In 2026, the 25th National \"Safety Production Month\" will be observed – with everyone emphasizing safety and knowing how to respond in emergency situations, as well as working to identify and address potential risks and hazards. On June 8th, the Environmental Protection Bureau of Xuwu New Area issued a public notice regarding the acceptance of the environmental impact assessment for the oxygen interconnection upgrade project carried out by Shenghong Refining & Chemicals (Lianyungang) Co., Ltd., which is part of the Shenghong Petrochemical Group. Total investment: 33 million. Scale and scope of construction: An additional DN300 pipeline will be added to the medium-pressure oxygen pipeline in the refining and chemical plant complex, leading to the Serbon plant complex; meanwhile, another pipeline will be added to the high-pressure oxygen pipeline in the refining and chemical plant complex to connect with the medium-pressure oxygen pipeline. This arrangement enables oxygen to be shared across the group, thereby achieving energy savings, reduced consumption, and improved operational efficiency. Project background: At present, the air separation systems in the various subsidiaries of Shenghong Petrochemical Industry Group are operating normally. However, due to the independent operation of these systems and the design redundancy features, they result in high energy consumption. To meet the needs of the group’s future construction and planned projects (such as Phase 3 of PTA production and oil reduction and upgrading projects), it is necessary to optimize the utilization of existing oxygen resources in order to reduce operating costs.
