The most common methods involve using and absorption tower with water or an amine solution.
Aqueous solutions of various alkylamines (commonly referred to simply as amines) are used to remove hydrogen sulfide(H2S) and carbon dioxide (CO2) from the gas stream. This process is referred as gas absorption.
These gases are well-known green-house gases. Non-thermal plasma (DBDs) can possibly be used to promote chemical reactions to reduce the emission of these gaseous pollutants.
Yes we can make separation of H2S and CO2 using chemical absorption tower and the solvent can EthanolAmine

CO2 and H2S remotion is performed generally by gas absorption as point by the other researchers here. Normally H2S is more soluble than CO2 and can be removed together. There are several absorbing liquids used for that. The choice normally depends on process conditions like pressure, concentration and volume to be treated and the removal necessary. For biogas for instance,due low concentration of H2S, low pressure and volume to be treated,water can be used.
