracking unit. It produces benzene, toluene, xylene, raffinate oil, and the heavy components at the bottom of the xylene column, providing high-quality raw materials for downstream chemical plants. This unit features a simple process, good adaptability to various raw materials, high solvent selectivity, and low energy consumption. The Guangxi Petrochemical Integration and Transformation Project is located in the Jingu area of the Petrochemical Park within the Qinzhou Port Economic and Technological Development Zone. With a total investment of around 30.5 billion yuan, it includes the construction of 14 chemical processing units, such as an ethylene cracking unit with an annual capacity of 1.2 million tons, as well as 2 refining units for diesel adsorption and dearomatization with an annual capacity of 2 million tons. The project also involves the construction or renovation of certain refining units, along with corresponding utility systems, storage and transportation facilities, and auxiliary production equipment. It will primarily produce products such as polyethylene, polypropylene, synthetic rubber, and ethylene-vinyl acetate copolymer (EVA). Completion of the project is expected by 2025.

Since commencement on November 20, 2023, the project team has always adhered to the principle that \"the success of the client’s project is what the world seeks,\" ensuring that everything is done to serve the project. By leveraging the advantages of EPC general contracting management and coordinating design, procurement, and construction processes in a scientific manner, while actively implementing the requirements for \"six modernizations,\" it was possible to achieve the goals regarding project quality, safety, and schedule control. In total, 2,288 cubic meters of concrete were poured, 1,485 tons of steel structures were installed, 108 pieces of mechanical and electrical equipment were installed, 78,000 inches of process pipelines were welded, and 108 kilometers of cables were laid. The project department adheres to the guidance of Party building; under the supervision of the Party Working Committee for the company’s Guangxi Petrochemical project, the on-site Party branch carries out themed educational activities aimed at \"changing mindsets, fostering innovation, strengthening management, and striving for excellence.\" By taking into account the actual conditions of the plant construction, it continuously reinforces management responsibilities at all levels to drive the progress of the project. During that period, Huanyu East China Company and the seventh construction company of the engineering construction firm formed a joint Party member task force. Party members and cadres stepped forward as pioneers in overcoming difficulties, leading all those involved in the project to get past challenges such as the long rainy seasons, extreme heat in summer, and frequent typhoons. They managed to resolve issues that hindered the project’s progress in a timely manner. Excellent results were achieved in terms of on-site quality control, safety management, and civilized construction; the project team was awarded several times the title of “Quality Management Red List Unit” by the project owner, as well as “Red List Nominee for HSE Safety Performance” and “Outstanding Unit in Civilized Construction”.
