Abstract


Crude oil distillation unit energy consumption in one of the devices in the refinery , accounting for about 25% of the total energy consumption of the refinery to 30 % . Coking waste oil processing unit , a special micro - atmospheric and vacuum distillation unit , compared to its energy consumption and energy consumption of the crude oil distillation unit is 4 to 5 times higher , thus reducing the energy consumption of the device has an extremely important significance , energy-saving technology can play a role in this particular device . Coking sewage oil processing device status quo of Jinzhou Petrochemical Company analysis to identify high energy consumption of the device where the bottleneck problem . First for demulsifiers the coking waste oil pretreatment process use limitations , to carry out the the new demulsifier screening and research work , and the the new demulsifier and the best operating conditions applied to the dewatering operation , saving energy consumption of steam . Followed by the furnace exhaust gas temperature is too high , redesigned to increase the atmospheric convection section furnace , reducing the exhaust gas temperature . Redesigned heat exchanger network , improve feedstock oil heat exchanger final temperature . Practice has proved that the application of energy-saving technologies , to achieve the energy-saving effect .
