UOP HgSIV™ Regenerable Mercury Removal is a proprietary Honeywell UOP licensed technology in which silver-impregnated molecular sieve (HgSIV™) adsorbent is loaded into an existing TSA (Temperature Swing Adsorption) molecular sieve dehydrator. Dehydration and mercury removal are performed simultaneously in the same vessels. Mercury is adsorbed during the online (drying) step and thermally desorbed during the normal regeneration cycle, so the sorbent is continuously refreshed each cycle. The technology can be applied to both gas and liquid hydrocarbon streams.
