A resid hydrotreating process hydrotreats a resid bottoms fraction from the reduction of crude oil. The hydrotreated bottoms fraction is then subjected to deep vacuum reduction and in some cases deasphalted by solvent extraction to produce an oil suitable for use as a catalytic cracking feedstock and a resins fraction suitable for solvating resid in a hydrotreating process.

Resid hydrotreating using solvent extraction and deep vacuum reduction

A process for improving the performance of heavy oil refining units in a resid hydrotreating unit equipped for resid hydrotreating. The partially refined resid stream issuing from a train of ebullated bed reactor is first separated into high, medium, and low temperature components. The high temperature component is sent through a flash drum and then fractionated by solvent deasphalting in order to provide oil, resin, and asphaltene fractions. Thus, the asphaltene is eliminated before it can foul downstream equipment. This treatment of the heavy oil product has several benefits as compared to treating the vacuum tower bottoms. Among other things, one of these benefits is to debottleneck the resid hydrotreating unit, especially at the atmospheric tower.

A refining process uses a two or four stage solvent separator coupled to receive an incoming feedstream of low sulfur resid and a solvent. In the preferred two stage separator, the mixture at the top of the first separator stage is fed to the second stage separator via a heat exchanger. The mixture at the bottom of the first stage separator includes resins and asphaltenes which are fed to a hydrotreater and then, in turn, to a fractionator. The output from the bottom of this fractionator can be fed back to the resid feedstream of the first stage separator for recycled separation. The material at the top of the second stage separator is fed back through the heat exchanger where it helps heat the mixture fed from the top of the first to the second stage separator, this feedback recovers the solvent for reuse in the first stage. The material settling to the bottom of the second stage separator is fed into a catalytic cracker or processed elsewhere.

Means for and methods of deasphalting low sulfur and hydrotreated resids

The inventive solvent extraction process uses hydrotreated (HTR) and low sulfur (LSR) resids feedstreams in a single deasphalter unit and in a way that optimizes the disposition of the oils, resins, and asphaltene fractions of each resid for downstream processing. After the refractory asphaltenes are separated from the HTR feedstream, the LSR resid is introduced into the deasphalter so that its resin and asphaltene fractions are combined with the HTR resins. The oils fractions from the two resids are combined and then used as a feedstock for catalytic cracking.

The invention reduces cracking catalyst fines in decanted oil by mixing the decanted oil (DCO) containing cracking catalyst fines with a resid oil and then treating the DCO-resid mixture with a non-aromatic hydrocarbon solvent in an extraction unit or in a multi-stage deasphalting unit.
