Multistage separator vessel for capturing LPGs

摘要

A method of recovering liquid petroleum gases (LPGs) from a wellbore includes: performing a well treatment operation by injecting the LPGs into the wellbore to increase the wellbore pressure; flowing a fluid stream from the wellhead into a separation vessel, the fluid stream comprising the LPGs; reducing the pressure of the fluid stream from the wellbore pressure to a separation vessel pressure, the fluid stream in the separation vessel comprising the LPGs in liquid form and in vapour form; separating the vapour form from the liquid form; transferring the liquid form of the LPGs to a pressure vessel; and passing the vapour form through a condenser to condense the vapour form, and depositing the condensed vapour form into the pressure vessel.

1. A method of recovering liquid petroleum gases from a wellbore, the wellbore having a wellbore pressure, the method comprising the steps of:
performing a well treatment operation by injecting the liquid petroleum gases into the wellbore to increase the wellbore pressure; transferring a fluid stream from the wellhead into a separation vessel, such that the fluid stream entering into the separation vessel comprising primarily liquid petroleum gases in a liquid state; reducing the pressure of the fluid stream from the wellbore pressure to a separation vessel pressure, the fluid stream in the separation vessel comprising the liquid petroleum gases in liquid form and in vapour form; separating the liquid petroleum gases in vapour form from the liquid petroleum gases in liquid form; transferring the liquid petroleum gases in liquid form to a pressure vessel; passing the liquid petroleum gases in vapour form through a condenser to condense the liquid petroleum gases in vapour form into liquid form; and depositing the condensed liquid petroleum gases in vapour form into the pressure vessel.
