• Resumen

  • Two prosperous biotechnological processes have been developed for H2S removal from gaseous streams. These processes can be categorized into acidophilic and alkalophilic processes based on operating condition applied. Both processes are based on the combined action of a chemical absorption step and a biological step for regeneration of the absorbent solution used. Elemental sulfur is the end product. In this paper the feasibility and engineering aspects of theses two processes are discussed and a comparison between both processes is presented.
