Abstract
A system for separating a liquid and a gas including a separation vessel (30) with an inlet (28) for a gas/liquid mixture. Outlets (40, 42) for the fluids are disposed at different heights in the vessel. The outlets are controlled by turn-up vortex amplifiers (fluidic valves TuVAs) that include a supply port (40, 42), a control port (36, 38) and an outlet port (48, 50). The control port is supplied from the vessel at an intermediate level between the outlets, so that a change of flow in the control port alters resistence to flow through the valve.
