Abstract
A method for stabilizing whole crudes and condensate hydrocarbon mixtures. The method includes feeding a hydrocarbon mixture to a stabilizer column and separating the hydrocarbon mixture into an overhead offgas effluent and a stabilized hydrocarbon mixture; reboiling a stream from the stabilizer column with a heating medium, producing a reboiled stream; feeding the reboiled stream into the stabilizer column; heating a first side-stream from the stabilizer column with a stabilized hydrocarbon mixture from the stabilizer column, producing a heated first side-stream from the stabilizer column; and feeding the heated first side-stream into the stabilizer column.

A method for stabilizing whole crudes and condensate hydrocarbon mixtures, the method comprising:
- feeding a hydrocarbon mixture to a stabilizer column and separating the hydrocarbon mixture into an overhead offgas effluent and a stabilized hydrocarbon mixture;
- reboiling a stream from the stabilizer column with a heating medium, producing a reboiled stream;
- feeding the reboiled stream into the stabilizer column;
- heating a first side-stream from the stabilizer column with a stabilized hydrocarbon mixture from the stabilizer column, producing a heated first side-stream from the stabilizer column;
- and
- feeding the heated first side-stream into the stabilizer column.
A system for stabilizing whole crudes and condensate hydrocarbon mixtures, the system comprising:
- a stabilizer column for separating the hydrocarbon mixture into an overhead offgas effluent and a stabilized hydrocarbon mixture, a stabilizer column comprising:
- a feed inlet;
- a reboiler outlet;
- and
- a reboiler inlet;
- one or more heat exchangers;
- a reboiler for reboiling a stream from the stabilizer column with a heating medium, producing a reboiled stream from the stabilizer column, and feeding the reboiled stream into the stabilizer column;
- and
- a product pump fluidly connected to a bottom of the stabilizer column;
- wherein the one or more heat exchangers comprises:
- a first heat exchanger outlet receiving a first side-stream from the stabilizer column disposed at an elevation above the reboiler outlet and below the feed inlet;
- a first heat exchanger inlet receiving a heated first side-stream from the first heat exchanger disposed at an elevation below the first heat exchanger outlet of the stabilizer column;
- and
- a first heat exchanger for heating the first side-stream from the stabilizer column with the stabilized hydrocarbon mixture, producing the heated first side-stream from the stabilizer column, and feeding the heated first side-stream into the stabilizer column.
