Effect Evaluation of Energy Saving Measures for Diesel Hydrotreating Unit
Henan Fengli Petrochemical Co.,Ltd.has built a 0.6 Mt·a-1 mid-aromatics hydro-upgrading unit with a designed operating pressure of 13.4 MPa and a designed energy consumption of 20.29 kg standard oil per 1 t feedstock oil,which is higher than the energy consumption quota of similar units in Sinopec(12 kg standard oil per 1 t raw oil),in which electricity consumption accounts for 60%of the total energy consumption of the device.The device achieves the purpose of saving energy and reducing consumption by using hot feed,adding a stepless regulation system to a new hydrogen compressor,adding a stepless regulation system to a circulating hydrogen compressor,and adding a frequency converter to the high-pressure amine pump.Good economic benefits have been obtained.
