Method for increasing deasphalted oil production
Patent
·
OSTI ID:6412198
A method for increasing the production of deasphalted oil is described. The method comprises passing a hydrocarbon feedstock into a first distillation zone wherein the feedstock is separated into a first distillate and a first residuum. First residuum is passed to a second distillation zone wherein the fraction is separated into a second distillate and a second residuum. Second distillate and residuum are passed to a deasphalting zone and contacted with a solvent to produce a deasphalted oil. This method may produce increased quantities of acceptable quality deasphalted oil where the deasphalting zone is rate-limiting.
