MULTIPHASE SEPARATOR, AND METHOD OF SEPARATING A MULTlPHASE FLUID

Multiphase separator for separating a multiphase fluid produced by one or more oil wells, the multiphase separator comprising:

• a separating vessel, comprising an inlet chamber and an oil chamber for collecting oil at least partially separated by a barrier;
• an inlet for introducing the multiphase fluid into the separating vessel;
• wherein the oil chamber is positioned on the opposite side of the barrier to the inlet;
• a gas outlet configured to collect gas separated from the multiphase fluid;
• an oil outlet configured to collect oil, separated from the multiphase fluid, from the oil chamber;
• a water outlet configured to collect water separated from the multiphase fluid;
• a gas and water mixture injector configured to inject a mixture of pressurized gas and water in a lower portion of the separating vessel;
• a solids collection system for collecting solid material deposited at the bottom of the separating vessel;
• and
• a cleaning system configured to inject pressurized water in a downward angled direction towards the bottom of the separating vessel to direct a swept flow of water to the solids collection system.
