Dynamic particle separator

Abstract

A dynamic particle separator is described for cyclone separation of sand from a gas stream in connection with petroleum related production of oil and gas where the separator comprises a housing (14) containing a cyclone tank (4) that is equipped with an upper inlet opening (1) for the gas stream and an upper and a lower outlet opening (2 12) for export of gas and particles respectively from the tank (4). The cyclone tank (4) is formed at least in an internal area around the inlet opening (1) with an upper and downwardly directed conical shape (4a) that increases in diameter and where the upper conical shape (4a) thereafter has a transition into an inverse lower conical shape (4b) that converges towards the lower outlet opening (12)
