November 24, Zhenhai Refining & Chemical Refining three seven hydrogenation unit successfully cast raw material pump hydraulic turbine HT401, according to observation and calculation, after the use of hydraulic turbine, the raw material pump motor current from the previous 185 ampere down to 130 Ampere. Equivalent to reducing power consumption per hour, 514 kilowatt hours, is expected to save electricity costs 230 million per year, energy saving effect is obvious.
The hydraulic turbine is high pressure liquid medium pressure energy can be converted to mechanical energy equipment, energy recovery is converted to mechanical energy used to drive the oil pump P402A, in order to achieve energy-saving purposes. For a long time, due to mechanical seal leakage and lubrication pressure Low problems, has not reached the conditions of employment. The Ministry of continued tracking and coordination of foreign experts to guide the scene, after a long-term continuous site exploration and exploration, and ultimately reached the trial conditions put into use.
In order to ensure that the turbine can be put into operation smoothly and once, the operation department is meticulously organized, and the process, lubricating oil system, cooling water system, mechanical seal system and instrument are all strictly carried out in strict accordance with the operation rules and the technical requirements of the equipment operation method One by one confirmed, in accordance with the hydraulic turbine irrigation and heating requirements fully preheated, to ensure the full reach of the conditions of employment.
At present, the cumulative total energy consumption of the seven hydrogenation units is 6.81 kg of standard oil / ton, which is much lower than the designed value of 11.24 kg of standard oil / ton, and the investment of this measure will add new color to the energy-saving work of the unit.
