The primary separation operation for crude oil occurs when the crude stream flows through a vessel of sufficient capacity to allow gravitational separation of the gas, liquid hydrocarbon and water phases. This fluid mixture then flows into a horizontal separator vessel fabricated of clear PVC. Gas flow passes through a secondary vertical 2-phase separator. This process trainer blends air, water and refined oil to emulate a crude oil stream. The entire trainer is controlled from an optional distributed control system or dedicated control panel. The separator is equipped with industry-typical process measurement devices.
