摘要： 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.
