Paraxylene is an essential chemical compound used in the production of polyester fibers and plastic materials. As the demand for this compound increases, the need for efficient separation and purification techniques also rises. Adsorption towers using molecular sieve have been widely used for paraxylene separation. The separation of paraxylene from other components in a mixture of xylene isomers is a complex process that requires the use of adsorption towers filled with molecular sieves. However, the continuous operation of such towers leads to deactivation of the molecular sieve, resulting in decreased efficiency and higher operating costs. In this project, it is proposed to simulate the paraxylene adsorption tower and develop a deactivation model for the molecular sieve to optimize the tower's efficiency.
