A method and apparatus for separating production fluids using a system designed to minimize the heating requirements through thermodynamic efficiency and reduce equipment costs.

A method of desulfurizing a liquid hydrocarbon having the steps of: adding a liquid hydrocarbon to a vessel, the hydrocarbon having a sulfur content; adding a catalyst and an oxidizer to create a mixture; oxidizing at least some of the sulfur content of the liquid hydrocarbon to form oxidized sulfur in the liquid hydrocarbon; separating the liquid hydrocarbon from the mixture; and removing at least some of the oxidized sulfur from the liquid hydrocarbon. Such methods can be carried out by batch or continuously. Systems for undertaking such methods are likewise disclosed.

Systems and methods for controlling desalting and dehydration of crude oil, one method including monitoring total dissolved solids (TDS) content at an outlet stream from a crude oil separation unit, the outlet stream comprising water; monitoring basic sediment and water (BS&W) content at an outlet stream from the crude oil separation unit, the outlet stream comprising processed crude oil; determining pounds per thousand barrels (PTB) salt content and volumetric water content of a dried, desalted crude oil product stream using the TDS content and BS&W content; and controlling a process input to the method from a comparison between the PTB salt content and volumetric water content of the dried, desalted crude oil product stream versus a maximum set value for PTB salt content and volumetric water content of the dried, desalted crude oil product stream.

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.

The present invention is directed to a dry tomb landfill for biological carbon sequestration, and more particularly to a dry tomb biolandfill having biomass enclosed by top and bottom seals containing at least one barrier to water transport, a covering layer that functions to protect the enclosed biomass from atmospheric disturbance, one or more accessible pipes or conduits connected to the enclosed biomass, and means to monitor biomass decomposition of the enclosed biomass

A system for conditioning live crude oil to produce stabilized oil that can be stored in a conventional oil storage tank and hydrocarbon gas includes a stabilizer tower and a heater treater. The stabilizer tower receives oil from separators at the wellhead production facility and outputs oil to the heater treater. The heater treater outputs gas back into the stabilizer tower and, optionally, recycles a portion of oil output back into the heater treater, which enhances oil output.
