LEAN OIL ABSORPTION AND STABILIZATION

摘要

The invention provides a process and a system for processing hydrocarbon streams efficiently, especially natural gas streams that contain natural gas liquids including propanes, butanes, pentanes and higher hydrocarbons. A lean oil absorber is used to separate natural gas liquids, a side stripper with a side stripper reboiler is used to separate a propane/butane stream and a stabilizer reboiler is used to stabilize a natural gasoline product stream.

主权项

1. A process for purifying a hydrocarbon stream comprising:
(a) sending said hydrocarbon stream through a lean gas absorber; (b) sending a vapor stream out a top of said lean gas absorber; (c) sending a heavier hydrocarbon portion out a bottom of said lean gas absorber; and (d) sending said heavier hydrocarbon portion to a column to be separated into a light hydrocarbon portion comprising methane and ethane exiting a top of said column, a heavy hydrocarbon portion exiting a bottom of said column comprising pentanes and heavier hydrocarbons and a middle portion comprising butanes and propanes.
