Modelling of natural gas sweetening and dehydration processes.

What Is Gas Sweetening? Gas sweetening is the process of removing Hydrogen Sulfides, Carbon Dioxide, and Mercaptans from natural gas to make it suitable for transport and sale. Sour gas must be sweetened because H 2 S and CO 2 have a corrosive effect on gas pipelines and are also toxic to humans.

A Technical Report on Gas Sweetening by Amines.

Amine gas treating, also known as amine scrubbing, gas sweetening and acid gas removal, refers to a group of processes that use aqueous solutions of various alkylamines (commonly referred to simply as amines) to remove hydrogen sulfide (H 2 S) and carbon dioxide (CO 2) from gases. It is a common unit process used in refineries, and is also used in petrochemical plants, natural gas processing.Description of a natural gas processing plant: an overview 3. Sweetening of sour natural gas 3.1. Overview and Methods Used 3.2.. When processing sour natural gas, the sweetening process almost always precedes dehydration and other gas plant processes carried out for the separation of NGL.Other articles where Sweetening is discussed: natural gas: Sweetening: Sour gas is sweetened, or purified of its sulfur compounds, by treatment with ethanolamine, a liquid absorbent that acts much like the glycol solution in dehydration. After bubbling through the liquid, the gas emerges almost entirely stripped of sulfur. The ethanolamine is processed.


Sour gas or acid gas is a natural gas that contains hydrogen sulfide (H 2 S). The removal of H 2 S by using various aqueous solutions of akylamines, commonly referred to as amines, is known as gas sweetening. This process of gas sweetening is sometimes called amine treating or amine scrubbing.Gas Sweetening. Gas sweetening is a process that has to be executed to remove hydrogen sulphide (H2S) from gasses. Gas sweetening is sometimes referred to as amine treating. Amine treating can be used in refineries, petrochemical plants, natural gas processing plants and other industries.

Gas Sweetening Process Description Essay

Our expertise in sweetening processes includes multi-component absorption of inorganic and organic sulphur species. Gas sweetening is the process for the removal of mainly acid gases (H 2 S and CO 2) and, in addition, the simultaneous removal of sulphur organic species (RSH, COS, CS 2) from process gas. It is an essential step of sour gas processing for natural gas treatment, NGL recovery.

Gas Sweetening-Part 1: Comparison of Amines.

Gas Sweetening Process Description Essay

Opero Energy’s Amine Units utilize both generic amine solutions and proprietary-formulated solvents to treat either gas or NGL streams to required levels. The process involves contacting lean amine solution with sour gas to chemically absorb CO2 and H2S, creating a rich amine solution.

Thus, Gas sweetening plant is a vital unit in the LNG production route. The Gas Sweetening Process in brief. In the Gas Sweetening process, the sour contents present in the feed natural gas are removed by chemical absorption technique. The feed gas for train-3 is HP gas (780 psig); the sour content H 2 S and CO 2 would be at 2.2% and 4.0%.

Gas Sweetening Process Description Essay

Gas sweetening is a process which consists of eliminating toxic elements from the gas extracted from the ground, so that it could be used as an energy source, lowering ecosystem damage It is said that it is relatively friendly with the environment because it produces less amount of waste in its combustion comparing it to other energy sources such as coal, oil, and derivatives.

Gas Sweetening Process Description Essay

The principle process stream is the removal of the acid gases by counter flowing contact with an amine solution, commonly known as Amine Gas Sweetening. The acidic components removed are termed acid gas streams (containing H2S,) and may be flared, incinerated, or converted to elemental Sulphur in a Sulphur Recovery Unit.
