The main purpose of a gas sweetening unit is to reduce the CO2 and H2S levels to commercially and environmentally acceptable amounts. These gases, frequently found in natural gas streams, are highly toxic, extremely corrosive, and can significantly reduce the BTU value of the gas.

Other advantages of using gas sweetening units are:
1. Reduced manufacturing times, and,
2. Reduced hazardous risk to the environment

 Gas sweetening units are common process units as used in oil refineries, petrochemical plants, natural gas processing plants, etc.

Gas sweetening units, (also known as amine treating units), are a processing unit that removes contaminants from gas, making it environmentally suitable for transportation and commercial use. The process is referred to as sweetening and it processes gases so they no longer have the sour, foul odors of mercaptans and hydrogen sulphide.

The sweetening process entails mixing the sour gas with an amine solution, which absorbs the acidic gases later in the process as the mixture is heated and cooled until the purified and acidic gases are separated.

Failing to lower the salt and other contaminants from the crude oil can cause corrosion and fouling to the downstream equipment and also lower the economical value of the crude due to the high cost of production. After the oil has been washed and mixed, resulting in an emulsion of oil and water, demulsifying chemicals are added and electrostatic fields are used to break up the emulsion.



It is sometimes equipped with different meters to determine oil, water and gas rates, necessary to diagnose well problems, evaluate production performance of individual wells, and manage reserves properly. Separators work on the principle that the three components have different densities, which allows them to stratify when moving slowly, with gas on top, water on the bottom, and oil in the middle.

Glycol dehydration units are most predominantly used for removing large amounts of water, and adsorption is used for cryogenic systems to reach low moisture contents. Natural gas in transit to market should be dehydrated to a controlled water content to avoid hydrate formation as well as minimize corrosion problems.



The purpose of gas conditioning units is to pre-treat natural gas and other combustible gasses prior to injecting them into a more critical process or a gas turbine generator. The liquid contaminants are collected in a sump and automatically drained from the system for easy operations. All system components and piping are skid-mounted for transport and installation. Removal of all liquid droplets and solid contaminants from the gas, and, 2.
