Abstract: A system and a method are described for control of flow of oil and gas in pipelines on an installation in connection with testing of the oil and gas from a well, comprising: at least, a first test manifold (12,16) to which a number of wells are connected, a first pipeline (20) for flow of oil and gas from said first test manifold to sand separator equipment (30), at least, a second test manifold (14;18) to which a number of wells are connected and a second pipeline (22) for flow of the oil and gas from said second test manifold to the sand separator equipment (30).

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 as 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).

Abstract: A particle collector for a dynamic cyclone placed on the ocean bottom for separation of particles in a fluid is described, where the dynamic cyclone comprises a tank (2) which is equipped with an upper inlet opening (25) and an upper and lower outlet opening (26, 32) for outflow of fluid and particles, respectively. Furthermore, the tank comprises a shaft (5) which is equipped with a number of vanes or blades (6) and which is arranged to be driven by an adjoining motor (1), where a centrally placed piece of pipe (4) with a number of slits is arranged around the shaft (5).
