The newly introduced high-temperature and high-pressure hydraulic turbine energy-saving equipment by PetroChina Daqing Petrochemical Company's oil refinery has recently been successfully commissioned on the 1.2 million tons per year hydrocracking unit. This advanced system has proven highly effective, achieving an annual energy saving of 2.49 million kWh, which translates to a cost reduction of RMB 1.42 million in electricity expenses. As a result, the energy consumption of the unit has been reduced by 1.51%, significantly enhancing operational efficiency.
The equipment was sourced from Japan's Ebara Corporation and is specifically designed to recover pressure energy from the hydrocracking process. The turbine operates under a differential pressure of 11 MPa between the inlet and outlet, making it well-suited for handling the high-pressure and high-temperature conditions of the unit.
The 1.2 million tons per year hydrocracking unit was launched in August 2004 as part of Daqing Petrochemical Refinery’s modernization efforts. Originally, the hot high-pressure oil product was designed to exit at 230°C and 13 MPa. However, in the domestic petrochemical industry, there has long been a challenge in effectively recovering the pressure energy from such high-temperature and high-pressure media. This new system now provides a viable solution, marking a significant step forward in energy conservation and sustainable operations.
