Method and system for y-grade upgrader

A system for stabilizing and separating Y-grade natural gas liquids (NGL), comprising:

• an input stream comprising unfractionated NGL;
• a stabilization system comprising:
• a stabilization column comprising a packing material packed within the stabilization column, wherein an NGL solvent stream is separated from the input stream as the input stream descends through the packing material to produce a stabilized crude oil stream at a base of the stabilization column;
• a recycle loop comprising a heater, wherein the recycle loop measures a reid vapor pressure (RVP) of the stabilized crude oil stream and recycles the stabilized crude oil stream into the stabilization column if the reid vapor pressure (RVP) of the stabilized crude oil stream falls outside a predetermined range, wherein the stabilized crude oil stream is heated by the heater prior to being recycled into the stabilization column;
• and
• a reflux loop operable to recycle a portion of the NGL solvent stream into the stabilization column to offset deviations in mass flowrate of the stabilization system.
