THERMODYNAMIC MODELING OF THE HIGH TEMPERATURE WATER GAS SHIFT REACTOR IN BASRA FERTILIZER PLANT....

The State Company of Fertilizers South Region's high-temperature Water Gas Shift (WGS) reactor has significant technological significance for minimising CO content during the conversion of synthesis gas to hydrogen. It is an essential component of the ammonia plant. To calculate the equilibrium composition of the shift process, a simulation software based on the Peng–Robinson Equation and the Gibbs free energy minimization method is constructed. The impacts of operating factors such as reaction temperature, pressure, and steam to gas ratio S/G on CO conversion and hydrogen production were investigated using Aspen-HYSYS to undertake a thermodynamic analysis of the water gas shift (WGS) process from synthesis gas. The highest CO conversion and H2 output are achieved at low temperatures and low steam to gas ratios (S/G), according to simulation data. The simulated model's conclusions are in good agreement with the available industry data.
