1.3 Objectives and Outline The purpose of the present work is to provide a breakthrough model that could be used in PSA processes employing columns with more than one layer of different adsorbents. Two different isotherm models are being incorporated in gPROMS® libraries, with the purpose of being employed in simulations concerning multilayer adsorption columns. With the aim of validating the models, data from the literature present in chapter two is going to be used in the breakthrough simulations. A tool present in gPROMS, parameter estimation tool, is going to be employed with the purpose of estimating the Linear Driving Force parameters, as well as, isotherm parameters in order to evaluate the capacity of this tool in predicting parameters related with a breakthrough simulation with multilayer adsorption bed. This work is outlined as follow: In chapter two a brief introduction of the main concepts of Pressure Swing Adsorption is presented along with some concepts of the adsorption process. Several industrial and Lab scale processes concerning multilayer PSA systems are described. Chapter three contains the main equations of the mathematical model inserted in gPROMS® adsorption libraries and, a brief description on gPROMS® tool is made. In chapter four the modelling done is presented as well as the breakthrough simulations and validations. Parameter Estimation of the LDF coefficients and isotherm parameters using the developed models is also performed and presented in this chapter.
