“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.”

What is Domestic Oil and Gas
Domestic oil and gas is simply oil and natural gas produced here in the U.S.A., by Americans, and NOT imported from foreign countries.

What
is an
Amine Plant?
Amine plants are used for "gas
sweetening" in the midstream oil and gas sector known as "gas
processing." Amine plants
provide H2S removal as well as CO2
removal from natural gas and liquid hydrocarbons. The process involves both
absorption and chemical reactions.
We
provide amine plant sales and natural gas processing and engineering services.
What is Amine?
Amine, is the shortened form of " Mono Ethanol Amine" or MEA. MEA removes H2S or acid gases through a chemical reaction with hydrogen sulfide or carbon dioxide which forms a salt compound (see Gas Sweetening diagram below).
When the MEA
has absorbed the H2S ( and carbon dioxide) it is referred to as "
rich" MEA.
When the acid gases have been removed from the mono ethanol amine it's called
lean MEA.
What
is a "cryogenic plant"?
A cryogenic
plant is another term for a "gas
processing plant."
Gas
processing plants produce
natural
gas liquids products, including ethane, at very low or "cryogenic"
operating temperatures.
What are
Gas
Compressors?
Gas compressors are mechanical device that increase the pressure of a gas by reducing its volume. Gas compressors are responsible for moving the natural gas from the oil or natural gas production well to homes and businesses via natural gas pipelines and gas compression stations.
Gas compression also increases the temperature of the gas during compression.
What
is
Gas Gathering?
Gas Gathering systems are the physical facilities that accumulate and transport natural gas from a well to an acceptance point of a transportation pipeline are called a gas gathering system.
What is
Gas Processing?
Natural Gas Processing plants separate the various hydrocarbons and natural gas liquids from the pure natural gas (methane or CH4) to produce what is known as 'pipeline quality' natural gas. Natural gas pipeline companies have requirements on natural gas they buy from producers which is why the natural gas processing plants are located where they are, and why they separate the ethane, propane, butane, and pentanes from the methane. Natural gas liquids or NGLs include ethane, propane, butane, iso-butane, and natural gasoline.
What is Gas Sweetening?
Sulfur exists in natural gas and is known as hydrogen sulfide (H2S). Natural gas is usually considered "sour" if hydrogen sulfides content exceeds 5.7 milligrams of H2S per cubic meter of natural gas. The process hydrogen sulfide removal from sour gas is commonly referred to as "gas sweetening."

Diagram of the Gas Sweetening Process
The
primary process for sweetening sour natural gas is quite similar to the
processes of glycol dehydration and NGL absorption. In this case, however, amine
solutions are used to remove the hydrogen sulfide. This process is known simply
as the 'amine process', or alternatively as the Girdler process, and is used in
95 percent of U.S. gas sweetening operations. The sour gas is run through a
tower, which contains the amine solution. This solution has an affinity for
sulfur, and absorbs it much like glycol absorbing water. There are two principle
amine solutions used, monoethanolamine (MEA) and diethanolamine (DEA). Either of
these compounds, in liquid form, will absorb sulfur compounds from natural gas
as it passes through. The effluent gas is virtually free of sulfur compounds,
and thus loses its sour gas status. Like the process for NGL extraction and
glycol dehydration, the amine solution used can be regenerated (that is, the
absorbed sulfur is removed), allowing it to be reused to treat more sour gas.
Although most sour gas sweetening involves the amine absorption process, it is
also possible to use solid desiccants like iron sponges to remove the sulfide
and carbon dioxide.
Sulfur can be sold and used if reduced to its elemental form. Elemental sulfur
is a bright yellow powder like material, and can often be seen in large piles
near gas treatment plants, as is shown. In order to recover elemental sulfur
from the gas processing plant, the sulfur containing discharge from a gas
sweetening process must be further treated. The process used to recover sulfur
is known as the Claus process, and involves using thermal and catalytic
reactions to extract the elemental sulfur from the hydrogen sulfide solution.

What is Glycol Dehydration?
Glycol dehydration is used in the production and processing of natural gas by using a liquid desiccant that removes water from natural gas and natural gas liquids (NGL).
Various types of glycols are used in this process including;
triethylene glycol (TEG)
diethylene glycol (DEG)
ethylene glycol (MEG)
tetraethylene glycol (TREG).
TEG is the most commonly used glycol in the natural gas industry.
What is
H2S
Removal?
H2S,
or Hydrogen Sulfide, is a hazardous and corrosive element found in oil and
natural gas which needs to be removed from the hydrocarbon before the oil or
natural gas can be sold. The
hydrogen
sulfides
are usually removed in a mid-stream gas processing facility by
either iron sponges or
amine plants.
What
is a Heater Treater?
A "Heater
Treater" is used in the oil and gas production process and is used to
removes water and gas from the produced oil - and to improve its quality for
sale into a crude oil pipeline or for other transport. A heater
treater typically combines the following components inside the heater
treater: a heater, free-water knockout, and oil and gas separator.
What is
Natural
Gas Treating?
As natural gas is produced from either a natural gas well, or from an oilwell which contains "associated gas," the natural gas must be treated or processed before it can be used at a home or business as a fuel.
Natural gas treating or processing, takes place at gas processing plants to remove the impurities and other hydrocarbons other than the methane itself, or CH4.
The by-products and impurities of natural gas that must be treated or processed include; ethane, propane, butane, isobutane, pentane, isopentane and higher molecular weight hydrocarbons, as well as H2S or elemental sulfur, carbon dioxide (CO2), water vapor and sometimes helium and nitrogen.
What is "NGL Fractionation"?
Natural gas liquids (NGL) fractionation plants separate the mixed natural gas liquids stream into separated products. These natural gas liquids that are separated by heat at NGL Fractionation plants include; ethane, propane, normal butane, isobutane and natural gasoline.
