| Abstract: | An interactive program based on the Gibbs free energy minimization and the FLOWTRAN system analysis was written to simulate various schemes of the Claus process. Dew point calculation and feedback control loops were provided. Certain species are treated as inerts in units like condensers, reheaters, and the waste heat boiler, Simulation of the Claus process air demand and simulation of two Claus plants (including a commercial one) were presented and the results analyzed. |
