Troubleshooting tail gas amine treaters

摘要

Simulation can play a key role in troubleshooting the performance of a tail gas-treating unit contaminated with sodium and heat-stable salt anions.Comparisons can be made between plant performance data and simulations that assume clean amine,allow HSSs just to inactivate part of the amine,and fully account for the effect of HSSs and alkali metal ions on the chemistry of the system.The outcome demonstrates unequivocally that simulation accuracy is predicated upon accurate solvent analysis.
