Q&A: How to deal with a tail gas unit that is performing below spec?

Our tail gas unit is performing below spec. We are experiencing high levels of heat stable salts in the solvent. How do we deal with this?

The presence of heat stable salts does affect the performance of the amine solvent,1 consequently H2 S slip from the absorber may increase dramatically. To bring the H2 S slip back to acceptable levels, the amine solvent needs to be restored back to pristine conditions, either by a reclaiming process or by partial or full replacement.
