Simulation of Pressure Swing Adsorption Process of Butane/Air Separation in Carbon-Coated Ceramic Monolithic Adsorber

چکیده
The new shaped structured adsorber, carbon monolithic adsorber, are characterized by straight parallel channels separated by thin wall, high void fraction and large geometric surface area, resulting in a low pressure drop under high flow rate and large contact area. These properties make it have the advantage on adsorption application. This study simulates the adsorption separation of 30% butane and 70% air on carbon-coated ceramic monolithic adsorber for a three-step pressure swing adsorption process under isothermal condition. The parameters considered in the model include the mass transfer coefficient to the channel wall, effective diffusion within the pore structure and axial dispersion model. The model analyzes the effect of variables such as, carbon-coated wall thickness, feed pressure, etc. on the performance of pressure swing adsorption.
