According to Sinopec News Network (Wu Liwei), in recent days, the construction of the two wax oil hydrogenation units for Hengli (Dalian) Petrochemical’s 20 million tons per year integrated refining and petrochemical project, which is being carried out by the 10th Construction Company of Refining and Chemical Engineering, has entered the final stages. In the face of the severe cold weather in the Dalian area after New Year’s Day, all the employees working on the Dalian Hengli project for Shijian Company focused closely on the goal of starting up the paraffin hydrogenation unit by January 15th. They advanced the project by carrying out pressure testing on the process pipelines, and improved construction efficiency by optimizing the construction plan; as a result, the project progressed well. It is understood that since April 2018, the construction of the two wax oil hydrogenation units at Hengli (Dalian) Petrochemical has entered a full peak phase. During 9 months of intensive construction, the project team fully fulfilled the enterprise’s responsibilities regarding safety, eliminated major hazards, and prevented serious accidents, ensuring that safety, quality, and progress were always under control. Given the variety of material types used for the process pipelines in the wax oil hydrogenation unit undertaken by the project team, the large wall thicknesses, numerous welds, and the extremely high pressure levels, 15 different testing methods are required. These factors pose many challenges to the final pressure testing of the process pipelines. To accelerate the progress of pressure testing for the process pipelines, on January 5th, the project department established a team of 20 technicians to handle any remaining tasks. Braving temperatures well below zero degrees, they went straight to the construction site and conducted a thorough review of all the remaining 112 pressure testing tasks related to the process pipelines, in order to identify factors that were slowing down the testing process. They held meetings late at night to review the tasks remaining for that day, and they also calculated and analyzed the locations required for scaffolding as well as the inspection points needed for testing on the same day. At the same time, the project team assigned 10 quality inspectors to closely monitor all the lists of remaining tasks, ensuring that the relevant data was accurate before submitting it to the supervisors of the owner’s workshop and the testing units. This created favorable conditions for accelerating the testing process and improving the efficiency of pressure testing. At present, in accordance with the overall commissioning and feeding plan for the two wax oil hydrogenation units at Hengli (Dalian) Petrochemical, the project team is reorganizing the management personnel across various specialties to ensure that responsibilities are assigned to specific individuals, thereby making every effort to complete the pressure testing of the process pipelines and laying a solid foundation for the successful initial commissioning and feeding of the wax oil hydrogenation units.
