Abstract
Official abstract text for this publication.
Contemplated plants for recovery of NGL from natural gas employ alternate reflux streams in a first column and a residue gas bypass stream, wherein expansion of various process streams provides substantially all of the refrigeration duty in the plant. Contemplated plants not only have flexible recovery of ethane between 2% and 90% while recovering at least 99% of propane, but also reduce and more typically eliminate the need for external refrigeration.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of recovering natural gas liquids from natural gas, the method comprising: feeding a vapor portion of a cooled feed gas in a first column to thereby form a first column bottom product and a first column overhead product, and configuring the first column to allow feeding of alternate first and second reflux streams to the first column such that the first column receives the first reflux stream during ethane recovery, and such that the first column re…
