THEORETICAL-ANALYSIS OF HIGH AND LOW-TEMPERATURE SHIFT CONVERTERS

A theoretical analysis is performed to study the catalytic reaction of CO in both high and low temperature shift converters, The study inclu des comparison between model predictions and data collected from local industries in Kuwait. Theoretical models are developed to simulate te mperature and conversion profiles of CO in both the high and low shift converters. Good fits are obtained between the theoretical prediction s of exit CO conversion and axial temperature profiles and the collect ed data. Calculations show the existence of an optimum feed temperatur e for the high temperature shift converter. Such an optimum does not e xist for the low temperature shift system because of physical limitati ons on operating conditions.
