Chemical absorption of H2S for biogas purification

M.S. Horikawa; F. Rossi; Marcelino Luis Gimenes; C.M.M. Costa; M. G. C. da Silva

This work presents an experimental study of purification of a biogas by removal of its hydrogen sulphide (H2S) content. The H2S was removed by means of chemical absorption in an iron-chelated solution catalyzed by Fe/EDTA, which converts H2S into elemental sulphur (S). Preparation of the catalyst solution and the results of biogas component absorption in the catalyst solution (0.2 mol/L) are presented. These results are compared with those for physical absorption into pure water under similar conditions. Experimental results demonstrate that, under the same experimental conditions, a higher percentage of H2S can be removed in the catalytic solution than in water. In a continuous counter current using adequate flow-rate phases contact at room temperature and low gas pressure, the results demonstrate that is possible to totally remove the H2S from the biogas with the prepared catalytic solution.

The use of clays for adsorption of heavy metals in wastewater has been studied in many trials because of numerous technical and economic advantages. This work aimed to evaluate the removal of nickel and zinc in fixed bed column. The experiments for the removal of nickel and zinc were conducted at room temperature (20 oC - 25 oC), pH adjusted at 4.5, weight of 15.5 g calcined clay,with an average diameter of 0.855mm, feeding flow rate 4 mL/min and concentration of the solution of metal between 0.5 meq/L to 4 meq/L. The Langmuir, Freundlich, Langmuir-Freundlich, Radke-Prausnitz, Redlich-Peterson, Sips and Toth models were fitted to equilibrium data, and the Langmuir model provided the best fit for adsorption isotherms.
