Analysis and evaluation of heat integration schemes for crude oil distillation unit
摘要
Abstract
According to the characteristics of the energy use of the crude oil distillation unit,the heat integration scheme of the crude oil distillation unit was analyzed and evaluated with the help of the pinch analysis method,Using the proposed thermal integration effective value evaluation index,this paper explored the optimization strategy for heat integration of the crude oil distillation unit based on pinch point analysis,and studied the application of this method in different heat integration schemes such as heat integration below the pinch point,across the pinch point and above the pinch point.The proposed method could be used to determine whether the heat integration scheme of crude oil distillation units was effective,and effectively guided the heat integration between crude distillation units in refining enterprises.The cases study showed that the effective value of heat integration was only 7%in the high temperature hot water heat integration scheme cross pinch point.The effective values of heat integration for the catalytic slurry A and B heat integration scheme above the pinch point,where the slurry A and B had same initial and target temperature and different heat,were 100%and 60%,reducing the thermal utility load of the plant by about 25%and 30%,respectively.关键词
