On November 15, a grand ceremony was held at the construction site to mark the mechanical completion of the core facility for the fine chemicals and raw materials project of Northern Huajin United Petrochemical Co., Ltd., which is being built under the Huajin Project: the 736,000/700,000 tons per year ethylbenzene/styrene plant. This marks the successful completion of the main construction work for this facility, including civil works, structure, equipment, and process pipelines. It now enters the stages of \"three inspections and four determinations\", system purging, pressure testing, and joint commissioning, representing a key step toward achieving high-standard project completion and operational start-up on schedule. As one of the key units operated by the company at Huajin APM, the 736,000/700,000 tons per year ethylbenzene/styrene plant utilizes process technology from the American company Badger, and it is considered large-scale among plants of its type. The construction process for this device requires strict standards, high technical specifications, and intensive cross-task operations. Since the project began, the project team has always adhered to the management philosophy of \"quality first, safety first, scientific organization, and efficient construction.\" Overcoming various challenges such as severe cold weather and shortages of materials, they coordinated resources effectively, worked day and night, and successfully completed the installation of 7,500 tons of steel structures, welded over 260,000 inches of process pipelines, and lifted 23 large-scale towers and reactors. All key milestones were met on schedule, with a first-pass welding success rate of 98.5%. The team was praised multiple times by the client and the general contractor.
