  • Patent number: 7850843
    Abstract: A more energy-efficient method of processing crude oil is achieved by viscoelastic shearing in order to increase the vapor pressure of the crude oil. This change in vapor pressure allows a more efficient separation of volatile components from non-volatile components in the crude oil. By optimizing the energy expenditure for shearing and the energy expenditure for separating the volatile components from the non-volatile components of the crude oil, while simultaneously removing the volatile components by distillation, one can reduce the overall energy input for the separation. Alternatively, it is possible to affect the distillation at a reduced temperature.

Membrane separation and pressure swing adsorption is used to separate components of syngas and feed them to refineries, GTL units, and power/steam generation units. Hydrogen-rich refinery purge is used to raise the H2/CO ratio of syngas. A hydrogen-enriched syngas is produced with an H2/CO ratio favorable for the production on synthetic hydrocarbons (greater than about 1.5 to about 2.0 or higher). Pure hydrogen is also produced in a PSA unit, to further raise the H2/CO ratio of the syngas and provide hydrogen feed for refinery hydrotreators and synthetic hydrocarbon units (such as methanol units).

  • Patent number: 6540023
    Abstract: A process for producing a diesel fuel stock from bitumen uses steam, naphtha and a hydroisomerized diesel fraction produced by a gas conversion process, to respectively (i) stimulate the bitumen production, (ii) dilute it for pipeline transport to an upgrading facility, and (iii) increase the cetane number of a hydrotreated diesel fuel fraction produced by upgrading the bitumen by blending it with the hydroisomerized gas conversion diesel fraction, to form the diesel stock. This diesel stock has a higher cetane number than that produced from the bitumen alone, and is used for blending and forming diesel fuel.

  • Publication number: 20020189668
    Abstract: A method and apparatus for facilitating the pumping of crude oil through a pipe is disclosed. The facilitation includes receiving the crude oil through an input end of the pipe, processing the crude oil within the pipe to lower viscosity by at least partially cracking the crude oil into lower fractions and providing processed crude oil at the output end of the pipe in a reduced viscosity form. The step of processing the crude oil includes establishing an electrical discharge in proximity to the input end and passing the crude oil sufficiently close to the electrical discharge such that at least a portion is subjected thereto.

  • Patent number: 6337011
    Abstract: A method for lowering the cloud/pour point of a waxy crude oil in locations where size and/or weight of the facility may need to be limited (i.e. arctic zones and offshore). The major components of the system comprise a fractionation/quench tower and a reaction furnace. The furnace has sufficient heat input to initiate thermal cracking of wax and the fractionation tower is operated at a temperature sufficient to flash off light hydrocarbons but also low enough to quench thermal cracking reaction. The feed to the furnace comprises a portion of the bottoms stream from the tower and the furnace output is fed back into the tower bottom to be quenched.

  • Patent number: 5824214
    Abstract: Heavy crude oil containing at least 1% by weight water is hydrotreated and upgraded while being produced downhole in a production well. During production the heavy crude oil containing water is subjected to sonic energy at a low frequency of 400 Hz to 10 kHz downhole in the presence of a metal hydrogenation catalyst that causes the water in the crude oil to react and form hydrogen which then hydrotreats and upgrades the heavy crude oil during production. In another embodiment, if the heavy crude oil does not contain water, the hydrogen may be formed in-situ by contacting the heavy crude oil downhole with a chemical compound comprising ammonia, hydrazine and formic acid that in the presence of a metal hydrogenation catalyst and sonic energy causes the chemical compound to react and form hydrogen which then hydrotreats the heavy crude oil during production. Suitable catalysts include nickel on zinc dust, platinum on carbon and palladium on carbon, preferably nickel on zinc dust.
