First Class Design for Protection of the Environment
ADSORBENTS
RATE offers proprietary Adsorbents for H2S, CO2, and mercaptan Removal through OEM manufacturing with performance guarantees.
One of the RATE technologies is related to SO2 removal from the tail gas incineration as SETR technology. The SO2 is recovered and it is recycled back to the SRU. The adsorbent for this technology is SETR ADS700. RATE license the technology and supply the Adsorbent.
There are other adsorbents available as regenerable and nonregenerable for H2S removal when the conventional Claus technologies are not economical.
Adsorbents
- Activated Alumina
- Activated Carbon
- Activated Clay
- Molecular Sieves
- Alumino-silicate Adsorbents
- ADS Metal Oxide Based Products
