Abstract: A stream splitting device splits a two-phase inlet stream into two or more outlet streams having nearly identical vapor-to-liquid ratios. The inlet stream is directed into a separator vessel containing an impingement plate to decrease the velocity of the stream and direct it toward the inner walls of the vessel, where it impinges, separating the liquid from the vapor. Inside the vessel, each of two vertical suction channels with side wall apertures is in fluid communication with an outlet pipe. The lower ends of the suction channels are submerged in the liquid phase. Vapor flows though the apertures that are above the liquid surface in the vessel, thereby generating a pressure drop across the walls of the suction channels. Consequently, liquid is lifted up into the suction channels, where it is mixed with the vapor. The two-phase mixture then leaves the vessel and stream splitter through the outlet pipes.
