Crude oil stabilization

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.

2. The process of claim 1 , wherein pressurizing the hydrocarbon feedstock in the HPS unit includes operating the HPS unit at a pressure ranging from 75 psig to 250 psig to the hydrocarbon feedstock.

3. The process of claim 1 , wherein heating the un-stabilized oil portion of the hydrocarbon feedstock in the Heated LP Separator unit includes heating the hydrocarbon feedstock to a temperature above 110° F.

4. The process of claim 1 , wherein heating the un-stabilized oil portion of the hydrocarbon feedstock in the Heated LP Separator unit includes heating the hydrocarbon feedstock to a temperature ranging from 110° F. to 160° F.

5. The process of claim 1 further comprising pressurizing the un-stabilized oil portion of the hydrocarbon feedstock in the Heated LP Separator unit by operating the Heated LP Separator at a pressure less than 20 psig.

6. The process of claim 1 , further comprising pressurizing the un-stabilized oil portion of the hydrocarbon feedstock in the Heated LP Separator unit by operating the Heated LP Separator unit at a pressure ranging from 3 psig to 10 psig.

7. The process of claim 1 , wherein the stabilized portion of the hydrocarbon feedstock discharged from the oil outlet of the Heated LP Separator unit has a Reid Vapor Pressure (RVP) of less than 10 psi.

8. The process of claim 1 , wherein discharging the stabilized portion of the hydrocarbon feedstock from the oil outlet of the Heated LP Separator unit includes discharging the stabilized portion of the hydrocarbon feedstock to a Lease Automatic Custody Transfer (LACT) unit downstream from and in fluid communication with the oil outlet of the Heated LP Separator unit.

9. The process of claim 1 , wherein the hydrocarbon feedstock is at least one of shale oil or tight oil.

10. The process of claim 1 , further comprising discharging the gas product through a gas product outlet of the HPS unit.

11. The process of claim 1 , further comprising discharging the second gas product from a gas product outlet of the Heated LP Separator unit.

12. The process of claim 11 , further comprising recovering the second gas product with a vapor recovery unit downstream from and in fluid communication with the gas product outlet of the Heated LP Separator unit.

13. The process of claim 11 , further comprising recovering the second gas product with a vapor recovery unit downstream from and in fluid communication with the gas product outlet of the Heated LP Separator unit.
