Tail gas treating unit
Web25 Oct 2024 · October 25, 2024 What Is Tail Gas? Tail Gas, or SRU Tail Gas, is the final gas stream leaving a Sulfur Recovery Unit after most of the Hydrogen Sulfide (H 2 S) has been removed. A typical SRU operating at design conditions can remove between 95-97% of the incoming sulfur in the feed stream. WebThe tail gas catalyst bed temperature was raised to a minimum of 420°F (215.56°C) before adding H 2 S-containing gas to the TGTU. Plant nitrogen was used as the process gas to heat the catalyst. MDEA solution was circulated for 5 d before any H 2 S-containing gases were routed to the new TGTU.
