  • Subsea flow enhancer
    Patent number: 5490562
    Abstract: The present invention is for a subsea hydrocarbon recovery device comprising a means for separating a composite hydrocarbon stream into a gas and liquid stream and independent means for recovering each stream. The device is comprised of a separator, a gas recovery pipeline and a liquid recovery system. The separator separates a composite hydrocarbon stream from a well into vapor and liquid phases. The liquid hydrocarbon recovery system is comprised of a circulating loop into which the liquid hydrocarbon stream is introduced for recovery. The liquid steam flows through a pressure increasing device into a circulating loop which brings the recovered hydrocarbon to the surface. Physical parameters of the circulating liquid can be controlled to prevent or eliminate paraffin accumulations.

  • Method for separating immiscible liquid
    Patent number: 5298167
    Abstract: An apparatus and a method are disclosed for separating a first fluid from a second fluid wherein the first fluid is lighter than the second fluid and the first fluid is immiscible with the second fluid. A first portion of the first fluid is separated from a mixture containing the first and second fluids in a gravity separator. The remaining mixture flows to a hydrocyclone where a second portion of the first fluid is separated from the remaining mixture. The underflow from the hydrocyclone which includes most of the second fluid and the remaining portion of the first fluid flows to a second gravity separator without substantial pressure reduction to avoid shearing of the droplets of the first fluid. In the second gravity separator a third portion of the first fluid is removed.

  • Water treating using a series coalescing flume
    Patent number: 4983287
    Abstract: A method and apparatus for removing oil from the produced water that is associated with the production of hydrocarbons. The method consists of providing a plurality of serially connected individual compartments with each compartment connected to the next compartment by a flow path that induces the oil droplets to coalesce. The method may also include the use of parallel plate coalescers and gas flotation devices to aid in treating.
