Mercaptans removal from sour natural gases has always been considered as a challenge, as the solvent processes, which are very well adapted to the treatment of large quantities of sour gases, have a poor ability to remove these organic sulfur compounds together with H2S and CO2. This question is even becoming more important due to the global trend towards more stringent total sulfur specifications for commercial gases.
