SUMMARY:

Biogas has a huge potential for applications, which can be of the most varied. The high content of methane in its composition makes it an extremely interesting gas for use as a source of thermal energy. However, the presence of hydrogen sulphide poses a problem for the use of biogas. Taking into account the rural context in Brazil, the benefits that can be obtained by the application of technologies based on biogas can be immense, but first of all, it is necessary to be concerned with safety in the use of this mixture of gases, then methods for removal of hydrogen sulphide become of great interest, mainly methods that are accessible, given the difficulty of access to products and equipment to carry out the removal process. Industrially, there are already some well-known and widespread methods for the removal of hydrogen sulfide, highlighting chemical absorption, through the use of amines in the process, which can then be recovered, but bringing to the context of the brazilian semi-arid, industrial methods, despite being effective, require a large amount of resources in this context. Using a sodium hydroxide solution as a solvent in the hydrogen sulfide absorption process presents itself as an alternative that can have a good application potential, both in terms of cost and in terms of reagent accessibility, thus determining better operating conditions, using experimental planning techniques to carry out the experiments, is very important in the application and diffusion of this type of technology.
