Q&A - CRUDE DISTILLATION
CRUDE DISTILLATION
Terry:
When I increased
crude tower bottom stripping steam from 1,200 to 2,500 lbs/hr, I increased
diesel yield by 1,000 BSD at the expense of LVGO. Vacuum, in the vacuum tower,
improved from 25 to 18 mm Hg. Yet, vacuum resid yield failed to improve. Why
not?
Norm:
Reduction in
vaporization of diesel in flash zone of vacuum tower, off-set reduction in
pressure:
·
% vaporized prop.
