PetroChina Company Limited has officially commissioned its first hydraulic turbine direct-drive pump at the third-phase expansion project of the Xushen 9 natural gas purification plant in Daqing Oilfield. This innovative technology is set to cut overall facility energy consumption by more than 30%, while saving roughly 4 million cubic meters of fuel gas annually, carving out a fresh pathway for energy-efficient and carbon-reducing treatment of high-carbon natural gas.
The research team rolled out the hydraulic turbine direct-drive pump system to tackle persistent industry hurdles, such as the heavy energy draw of decarbonization processes in high-carbon gas streams and the lack of equipment stability during operation. By converting the pressure energy of high-pressure rich amine solution directly into pumping power, the novel approach delivers notable energy savings. It also streamlines the equipment layout, trims the number of potential failure points, and boosts both the reliability and safety of system operations, underpinning greener oil and gas production with cutting-edge technology. The successful deployment offers valuable insights for revamping similar existing units and designing new projects in the future.
