Abstract:
1. A gas and liquid phase contactor comprising a vessel comprising an inner wall; a pressurised source of liquid; and a gas inlet communicating with a gas and liquid phase contacting space within the vessel, a distributor apparatus for distributing liquid in the vessel, comprising at least one housing rotatable about an axis of the housing; each rotatable housing having a distributor region comprising at least one liquid outlet or arrangement of liquid outlets arranged in a formation in and around the housing for directing liquid through the gas liquid contacting space towards the inner wall of the vessel, the distributor apparatus having a liquid inlet for introducing liquid into the housing from the pressurised source of liquid and providing pressurised liquid to the at least one liquid outlet or arrangement of liquid outlets, the pressurised liquid in the housing projecting from the housing as at least one liquid sheet rotating around a central axis of the housing towards the inner wall of the vessel; the liquid sheets having two sides and the gas inlet directing gas through the gas liquid contacting space into contact with each side of the at least one liquid sheets projected from the outlets in the housing, wherein the formation of the outlets in and around the housing is helical or spiral and creates a liquid sheet or sheets in a helical or spiral pattern extending towards the radial boundaries of the gas and liquid phase contacting space, and wherein the pitch of the outlets is in the range of 0.2 to 6 times the outer diameter of the housing.
