| The traditional method for determining a periodic state (cyclic steady state) of an adsorption cycle (e.g., PSA or TSA) from a mathematical model involves simulating a process through successive cycles until the solution is not changing very much from cycle to cycle. We have developed methods based on nonlinear analysis to determine the periodic states directly. These will be described in the paper including our new specialized software for accelerated convergence and optimization. We will also describe interesting properties of the periodic states including stability and multiplicity. |
