NGL Recovery * Gas Processing * Midstream Oil and Gas
What is NGL Recovery?
the end of the gas
processing process and natural
gas treating process, wherein the "raw" natural gas
(methane or CH4) is readied for sale as "pipeline
quality gas," the recovery of the valuable natural
gas liquids (NGL) takes place. In many gas
plant - which
provides low-temperature distillation that recovers the natural
gas liquids. The residue gas from the
NGL recovery process, is the purified pipeline
quality gas that is sold via pipeline
and sent so end-users such as LDCs (local distribution companies - or natural
gas utility) for distribution via natural gas mains in their cities and markets.
Other NGL recovery methods include an NGL fractionation "train" which typically consists of three distillation towers in a series. The series occurs in the following order:
The overhead product from the deethanizer is ethane - after which the bottoms flow to the depropanizer. The overhead product from the depropanizer is propane and the bottoms then flow to the debutanizer. The overhead product from the debutanizer is a mixture of normal butane and iso-butane. The bottoms products are a C5+ mixture. Most cryogenic plants, however, do not include fractionation due to economic reasons. Therefore the NGL stream is then transported as a mixed product to separate, standalone fractionation plants that are located near refineries or chemical plants that need these NGLs feedstock.

“spending hundreds and hundreds and hundreds of billions of dollars every year for oil, much of it from the Middle East, is just about the single stupidest thing that modern society could possibly do. It’s very difficult to think of anything more idiotic than that.”
~ R. James Woolsey, Jr., former Director of the CIA
According to R. James Woolsey, for Director of the Central Intelligence Agency, “The basic insight is to realize that global warming, the geopolitics of oil, and warfare in the Persian Gulf are not separate problems — they are aspects of a single problem, the West’s dependence on oil.”
