Systems and methods for crude oil separations including degassing, dewatering, desalting, and stabilization, one method including separating crude oil into a crude oil off-gas and a partially degassed crude oil output; compressing the crude oil off-gas; applying the compressed crude oil off-gas for indirect heating of the partially degassed crude oil output; further heating the partially degassed crude oil output indirectly with compressed low pressure gas; directly mixing with the partially degassed crude oil output a compressed atmospheric pressure gas; separating from the partially degassed crude oil output a low pressure gas for use in the step of further heating; and separating from the partially degassed crude oil output an atmospheric pressure gas for use in the step of directly mixing.

A method of upgrading oil using supercritical fluids generated by a fuel cell. The process uses supercritical carbon dioxide to control the specific gravity of the oil and supercritical water, the amount of which is controlled to achieve a desired oil/water ratio in processing oils to be upgraded. The process recovers the GHG emission stream from a fuel cell anode exhaust to produce supercritical fluids.

A method for determining the quality of crude oil exiting a gas-oil separation plant (GOSP) is disclosed. The GOSP comprises sensors that determine process parameters of the crude oil. The method involves determining, from the process parameters, WiO-parameters that depend on the concentration of water in the crude oil (WiO), determining virtual parameters of the crude oil, determining total parameters by adding the virtual parameters to the WiO-parameters. Further, a feedback loop involves changing one or more of the total parameters, determining the quality of the crude oil exiting the GOSP, wherein when the quality is improved, the change in the one or more total parameters is maintained, and when the quality is worsened, the change in the one or more total parameters is reversed. The feedback-loop is repeated as long as the quality of the crude oil exiting the GOSP increases.

A process is provided for removing organic chlorides from glyceride oil. The process includes the steps of (a) reacting a glyceride oil comprising organic chlorides with a liquid aqueous system at a temperature of at least 80° C. to form a treated glyceride oil and (b) separating the treated glyceride oil from the liquid aqueous system. The treated glyceride oil has a reduced concentration of organic chlorides compared to the glyceride oil reacted in step (a).

Embodiments of the disclosure include processes using microwave heating to promote the separation of components of crude oil. In some embodiments, microwave-heated water may be used to heat the interphase between the gas phase and the oil phase of a crude oil stream to promote the separation of sulfur (for example, H.sub.2S) and light end components of the crude oil stream. In some embodiments, microwave-heated water may be used to heat the interphase between the oil phase and the water phase of a crude oil stream to promote the separation of water, salt, or both of the crude oil stream. Systems having a microwave unit to provide microwave-heated water to crude oil stream are also provided.
