Pressure swing adsorption (PSA) is a process for separating gas mixtures based upon recently developed adsorbent solids capable of selectively retaining specific gases. The major operating parameter in a PSA system is pressure; most commercial units operate at, or near, ambient temperature.

Mass transfer kinetics in pressure swing adsorption
Separation and Purification Technology, 2000Many mass transfer kinetic models are used to study varying pressure steps of a pressure swing adsorption (PSA) cycle, namely pressurization and blowdown steps. It is shown that the choice of an appropriate model to account for intra-particle diffusional limitations is essential to simulate accurately PSA processes.

The upgrading of biogas by pressure swing adsorption (PSA) was studied. Simulations of a process for binary separation of CH4−CO2 using zeolite 13X as selective adsorbent were carried out at 323 K. The results obtained with a two-column PSA process using a six-step cycle (pressurization, feed, depressurization, blowdown, purge, and pressure ...

Non-Diffusive Models for Pressure-Swing Adsorption
IMA Journal of Applied Mathematics, 1988This paper examines the industrial process popularly known as ``pressure- swing adsorption'' from both analytical and numerical points of view. After a derivation of the equations of motion and a description of the important stages involved in the process it is shown that for the case of a binary mixture the problem may be treated analytically in ...

Process intensification in duplex pressure swing adsorption
Computers & Chemical Engineering, 2011Abstract As an alternative to the Pressure Swing Adsorption (PSA) based on the Skarstrom cycle or its variants, a novel two-bed PSA – called duplex PSA – has been proposed by Hirose and independently by Leavitt to get both products of high purities. A modified duplex PSA has been presented to achieve process intensification, that is, to enhance the ...

The optimal design of pressure swing adsorption systems
Chemical Engineering Science, 1991Abstract This work presents a model to determine the annualized cost optimal design of a pressure swing adsorption (PSA) separation system. Design decisions include the number of beds the operations to use, the scheduling of those operations, and the operating conditions. Operations include adsorption, pressure equalization, blowdown, desorption, and

Oxygen Production by Pressure Swing Adsorption
Separation Science and Technology, 1989Abstract The specific oxygen production capacity and the oxygen recovery of a pressure swing adsorption (PSA) process for the production of oxygen from ambient air by selective adsorption of nitrogen can be increased by operating the process at a superambient temperature.
