These separators will use cyclones, vane packs, mesh pad mist eliminators, and other types of plate packs.
Three-phase separators change with the gas-oil ratio (GOR), relative water to oil ratios, turndown percentage and pressure changes. Internal velocities including gas and liquid settling are critical. Three-phase separators, two-phase separators, and double barrel horizontal separators all require level controls. Since the separators have interned chambers with weirs, down comers, and filter coalescers, there is a need for external piping. The separators are pre-piped with the necessary manual and control valves. The option if local PLC control or central control is available.
Sep-Pro, being an ASME code shop, builds all the vessels and piping systems. Since the separators usually have heavy wall thicknesses, heat-treating is usually required. For corrosive environments the vessels can also be internally coated.
