Technologies like RATE SMAX and SMAXB consists of 3 or 4 stages Claus unit and using SMAX-100, SMAXB-100 proprietary and patented catalysts can achieve up to 99.5% sulphur recovery without any tail gas treating unit. These are direct reduction and direct oxidation catalysts.
If caustic scrubbing or SETR technology is added after the incineration, Zero SO2 emission can be achieved. The technology licensing and the catalysts are offered together for any grass roots or revamp of the existing SRU.
The Claus units require alumina, titanium, promoted alumina and oxygen scavenger and RATE tail gas treating units require conventional COMO, low temperature, low pressure drop hydrogenation catalysts, all are offered by RATE directly.
Adsorbent is a cost-effective non-hazardous iron hydroxide based adsorbent specifically designed for removal of H2S and mercaptans from CO2, natural gas, biogas, shale gas production, and other gasses for total sulphur control. It is comprised of a high porosity mixed iron oxide form.
