A slug flow separator facilitates the separation of a mixture flow into component parts. The separator includes an upper-tier elongate conduit, a lower-tier elongate conduit and a plurality of spaced apart connectors. Each of the upper and lower-tier elongate conduits has an outlet and at least one of the upper and lower-tier elongate conduits has an inlet for receiving the mixture flow. The upper and lower-tier elongate conduits also each have a plurality of openings such that one connector of the plurality of connectors may interconnect one of the upper-tier elongate conduit openings with a one of the lower-tier elongate conduit openings. The connectors enable communication of at least one of a liquid component and the at least one of another liquid component and a gas component of the mixture flow therebetween.
