Nowadays, the efficient separation of multiphase mixtures has a great importance in offshore installations where space is limited. In this case, the use of Compact Cyclonic Separators (CCS) has gained popularity because it is simple, compact, and economical to manufacture and operate. Its operation field is established on the basis of superficial velocities of liquid and gas within the separator, being limited by the occurrence of two phenomena: the Liquid Carry-Over (LCO) and the Gas Carry-Under (GCU) in the discharge pipes of gas and liquid respectively. Taking into account this two main phenomena, in the present experimental study was determined the operation field and performance of an Axial Vortex Separator (SVA) of 3’’ in diameter for a water-air mixture flow. SVA is composed by two vertical concentric tubes. The inner tube has a stator to generate a vortex centrifugal force which combined together with the buoyancy and gravity forces can separate the phases. SVA behavior was studied for different relative positions of the concentric tubes and two different angles from the stator blades. The experimental results were used to analyze the accuracy of mechanistic models available in literature for prediction of LCO and the flow patterns presented in the SVA. A good agreement was accomplished. Additionally, the operational envelope of SVA with 0% and 1% of LCO was determined. The SVA minimum separation efficiency in the experimental tests carried out was 99%.
