Description
technical field [0001] The invention relates to the field of petrochemical technology, in particular to a method and device for obtaining energy efficiency of an atmospheric and vacuum device. Background technique [0002] Atmospheric and vacuum devices are the general term for two devices, atmospheric distillation and vacuum distillation. Because the two devices are usually set together, they are called atmospheric and vacuum devices. The main energy forms of atmospheric and vacuum devices are heat, steam, and flow energy, among which heat, work, and steam are converted from electricity and fuel (heating furnace, pump, etc.). After the energy enters the fractionation tower through the conversion equipment, it completes the process together with the energy recovery system, part of it enters the product, and part of it enters the energy recovery system. [0003] In the prior art, in the process of analyzing the energy efficiency of atmospheric and vacuum devices, it is usual...
