No obstante, a partir de hidrógeno se está empezando a aplicar a lo relacionado con esta última sustancia, sobre todo como fuente de energía.

Carbonation occurs when carbon dioxide is dissolved in water or an aqueous solution. This process is generally represented by the following reaction, where water and gaseous carbon dioxide react to form a dilute solution of carbonic acid. [H2O + CO2=H2CO3] This process yields the "frizz", to carbonated water, the head to beer, and the cork pop and bubbles to champagne and sparkling wine. Carbonation is used to improve both the taste and "texture" of the carbonated consumable. Carbonation is sometimes used for reasons other than consumption, to lower the pH(raise the hydrogen ion concentration) of a water solution...  2, record 6, English, - carbonation

To maximize isotopic exchange, it is very important that the [hydrogen sulphide] in the units be maintained at a very high purity(99. 5%). Unfortunately, the natural water, although treated, still contains small quantities of dissolved oxygen, carbon dioxide, nitrogen, and other gases. If not removed continuously, these gases would accumulate and decrease the [hydrogen sulphide] purity. A continuous gas purge is drawn from the top of each firs stage cold tower and send to the purge tower where the [hydrogen sulphide] is absorbed by the incoming water. The gaseous impurities proceed from the purge tower to the absorber where any remaining [hydrogen sulphide] is absorbed. The gases, essentially [hydrogen sulphide] free, are then flared. The flare is used in this case to burn any [hydrogen sulphide] that might not have been absorbed.  1, record 26, English, - gaseous%20impurity

Lavage de gaz : le gaz sous pression, par exemple des hydro-carbures gazeux contenant de l'hydrogène sulfuré ou du gaz carbonique, rencontre à contre-courant une solution d'éthanolamine dans la colonne (colonne à plateaux, garnissage spraypack, etc). La solution introduite au sommet de la colonne a été régénérée et contient un minimum de gaz acide. Avant d'être évacué, le gaz traverse un dévésiculeur, matelas métallique par exemple, qui évite les entraînements liquides. La solution extraite à la base, riche en [gaz carbonique] et [en hydrogène sulfuré] est envoyée après réchauffage dans une colonne de régénération (également à plateau ou garnie) ou elle est débarrassée des gaz acides. La température dans cette colonne est supérieure à 100 °C.  2, record 26, French, - impuret%C3%A9%20gazeuse
