Document Type and Number:
WIPO Patent Application WO/2012/005948
Kind Code:
A3
Abstract:
A process for upgrading an oil stream by mixing the oil stream with a water stream and subjecting it to conditions that are at or above the supercritical temperature and pressure of water. The process further includes cooling and a subsequent alkaline extraction step. The resulting thiols and hydrogen sulfide gas can be isolated from the product stream, resulting in an upgraded oil stream that is a higher value oil having low sulfur, low nitrogen, and low metallic impurities as compared to the oil stream.
