Simulation of pressure swing adsorption process
This paper focuses on modeling of pressure–temperature swing adsorption (ptsa) process in a commercial two-layer adsorption system during sequential steps of cyclic operation to remove water from natural gas. The objective of the software is to enable process simulation and optimization for a large range of industrial gas adsorption processes such as cyclic processes (pressure-swing adsorption, temperature-swing adsorption) the software will allow the selection of optimal adsorbents, the design of improved adsorption cycles, and the improvement. Cyclic separation processes such as pressure-swing adsorption are fundamental to high-purity gas production however because of the cyclic – and thus inherently dynamic – nature of the operations, they are very difficult to design, with the numerical challenges of solving such systems poorly catered for by current simulation software. In this paper, an optimisation-based approach is developed for the determination of the cyclic steady-sate (css) of a pressure swing adsorption process (psa) it consists in treating the simulation problem as a single dynamic optimisation problem where the performance index is the css condition, the. With the growing maturity and accuracy of bed models for adsorption, increasing sophistication of pressure swing adsorption (psa) cycles and competitive demands for high‐performance psa separations, it is essential to develop systematic optimization strategies for the design of psa systems.
