Implementación de un modelo para la remoción de h2s mediante sorbentes sólidos

The selection of a solid sorbent for the removal of hydrogen sulfide was made from the equilibrium capacity and the selectivity, for some sorbents the selectivity was calculated using Ideal Adsorption Solution Theory (IAST). The PSAC sorbent was the one that showed the best adsorption capacity at 2000 ppm and the NaY zeolite showed a selectivity of hydrogen sulphide in methane of approximately 7000. The implementation of the convection-dispersion model was carried out for a fixed bed column, using the simplification Linear Driving Force and the linear and Langmuir isotherms, for the solution of partial differential equations Method Of The Line (MOL) was used together with the method of the finite differences, with the purpose of predicting the rupture curves of a fixed bed for the removal of hydrogen sulphide from a simulated biogas stream. Modeling was validated with the Klinkenberg analytical solution using 100 steps for the numerical method with a mean square deviation of 0.0029. The rupture curve was also predicted at a concentration of 8.8393x10-2 mol H2S / g ads, and was compared graphically with the experimental data, resulting in the linear model with axial dispersion being adjusted after a time of 150 minutes.
