Abstract:

A two-dimensional multiphase Computational Fluid Dynamics model has been developed in this work to describe the concentration profiles of the different species involved in a biogas upgrading column based on sodium hydroxide – carbon dioxide reaction. The model uses the Volume-Of-Fluid approach for gas-liquid interface tracking and an external User-Defined Function in order to account for the chemisorption of carbon dioxide into the liquid solvent. The model allows for quantification of the unreacted sodium hydroxide in the liquid solvent; and can be further used to set up the operating parameters in order to maximize the efficiency of the process.
