1. A process for stabilizing a hydrocarbon feedstock comprising:
delivering the hydrocarbon feedstock to a feedstock inlet of a High Pressure Separation (HPS) unit in a separation stage between the feedstock inlet and a stabilized oil outlet, wherein the separation stage between the feedstock inlet and the stabilized oil outlet consists of only two stages of separation, wherein a first stage of separation is the HPS unit and a second stage of separation is a Heated LP Separator unit;
pressurizing the hydrocarbon feedstock in the HPS unit to separate at least one of a gas product or a water product from the hydrocarbon feedstock to generate an un-stabilized oil portion of the hydrocarbon feedstock;
discharging the un-stabilized oil portion of the hydrocarbon feedstock from an oil outlet of the HPS unit;
delivering the un-stabilized oil portion of the hydrocarbon feedstock directly to the Heated Low Pressure (LP) Separator unit downstream from the oil outlet of the HPS unit, wherein the LP separator unit includes a single vessel having an un-stabilized oil inlet, the stabilized oil outlet downstream from the oil inlet, a gas product outlet and a water product outlet;
heating the un-stabilized oil portion of the hydrocarbon feedstock in the Heated LP Separator unit with a heating input between the un-stabilized oil inlet and the un-stabilized oil outlet to separate at least one of a second gas product or a second water product from the un-stabilized oil portion of the hydrocarbon feedstock to generate a stabilized oil portion of the hydrocarbon feedstock; and
discharging the stabilized portion of the hydrocarbon feedstock from the stabilized oil outlet of the Heated LP Separator unit.
