The effects of intensifying distillation on Daqing crude oil were determine d at different concentrations and distillation temperatures by simple distillati on and TBP distillation. The mechanisms of intensifying distillation of crude oi l by using different additives are discussed.The experimental results show that the types of additives, concentrations and distillation temperatures are main fa ctors which affect intensifying distillation of crude oil.The intensifying effe ct of the new activator developed in this work is better than that of the other additives.展开更多
By using activator to change the state of crude oil and to diminish the size of dispersed phase,mass transfer in distillation process is intensified and distillate yield is increased.In this work,the new activators R1...By using activator to change the state of crude oil and to diminish the size of dispersed phase,mass transfer in distillation process is intensified and distillate yield is increased.In this work,the new activators R1 and R2 were used as the additives respectively,and the intensifying effects to Daqing crude oil were examined at different concentrations and liquid phase temperatures by means of simple distillation and TBP distillation.The interaction mechanisms between the new activators and the crude oil or residues were analyzed,the intensifying effects by the new activators were also studied.Finally,the conceptual technique of “chemical intensification distillation”was put forward.展开更多
