Boil by increasing temperature or reducing pressure?

    Which one is cheaper to do if I have a reactor at 45 bar, 80C and wish to distill a substance before it enters another reactor at 15 bar, 150C?

    Funny stuff you're dealing with ! What is it ? I don't get the complete picture, I think. Usually things flash when the pressure is reduced. You sure you mean a distillation step between two reaction steps ? And then the bottom product goes to the second reactor ?

    Reducing pressure alone will not cause continuous boiling: you still need heat.

    You will need to do a real analysis of the potential processes to determine which fits your needs better.
