Designing a selective MDEA tail-gas treating unit

Following these protocols will enhance sulfur recovery efficiency

Nagpal, S., Fluor

Selective amine-based Claus sulfur recovery units (SRUs)–tail-gas treating units (TGTUs) have become the preferred option for enhancing sulfur recovery efficiency to above 99.8% while minimizing sulfur emissions. The most commonly used selective amine is a generic methyl diethanol amine (MDEA). The most commonly known process is the SCOT process. Over 400 such plants have been built and many others are under construction that are using the SCOT process. The TGTU process represents an extreme operating scenario for an amine gas-sweetening unit. While the TGTU process configuration is similar to a typical amine absorption-regeneration system, both the absorber and regenerator operate at
