The Tarim Oil Field has built the largest ethane recovery unit of its kind in China
Thread Content
At 5 p.m. on May 28, encouraging news came from the construction site of the natural gas ethane recovery project at the Tarim Oil Field: the project was successfully completed, entering the final stages of preparation for operation, which lays a solid foundation for its commissioning on June 30. The natural gas ethane recovery project at the Tarim Oil Field involves expanding the ethane recovery facilities on the basis of existing light hydrocarbon deep recovery systems, in order to supply high-quality ethane as raw material for the ethylene production projects at the Dushanbe Petrochemical and Tarim Petrochemical subsidiaries. The ethane recovery plant is designed to handle 10 billion cubic meters of natural gas per year, with each unit having a capacity of 5 billion cubic meters per year; it is the largest ethane recovery unit of its kind in China. Once the project is put into operation, it will produce 762,000 tons of ethane, 366,300 tons of liquefied gas, and 74,700 tons of stabilized light hydrocarbons each year. The total annual output of liquid hydrocarbons will be 1.203 million tons. The project offers good economic prospects and is set to become a new \"engine\" for economic growth in the Tarim Oil Field; it holds great significance for building a world-class modern oil and gas field as well as promoting local economic development.
The Changqing Oilfield Shanggu Natural Gas Processing Plant project is currently the first large-scale ethane recovery project in China, and it represents a key initiative for the group’s upstream enterprises to improve efficiency and achieve transformational development. Leveraging the natural gas resources of the Changqing Shanggu gas reservoir, this project is designed to process 20 billion cubic meters of natural gas per year, with an annual production of 1.502 million tons of ethane, liquefied petroleum gas, and stable light hydrocarbons.
For the first time in China, this project employs a natural gas C2+ recovery process that combines \"mixed refrigerant pre-cooling + expansion refrigeration + dual-gas subcooling\"; it possesses complete independent intellectual property rights, filling the gap in the construction and technical application of natural gas ethane recovery facilities in the country； The construction model of a \"digital factory for the entire life cycle\" for large-scale facilities was first proposed at the Changqing Oilfield, enabling digital and intelligent management across the entire process from design, procurement, construction to operation and maintenance ； For the first time in the Changqing Oilfield, the world’s most advanced SP3D 3D plant design technology was adopted, enabling efficient collaborative design among various disciplines and facilitating construction as well as production operation management.
The Shanggu Natural Gas Processing Plant project of Changqing Oilfield is located in Sijiahaize Village, Qinhe Town, Yuyang District, covering an area of 846 mu. It is the largest single-project investment undertaken by Changqing Oilfield to date. The plant is designed to produce 1.0527 million tons of ethane, 356,300 tons of liquefied petroleum gas, and 93,000 tons of stabilized light hydrocarbons per year. Utilizing the natural gas reserves from the Paleozoic era in Changqing Oilfield, this plant employs deep-cold separation technology to extract components such as ethane from natural gas. It can process 20 billion cubic meters of natural gas per year, yielding a total of 1.502 million tons of ethane, liquefied petroleum gas, and stabilized light hydrocarbons. This project plays a significant role in enhancing energy production capacity, upgrading the industrial chain, and promoting regional economic development. At the same time, it will be implemented in parallel with Lanzhou Petrochemical’s ethane-to-ethylene project and constructed on an integrated basis; once operations begin normally, the products can be directly supplied to the ethylene plant as raw materials. The annual sales revenue is expected to reach 4.58 billion yuan, while taxes paid to Yulin City will amount to around 500 million yuan. This will further enrich the product structure of Yulin’s energy industry and help accelerate the city’s progress toward green, intensive, and high-quality development.
Are you sure they will start production on June 30?
