Abstract: Based on three-link energy structural model and plant calibration data，energy balance test and process energy utilization analysis were carried out for two typical hydrocracking plants for producing heavy naphtha and middle distillates respectively. The effects of process configuration，catalyst，equipment，technology and efficiency on energy utilization level were analyzed in detail. Energy-saving approaches were recommended from the aspects of plant design and operation.
