Abstract: A riser-based slug control system and a method of controlling slugging in a fluid flowing through a riser are provided. The system includes a gas-liquid separation separator that has a housing defining an internal volume. An inclined inlet is connected to the housing and configured to receive a flow of multiphase fluid and direct the flow of fluid into the housing so that the fluid flows spirally in the volume and separates, with gas from the fluid collecting in an upper portion of the volume and liquid from the fluid collecting in a lower portion of the volume. A tubular passage, which extends at least partially through the internal volume of the housing, defines a plurality of orifices. The tubular passage is configured to receive liquid from the lower portion of the volume and gas from upper portion of the volume, and deliver the mixture of the combined liquid and gas through an outlet.

Abstract: A method and apparatus for inline, controlled water separation from a multiphase hydrocarbon production stream. The method includes the steps of directing the multiphase hydrocarbon production stream to a gas/liquid separator in order to separate into a gas stream and a liquid stream. The level of liquid in the gas/liquid separator is monitored and controlled. The liquid stream removed from the gas/liquid separator is directed to an enlarged pipe section in order to separate into an oil portion and a water portion. The level of the oil portion in the enlarged pipe section is monitored and controlled. The water portion from the enlarged pipe section is directed to a liquid-liquid cyclone centrifugal separator in order to separate into a water stream and a hydrocarbon concentrated stream. The water stream from the liquid cyclone centrifugal separator is directed to at least one de-oiling hydrocyclone separator.
