A SYSTEM AND A METHOD FOR CONTROL OF OIL AND GAS FLOW IN CONDUITS
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). A crossflow manifold (10) is arranged between said first and second pipelines (20,22) and the sand separator equipment (30), where the crossflow manifold (10) is arranged to steer oil and gas from the first pipeline (20) to an inlet line (32) of the sand separator equipment (30), and to steer oil and gas from an outlet line (34) of the sand separator equipment (30) and to the second pipeline (22), and also that the crossflow manifold (10) is arranged to steer oil and gas from the second pipeline (22) to the inlet line (32) of the sand separator equipment (30), and to steer oil and gas from the outlet line (34) of the sand separator equipment (30) and to the first pipeline (20).
B01D 45/08 - Separating dispersed particles from gases or vapours by gravity, inertia, or centrifugal forces by utilising inertia by impingement against baffle separators
B01D 45/16 - Separating dispersed particles from gases or vapours by gravity, inertia, or centrifugal forces by centrifugal forces generated by the winding course of the gas stream
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).
