Tender for foundation engineering design of 1 million tons/year ethylene plant! 2025-08-05 On August 4, an auction notice was issued for Bid Section 1 of the foundation engineering design for 7 units including the ethylene plant, as part of the 1 million tons per year ethylene refining and chemical processing integrated project in the Yueyang area of Hunan Petrochemical. Project Overview and Scope of Bidding: Construction location: Hunan Yueyang Green Chemical High-tech Industrial Development Zone, Yunxi District, Yueyang City, Hunan Province. Bid section division: 1 bid section. Estimated contract value for this bid section: 160.28 million yuan (excluding tax). Scope of the bidding: Foundation engineering design and related technical services for 7 units including ethylene, as well as the supporting facilities, for the 1 million tons per year ethylene refining and chemical integration project in the Yueyang area of Hunan Petrochemical. (1) A total of 7 process units: an ethylene plant with a capacity of 1 million tons per year, a butadiene extraction plant with a capacity of 150,000 tons per year, a pyrolysis gasoline hydrogenation plant with a capacity of 500,000 tons per year, an aromatic extraction plant with a capacity of 300,000 tons per year, an aromatic to benzene conversion plant with a capacity of 300,000 tons per year, MTBE/butene-1 plants with capacities of 100,000/40,000 tons per year, and an LLDPE plant with a capacity of 400,000 tons per year ； (2) Supporting storage and transportation facilities in the Changling North New Area: 1 ethylene cryogenic tank bank, with each tank having a capacity of 3×104 m3 ； (3) Changling North New Area process system (maximum design pressure: 4.8 MpaG) and thermal pipeline network ； (4) Torch system ； (5) The plant’s power supply system and road lighting, as well as the plant’s electrical automation system, etc ； (6) Auxiliary facilities: central control room, plant-wide telecommunications system, plant-wide information system, waste heat recovery and refrigeration station, etc ； (7) Safety and environmental protection facilities: waste gas and liquid treatment systems, waste alkali oxidation facilities, etc. The Yueyang ethylene project has a total investment of 35.68 billion yuan, making it the largest industrial project in Hunan to date in terms of investment amount. It consists of two components: an ethylene production facility with an annual capacity of 1 million tons, and upgrades to the refining facilities. The main construction components of the ethylene project include: the construction of a new ethylene plant with an annual capacity of 1 million tons, along with 14 other chemical processing units downstream. Ten of these chemical processing units are to be built in the Changling New Area; they include the 1-million-ton-per-year ethylene plant, a 500,000-ton-per-year hydroprocessing unit for cracked gasoline, a 300,000-ton-per-year aromatic extraction unit, a 300,000-ton-per-year unit for producing benzene from aromatics, a 150,000-ton-per-year butadiene extraction unit, a 20,000-ton-per-year styrene extraction unit, a 300,000-ton-per-year EVA plant, a 400,000-ton-per-year high-density polyethylene (HDPE) plant, a 400,000-ton-per-year linear low-density polyethylene (LLDPE) plant, and 10/40,000-ton-per-year MTBE/butene-1 plants ； The remaining four units of the main project are being newly constructed in the old Baling area. These include a 150,000-ton/year C5 separation unit, a 300,000-ton/year propylene oxide (CHPPO) unit, a 220,000/130,000-ton/year phenol/** unit, and a 240,000-ton/year bisphenol A unit. These units complement the existing epoxy resin and synthetic rubber facilities at the original Baling Petrochemical Complex. Construct the necessary storage and transportation facilities, utility systems, and auxiliary installations. The main construction components of the refinery upgrading project include: the construction of a new hydrocracking complex with an annual capacity of 3 million tons, a sulfur recovery unit with an annual capacity of 60,000 tons, and a solvent deasphalting unit with an annual capacity of 1 million tons. Unit 2 of the atmospheric and vacuum distillation complex will be upgraded to an annual capacity of 10 million tons, while one 3.5-million-ton-per-year refining unit each at the original Changling Refining and the original Baling Petrochemical plants will be shut down. This project primarily utilizes green and low-carbon process technologies owned by Sinopec and considered industry-leading; the advantages in raw materials, technology, and products work together to complete the industrial chain in the Yueyang area, ranging from crude oil processing to modern specialty chemicals, thereby creating an industrial framework that includes \"clean petroleum products + modern chemicals + new materials\". Once the project is completed and put into operation, it will drive downstream investments of over 150 billion yuan, playing a significant role in promoting the development of the central region and the Yangtze River Economic Belt, as well as helping Hunan Province to become a core hub for a modern petrochemical industry worth trillions of yuan.
