  • Patent number: 9902910
    Abstract: A method and apparatus a crude oil treating apparatus includes a treating section and a flashing section connected together by a pipe and a flashing valve. The method includes the steps of passing wet crude oil into the treating section; separating water from the wet crude oil in the treating section; obtaining partially dry crude oil; passing the partially dry crude oil via the pipe and the flashing valve to the flashing section of the apparatus; heating the partially dry crude oil upstream of the flashing section and downstream of the flashing valve by heat exchange with the water separated from the crude oil in the treating section; and obtaining dry crude oil from the flashing section.

  • Patent number: 9155989
    Abstract: A method and system for purification of a pressurized gas stream, wherein the method includes in a first absorption step bringing the pressurized gas stream in direct contact with a first absorption solution absorbing at least part of the acidic gases, in the gas stream obtaining a gas liquid mixture; and separating the gas liquid mixture in a partly purified pressurized gas stream and a first rich absorption solution. In a second downstream absorption step bringing the partly purified pressurized gas in contact with a second absorption solution through a membrane contactor, obtaining a second rich absorption solution and a purified pressurized gas stream. The first absorption solution is a partially lean absorption solution.

  • Patent number: 8795521
    Abstract: A nut shell filter allows the shell filter media to be scrubbed without being removed from the filter vessel. In order to protect the vessel from pressure surges which can occur during the scrubbing cycle, pressure applied during the beginning of the scrubbing cycle is contained within a scrubber tube such that the filter vessel is not subjected to pressure surges which occur at the beginning of the scrubbing cycle. The scrubber tube and scrubber filter tube may either be disposed within the filter vessel or outside of the filter vessel.

  • Patent number: 8702952
    Abstract: An electrically energized compact coalescer (50) comprising an elongated, closed shell (53) having a fluid inlet (52) and a fluid outlet (59); at least one electrode (55) mounted in an internal chamber formed in the closed shell and forming at least one narrow gap (58) between the electrode means and a wall in the closed shell. An external power supply (64) is electrically connected to the electrode and the energized electrode (55) is fully encapsulated with insulation to enable an intense electrostatic field to be applied to an electrically conductive emulsion whereby the flow of emulsion through said at least one narrow gap (58) will be non-laminar. One or more helical vanes (57) are disposed in the narrow gap at an angle with respect to the electrode longitudinal axis and extending for at least a portion of the length (L) of the electrode, whereby the fluid flowing through said narrow gap will follow a spiraling pattern at least partially around the electrode (55).
