Three Phase Separators are designed for gas, oil, and water. It is a vessel that separates the well fluids into gas and two types of liquids: oil and water. A three-phase separator can be horizontal, vertical or spherical. Vertical separators are designed primarily for intermediate gas-oil ratios, while horizontal separators are suited for high gas-oil ratios and constant flow well streams. At Engineered Pressure Vessels we manufacture three phase separators to the highest quality standards dictated by the ASME Boiler and Pressure Vessel Code.
