Abstract: An oil conditioning unit includes a pump for receiving unstabilized crude oil at a first pressure and pumping the unstabilized crude oil at a second pressure higher than the first pressure, a first pre-heater downstream of the pump for heating the unstabilized crude oil to a first temperature, and a degassing vessel downstream of the first pre-heater. The degassing vessel is configured to separate light hydrocarbon gases from the unstabilized crude oil at the first temperature to produce stabilized crude oil having a Reid Vapor Pressure less than or equal to 13.7 psia. In some examples, the degassing vessel is configured to produce stabilized crude oil having a Reid Vapor Pressure well below 13.7 psia.
