Pressure Swing Adsorption Technology Using 5A Zeolite for the Removal of H₂S in the Fixed Bed Reactor

Abstract

Proposed model for H2S was analyzed using a stationary adsorbent bed allowing continuous operation. The numerical method of inverse Laplace transform was used to solve the one-dimensional isothermal mathematical model that describes the process. For the simulation, a computer code in Fortran 90 language was developed to solve the problem in dynamic regime. The objective of this research has been to formulate a robust mathematical model for the adsorption process of H2S on nanostructured solid (NaX) at 25 °C and pressures at 1.01 bar. The adsorption capacity of catalytic adsorbent using H2S has been analyzed as well as the simulation of H2S in liquid and solid phases for different initial superficial velocities.
