Uso de CFD na separação do 𝐶𝑂2 utilizando permeação de membranas

Abstract

With the increasing accumulation of greenhouse gases, especially carbon dioxide, mitigation measures must be spread to try to slow down the process of global warming. Among these measures are the capture and storage of 𝐶𝑂2, with the techniques of absorption, adsorption and membrane separation, the gas is captured and destined for new processes. Therefore, a study was carried out on the most common 𝐶𝑂2 capture techniques. A membrane permeation model was studied and simulated, using Fluent software, to evaluate the performance of the separation process of a gas mixture containing 𝐶𝑂2 and 𝐶𝐻4. The results showed the pressure, velocity and concentration gradients involved in membrane permeation. It was concluded that the adaptations carried out in the model influenced the results and that new works increasing the modeling are promising.
