Abstract
A hydrogen donor solvent selected from the group consisting of a full range crude oil and an atmospheric topped crude oil is used in a hydrovisbreaking process. The heavy fraction being processed is heated in the presence of hydrogen and the solvent under suitable hydrovisbreaking conditions. As a result, the amount of heavies in the feed to the hydrovisbreaking process is substantially reduced.
Claims11
A method for processing crude oil comprising steps of:
- providing a full range crude oil as a feed to an atmospheric fractionator;
- withdrawing an atmospheric topped crude oil from a lower portion of said atmospheric fractionator and providing at least a portion of said atmospheric topped crude oil as a feed to a vacuum fractionator;
- withdrawing a vacuum topped crude oil from a lower portion of said vacuum fractionator and providing at least a portion of said vacuum topped crude oil as a feed to a hydrovisbreaker;
- supplying hydrogen to said hydrovisbreaker;
- supplying a hydrogen donor solvent comprising the full range crude oil supplied to said atmospheric fractionator to said hydrovisbreaker, wherein at least a portion of the heavies in the portion of said vacuum topped crude oil provided to said hydrovisbreaker are cracked in said hydrovisbreaker;
- and
- withdrawing the reaction effluent from said hydrovisbreaker.
