Abstract
Official abstract text for this publication.
The invention provides a process and system for processing natural gas and separating natural gas liquids into natural gasoline and a Y-grade liquid that meets specifications for low methane and ethane content. The process and system includes a side stripper and reboiler to separate methane and ethane from heavier hydrocarbons and a reboiler system to stabilize the natural gasoline.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for processing a stream containing natural gas liquids comprising: (a) sending said stream to a column; (b) removing a vapor comprising methane and ethane from a top of said column; (c) removing a portion of said stream from a middle section of said column and sending said portion to a side stripper to separate said middle portion into a light hydrocarbon vapor portion and a natural gas liquid product; and (d) removing a second portion of said stream from a bottom section of said column and sending said second portion to a stabilizer reboiler to separate said second portion into a stabilized gasoline product and a lighter hydrocarbon vapor portion to be returned to said column. 2. The process of claim 1 wherein said second portion of said stream contacts a liquid backup weir before exiting said column and being sent to said stabilizer reboiler. 3. The process of claim 1 wherein said stabilized gasoline product is a natural gasoline. 4. The process of claim 1 wherein said natural gas liquid product is a Y-grade natural gas liquid.
