Amine strength in gas treatment
Tail gas treating units (TGTUs) are designed to remove the last vestiges of unconverted hydrogen sulfide (H2S) in the tail gas coming from a sulfur recovery unit (SRU) after the gas has been processed to convert as much H2S as possible to elemental sulfur. Any H2S remaining in the TGTU’s offgas is converted to sulfur dioxide (SO2) in the thermal oxidizer and vented to the atmosphere. This vented SO2 forms part of a plant’s regulated sulfur emissions, so it is important to minimize its amount.
