How to reduce the dry point of triple blended oil and increase the distillate yield before 300 degrees
Thread Content
Dear colleagues: Since the operation of our plant’s 75,000-ton per furnace and per tower continuous tar processing unit began, the dry point of the three-component mixture has remained around 320 degrees. The temperature at the second-stage oil outlet is 375, the temperature at the top of the second-stage evaporator is 355, the temperature at the top of the fractionation tower is 120, and it is around 302 at the bottom. There is no anthracene oil reflux at the top of the two-stage evaporator, and a small amount of superheated steam is added at the bottom of the tower. Please give me some advice! ! ! ! ! ! ! !
I’m not sure what the outlet temperature of the three-component mixture is; it might be possible to reduce the output volume of this mixture in order to lower its outlet temperature. It can reduce the dry point of the three-component mixture
