a multi - phase separation apparatus shapes fluid flow in a flow shaping line preferably shaped to have a plurality of loops with consecutively decreasing diameters . shaping the two - phase flow drives the heavier , denser fluids to the outside wall of the flow shaping line and allows the lighter , less dense fluids such as gas to occupy the inner wall of the flow shaping line . with the gas positioned on the inner wall , an exit port on the inner wall permits a majority , if not all , of the gas , along with a minimal amount of liquid , to be diverted to a conventional gas - liquid separator at a flow rate much lower than the total flow rate within the flow shaping line . the remaining liquid flow in the flow shaping line is subsequently introduced into an adjustable phase splitter to separate different liquid components from one another .
