Abstract

An alternative fuel that has emerged today is natural gas. Natural gas is a mixture of gaseous hydrocarbons formed mainly by methane. However, because it is found in natural underground deposits, it is accompanied by various impurities or contaminants, among which are the acid gases H2S and CO2 that cause corrosion in the lines and process equipment, making its distribution difficult, reducing its energy power and increasing toxicity in the gases emitted during combustion.

For the removal or elimination of these acid compounds from the gas, absorption-desorption systems using a selective solvent are used. The fed gas is called "bitter", the product "sweet gas", and the process is generally known as "sweetening". There are several patents to carry out the natural gas sweetening process, which differ in the type and composition of the solvent used.

The increase in the demand for natural gas makes it necessary to improve the sweetening process, by increasing the production of sweet gas and reducing operating costs. Studies carried out in this area are aimed at reducing amine losses, through the manipulation of operating variables and the implementation of devices, obtaining excellent results in cost savings without altering the capacity or quality of sweetening.

As already proven, amine blends are the best method to increase capacity or improve efficiency in sweetening units. Currently the focus is directed towards secondary and tertiary amines, particularly on the use of mixtures of diethanolamine (DEA) and methyldiethanolamine (MDEA) to carry out CO2 separation. You can work with any mixture of amines in aqueous solution or you can add a physical solvent to it for study.
