SENSITIVITY ANALYSIS OF A FIXED-BED GAS-SOLID TSA - THE PROBLEM OF DESIGN WITH UNCERTAIN MODELS

In this paper the analysis of the effects of model uncertainties on pr edictions is reported for a multi-component gas-solid TSA fixed-bed ad sorber. Owing to the complexity of the system the study was carried ou t by means of a simplified method. Despite its simplicity this method allowed the evaluation of the effectiveness of predictions and the ide ntification of the most critical aspects of the model, which require i mprovement in order to obtain reliable model outputs. The advantages o f such an analysis are that the results can be used to improve the rel iability of the model and make the model useful for good design and sa fety considerations.
