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
("sour" natural gas contains H2S or hydrogen sulfides) 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. One sulfur recovery process is
called the "Claus" process, and involves the use of thermal and catalytic
reactions to extract the elemental sulfur from the hydrogen sulfide solution.

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 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 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 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.
We provide gas gathering, gas compressors, and other E&P services.
We are presently acquiring "midstream" energy plants and operations such as natural gas and natural gas liquids - along with the plant assets that treat natural gas - are found between exploration and production of oil and natural gas and the delivery to commercial, residential and industrial customers. Midstream energy assets include over 1 million miles of natural gas pipelines and 500 natural gas processing plants.
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.
