Effective separation in a small footprint for constrained spaces

The process begins by providing pressurized water to a venturi-type eductor that creates a vacuum at the gas suction port, where the gas is introduced into the waterstream. The mixture is combined with the incoming produced water stream and then passes through a dispersing mechanism where small gas bubbles are formed. The bubbles interact with the oil and solids particles present. This stream passes through a baffle section within the separator vessel central riser at a reduced velocity, allowing the gas and oil and solids particles to flocculate prior to being released at the surface of the vessel.

The oil is periodically skimmed from the vessel into a skim trough by raising the operating level to a point just above the skim trough. As the liquid level rises, it spills over into the oil trough. When the skim cycle is complete, the level set point is reset, and the unit automatically returns to normal operation.

The intermittent skimming cycle reduces the oil skim rate to approximately 1% of the average daily flow.
