The tail gas treatment unit (TGTU) can purify the tail gas containing sulfide under the action of the catalyst. To achieve the purpose of removing harmful substances and making the exhaust gas discharged into the atmosphere meet environmental protection standards. TGTU and SRU equipment are commonly used in the sulfur recycled and tail gas treating sections of the petrochemical industry.
Read this post to discover how Tail Gas Treatment Units (TGTUs) help refineries meet stringent sulfur recovery and emissions control standards. This blog covers essential TGTU technologies, regulatory requirements, and the vital role that TGTUs play to improve sulfur recovery efficiency.
Maintaining high TGTU performance while lowering reaction temperatures requires extremely active catalysts. Axens’ high activity catalysts will allow reducing inlet temperatures below 220°C with no loss in performance.
A TGTU further reduces the sulfur content in the Claus tail gas to meet more stringent requirements on sulfur emissions. Of the multiple TGTU types and their various configurations, two types are shown in Figure 1. Through different processes, these TGTUs convert residual sulfur species in the tail gas to elemental sulfur and remove it to achieve a higher rate of sulfur recovery.
Introduction The purpose of a tail gas treatment unit (TGTU) is to maximize the conversion of sulfur compounds to H2S. With an eficiently run TGTU, sulfur recovery eficiency can be increased up to 99.99%.
Sulfur Recovery The Claus sulfur recovery unit (SRU) and tail gas treating unit (TGTU) require a suite of process gas analyzers to ensure safe operation, high efficiency, and meet environmental regulations.
A Tail Gas Treatment Unit (TGTU) aims to maximize the conversion of sulfur compounds to H 2 S. The refinery’s sulfur recovery plan t can recover sulfur of the highest purity. The sulfur recovery rate is typically between 94.5~97.5%, although with an efficiently run Tail Gas Treatment Unit, sulfur recovery efficiency can be increased up to 99.99%.
