Abstract
A process for upgrading crude oil may include combining crude oil and feed water in a supercritical water unit to produce a first upgraded output, separating the first upgraded output in a first gas-water-oil separator to produce a first gas effluent, a first water effluent, and a first oil effluent, separating the first water effluent in a first water treatment unit to produce a rejected water stream and a recycle water stream, combining the first oil effluent and the rejected water stream in a nearcritical water unit to produce a second upgraded output, and recycling at least a portion of the recycle water stream for introduction into the supercritical water unit. A system for upgrading crude oil may include a supercritical water unit, a first gas-water-oil separator disposed downstream of the supercritical water unit, a first water treatment unit disposed downstream of the first gas-water-oil separator, and a nearcritical water unit.
