Recently, the 711 Institute of China State Shipbuilding Corporation won all four bids for process screw compressor units in the fine chemicals and raw materials project carried out by Northern Huajin United Petrochemical Co., Ltd. (hereinafter referred to as “Northern Huajin United Petrochemical”), with a total value exceeding 170 million yuan. The Beifang Huajin United Petrochemical Fine Chemicals and Raw Materials Project mainly includes 15 million tons per year of oil refining capacity, 1.65 million tons per year of ethylene production, and 2 million tons per year of p-xylene production. This project is a key development project aimed at **serving the new round of the Northeast Revitalization Strategy and promoting the growth, strengthening, and expansion of the oil and petrochemical sector. The equipment awarded to 711 includes various units such as MVR heat pump units for the propylene oxide plant, exhaust gas compressors for the styrene plant, PSA exhaust gas compressors for the aromatic compounds complex, and compressors for ethane-rich and ethylene-rich gases in the carbon dioxide recovery unit. Among them, the MVR heat pump unit in the propylene oxide plant can improve the steam utilization efficiency of the plant, thereby effectively reducing the operating costs of the user’s facility ； The PSA exhaust gas compression unit replaces traditional reciprocating models; it not only significantly reduces customers’ initial investment and subsequent equipment maintenance costs, but also increases the continuous operation time of the system by at least 5 times. Since the 1990s, 711 has developed a series of process compressors, flares, boilers and other equipment for its clients based on their actual operational requirements, establishing a sound cooperative relationship built on mutual benefit. In the future, 711 Institute will continue to be customer-oriented, further investing in technological innovation to provide customers with satisfactory solutions for energy and power equipment systems.
