Process for producing Hydrocarbon fluids combining in situ heating, a power plant and a gas plant

An in situ method of producing hydrocarbon fluids from an organic-rich rock formation is provided. The method may include heating an organic-rich rock formation, for example an oil shale formation, in situ to pyrolyze formation hydrocarbons, for example kerogen, to form a production fluid containing hydrocarbon fluids. The method may include separating the production fluid into at least a gas stream and a liquid stream, where the gas stream is a low BTU gas stream. The low BTU gas stream is then fed to a gas turbine where it is combusted and is used to generate electricity.

Production of high-cetane diesel fuel from low-quality biomass-derived feedstocks

A method is taught for producing diesel fuels of high cetane value from a triglyceride feedstock, comprising pretreating the triglyceride feedstock by thermal cracking to partially convert the triglycerides and produce a middle distillates stream, and catalytically hydrotreating the middle distillate fraction to produce high cetane value diesel fuels. A biomass-derived diesel fuel is also taught having sulphur content below 10 ppm, a cetane-value of at least 70, a cloud point below 0° C. and a pour point of less than −4° C. A blended diesel fuel is also taught comprising 5 to 20 vol. % of the biomass-derived diesel fuel of the present invention and 80 to 95 vol. % of a petroleum diesel, based on total volume of the blended diesel fuel.

System for improving crude oil

Crude oil can be refined through a filtration media. Cavitation bubbles having localized areas of very high temperatures and pressures may be created thereby causing several physical and chemical phenomena, including thermal cracking of carbon-carbon bonds as the crude moves through the flux cartridge membrane. Heavy hydrocarbons are residues are thereby cracked into smaller lowering boiling molecules having a higher API gravity. Once the relatively smaller hydrocarbons pass through the flux cartridge membrane into the flux cartridge, the effluent can be routed to a second separator annulus. It should also be pointed out that lighter hydrocarbons formed can volatilize and special provisions may be needed to efficiently capture these gases.

Membrane separation for sulfur reduction

A membrane process for the removal of sulfur species from a naphtha feed, in particular, a FCC light cat naphtha, without a substantial loss of olefin yield is disclosed. The process involves contacting a naphtha feed stream with a membrane having sufficient flux and selectivity to separate a sulfur deficient retentate fraction from a sulfur enriched permeate fraction, preferably, under pervaporation conditions. Sulfur deficient retentate fractions are useful directly into the gasoline pool. Sulfur-enriched permeate fractions are rich in sulfur containing aromatic and nonaromatic hydrocarbons and are further treated with conventional sulfur removal technologies, e.g. hydrotreating, to reduce sulfur content. The process of the invention provides high quality naphtha products having a reduced sulfur content and a high content of olefin compounds.
