In this trainer air, water and oil are mixed to emulate a crude oil stream. This fluid mixture flows into a horizontal separator vessel fabricated of clear Plexiglas and equipped with industry-typical process measurement devices. Separator works on the principle that the three components have different densities, which allows them to stratify when moving slowly with gas on top, water on the bottom and oil in the middle. The separator vessel is equipped of diverter baffle, demister and control loop for air and oil flow rate, for the level of oil, water and a loop for controlling the gas pressure. The liquid separated products are recollected by gravity to feed tanks and gas (air) vented. The system is equipped with two PID controllers with electric and pneumatic system and it is integrated with computerized control system (SCADA). Note that the process uses safety fluid in operation (water, oil, air) and have emergence push button.
