The construction of Daqing Petrochemical’s new 30,000-ton/year POE industrial demonstration plant has entered the installation phase
Thread Content
At 8:58 on January 5, the core equipment of Daqing Petrochemical Company’s new 30,000-ton/year POE industrial demonstration plant project – the octene distillation tower (C-4210) – was successfully lifted into place. The completion of this critical milestone marks the official transition of the project from the civil construction phase to the installation phase, laying a solid foundation for the further progress of the work. As the first major equipment lifting milestone for the POE project, the octene distillation tower being lifted this time has a diameter of 2.4 meters, a static weight of 30 tons, and a height of 60 meters. It is a core and critical piece of equipment in the entire plant system, and its successful installation marks a significant milestone in the project’s progress. Since the equipment arrived at the site on December 15, 2025, the project team has worked efficiently on the preliminary preparations, completing the entire process of installing the pipelines attached to the tower, various auxiliary components, and platform ladders, as well as carrying out insulation and anti-corrosion treatments, in just half a month. In the face of the extreme climate challenges posed by the severe cold and frequent snowstorms in the Daqing area during winter, the supervision team took the initiative to work closely with the construction units. They adopted an innovative winter construction method that combined insulated sheds with steam curing, thereby ensuring precise control over the temperature during key processes such as concrete pouring, and guaranteeing that the project quality met all regulatory requirements.

It is reported that the total investment for this project amounts to 1,158.06 million yuan. The main construction components include seven process production units and one utility unit, namely the raw material buffering and refining unit, the catalyst unloading and preparation unit, the polymerization and devolatilization unit, the monomer and solvent recovery unit, the extrusion granulation unit, the mixing unit, the packaging and finished product storage area, as well as the utility unit. Planned completion date: The completion of this project is scheduled by June 30, 2026, starting from the date the contract comes into effect. After more than a decade of technical research and development, the Petrochemical Research Institute of CNPC has overcome a series of engineering challenges related to rapid heat removal from reactors, stable polymerization control, deep devolatilization, and product granulation. It has built a \"thousand-ton per year experimental facility for high-end elastomers using the solution method,\" and developed 12 POE products for use in areas such as photovoltaic film, impact modification, foaming, and cables ； A 10,000-ton/year process package was designed to enable engineering implementation. This technological process successfully broke the technical monopoly held by foreign companies, achieving a comprehensive breakthrough for China National Petroleum Corporation in the field of POE new materials.
