【Ten Years of Rapid Development in Chemical Equipment】The largest full-density polyethylene production facility in China from 1974 to 2022
Thread Content
Witnessing the decade-long rapid development of chemical processing equipment, we celebrate the prosperity and strength of modern China. Greater participation makes things more exciting; with you here, Haichuan becomes even better. This is just a modest contribution to spark further discussion – we welcome everyone to actively engage in forums and exchanges, with rewards for those who leave replies. Discussion is encouraged! ------------------------------------------------– On June 27, 2022, a ceremony was held on-site at the Guangdong Petrochemical plant to sign the completion certificate for the full-density polyethylene production facility. This marked the official entry into the preparation phase for operation of this facility, which has the largest production capacity of its kind in China and is part of the 800,000 tons per year full-density polyethylene production project under the general contracting of Daqing Petrochemical Engineering Co., Ltd. Guangdong Petrochemical’s full-density polyethylene plant is currently the largest single-unit production facility of its kind in China. It features a two-line design as well as a remote granulation system, which is the first of its kind among similar plants within the China National Petroleum Corporation’s network.
The plant adopts Univation’s UNIPOL PE process technology and is operated using a single-reactor gas-phase fluidized bed process; it is characterized by numerous construction steps, high technical complexity, and a high degree of automation. The project covers an area of approximately 58,000 square meters, with a total investment of around 1.76 billion RMB. Using ethylene, butene-1, and other materials as primary raw materials, this facility is capable of producing 15 different types of products, including LLD films, MCN films, LLD injection-molded products, HD injection-molded products, filaments, HD blow-molded products, HD films, and HD pipes, all made from LLDPE and HDPE polyethylene (pellet) resins.
Construction began on September 14, 2020； On November 7, 2020, the pile foundation work was completed ；
November 15, 2020: Project commencement for civil engineering works；
On April 11, 2021, the civil engineering underground works were completed；
