Formatted abstract
This inquiry involved the development of an ASPEN model for the purposes of simulating the Sulfinol process for CO2 removal at Incitec Pivot’s ammonia plant. The Sulfinol process is base on an amine chemical absorption stripping system, developed by the Shell Corporation.

The development of the model was required to assist in the determination of what the process limitations were to increasing the ammonia plants production by 18%.

The main requirement of the modelled absorption stripping system was to realistically match the plant conditions and accurately predict the plants operational outputs. This included the absorption of 99.99%w/w of CO2 and use of an aqueous solution of DIPA with a maximum concentration of 52%w/w.

The constructed model was then validated using numerous diagnostic tests to prove that it was accurately representing the Sulfinol process. This validation phase involved comparing the model results against the existing plant data, which in turn provided information on potential problem areas regarding bottlenecks within the current Sulfinol process.

The model was then used to determine the CO2 removal efficiency at higher Sulfinol solution flowrates. This would be required if the ammonia plants increased production targets are to be achieved.
