What is an Amine Unit?

Amine units are used in the gas processing industry for Hydrogen Sulfide Removal. Hydrogen Sulfide is a common chemical found within natural gas that is produced from oil and natural gas wells. Hydrogen sulfide or H2S, is highly corrosive and lethal if breathed with high enough concentrations. H2S removal is also referred to "gas sweetening" or "acid gas removal" and typically occurs in the midstream oil and gas at gas processing plants.

Amine plants provide H2S removal as well as CO2 removal from natural gas and liquid hydrocarbons. The H2S removal process involves both absorption and chemical reactions and uses a group of chemicals called "amines."  There are five types of amines typically used in natural gas treating and include:

• Monoethanolamine (MEA)
• Diethanolamine (DEA)
• Methyldiethanolamine (MDEA)
• Diisopropylamine (DIPA)
• Diglycolamine (DGA)

The most commonly used amines in industrial plants are DEA, MDEA and MEA.

What is Desiccant Dehydration?



Desiccant Dehydration is a "natural gas treating" technology similar in the end result as other gas processing technologies including gas dehydration or glycol dehydration, with the exception that Desiccant Dehydration does not use amines.  Desiccant Dehydration uses "adsorption" technology to "dry" the natural gas.

Desiccant Dehydration using the adsorption typically consists of two (or more) adsorption towers. Each of these adsorption towers alternate between cycles wherein one tower is actively removing water/moisture from the gas stream, while the other adsorption tower is being "re-generated." Each of these adsorption towers are filled with a "desiccant" that can adsorb a limited amount of water and therefore require re-generation, typically by heat.

Standard desiccants include activated alumina or a granular silica gel material.

In the Desiccant Dehydration process, wet natural gas enters the adsorption towers, from the top and the wet natural gas flows down through the desiccant material, to the bottom. of the adsorption tower. As the wet natural gas passes around the desiccant material, water is separated from the natural gas which is "adsorbed" on the surface of these desiccant particles. By the time the natural gas reaches the bottom of the adsorption tower, over 98% of the water is adsorbed onto the desiccant material, leaving the dry gas to exit the bottom of the adsorption tower. After the desiccant in the active adsorption tower has adsorbed all the water/moisture it can, and reaches capacity, that active adsorption tower is shut down, and an adjacent adsorption tower then activates. During this time, the adsorption tower that has been shut down is "re-generated" and the water/moisture that was adsorbed by the desiccant is heated that vaporizes the water molecules, thereby "recharging" the desiccant and making it ready for use, when the adjacent adsorption tower has completed its cycle.
