  • Patent number: 4566883
    Abstract: An apparatus for separating gas/liquid mixtures comprising an outer vessel having an inlet and separate gas and liquid outlets. A plurality of gas/liquid separating units are mounted in a horizontal tubesheet disposed in the vessel. Each separating unit has a vertical tubular member that defines an inner and outer space with the lower end of the tubular member communicating with the inlet. A swirl vane is mounted in each of the tubular members for imparting a swirl to the gas/liquid mixture to separate the gas and liquid. A primary gas outlet tube extends into each of the tubular members for removing the gas while the liquid is removed through discharge openings in the tubular members. Secondary gas outlets are positioned outside the tubular members while a demister mat is provided for removing any remaining liquid coming from the primary gas outlet tubes.
