Process for increasing Bright Stock raffinate oil production |
摘要 |
A process for increasing the production of Bright Stock oil in a lube oil process scheme. Aromatic extract oil, after being separated from the extraction solvent, is recycled back to the deasphalter unit and combined with a vacuum residuum in 10-20 LV %, based on the total deasphalter feed, prior to deasphalting. After deasphalting and aromatics extraction the absolute yield of raffinate is increased.
