Hengli Refining & Chemical ensures completion of the entire coal oil integration process by March 20. Four days ago, on February 7, the high-pressure pipeline testing for the wax oil hydrogenation unit in Hengli (Dalian) Petrochemical’s 20 million tons per year refining & chemical integration project, which is being constructed by Sinopec Refining & Chemical Engineering Group’s Tenth Construction Company, was successfully completed, marking the entry of the pipeline testing phase of this project into its final stage. The high-pressure pipeline that passed the pressure testing successfully this time starts from the 3 main frameworks of the wax oil hydrogenation unit, passes through heating furnaces, 48 air coolers, and 18 high-pressure devices, and connects 3 reactors. In total, there are 7 sections subject to pressure testing, with a length of 13 kilometers. The total length of pipe welding involved is 80,000 inches, the maximum diameter of the pipes is 1,050 millimeters, the highest pressure applied during testing is 35 MPa, and the amount of water used for testing was as much as 2,600 tons. This is the largest high-pressure pipeline system that Shijian Company has ever constructed in its history. Starting from New Year’s Eve, the project team worked tirelessly for 48 hours straight, and the high-pressure pipelines of the paraffin oil hydrogenation unit passed the pressure testing on the first attempt, earning high praise from both the owner and the supervisor. As of February 10, the project team had already completed in advance all the construction milestones required by the client during the Spring Festival period. At present, the project team will, in line with the overall commissioning objectives for each area of Hengli (Dalian) Petrochemical, make every effort to complete the remaining pressure testing tasks on the process pipelines, ensuring that both wax oil hydrogenation units can be successfully commissioned on schedule. The Spring Festival period is a critical time for the full commissioning of Hengli’s 20 million tons per year integrated refining and chemical processing project; Chairman Chen Jianhua visited various plant areas to discuss plans for accelerating operations with the site managers and foreign engineers. All personnel from the main units of Hengli Refining & Chemical, along with more than 10,000 highly skilled workers dispatched by over 100 project construction units, are working at the front lines, going all out to ensure quality and efficiency while racing against time to make progress. At present, refining units such as atmospheric and vacuum distillation and light hydrocarbon recovery, as well as related facilities like coal-to-hydrogen production, are successfully producing products, with 8 of these products already being sold on the market. The distillation systems of various downstream units have been fully connected for oil circulation, and all distillation furnaces have been ignited and heated up ； The circulation pumps of the reaction systems in various hydrogenation units for downstream products such as naphtha, aviation fuel, lubricating oil, diesel, wax oil, and residue have all been started successfully on one attempt and are operating stably, while the reaction heating furnaces have all been ignited for drying. The various units are gradually and fully entering operation. It is expected that by the end of February or before March 20, the entire production process will be fully operational, enabling full-capacity production and operation of the entire refining facility.
