1.DEscriptION:
TOP-HgSiv-3 adsorbent is a silver-loaded type A Molecular sieve specially formulated to adsorb mercury
(Hg), as well as molecular with critical diameters up to Approximately 3 angstroms.
2.APPLICATIONS:
TOP-HgSiv-3 adsorbent is used to remove low levels of Mercury form olefinic or reactive process streams, such
As cracked gases and liquids containing H2S.It can be Installed in existing molecular sieve dehydration /
Purification units to remove mercury, along with water And other impurities.TOP-HgSiv-3 adsorbent is capable
Of providing a mercury concentration of less than 0.01μg/ Nm³ (micrograms per normal cubic meter) .
3.CHEMICAL FORMULA:
Mx [(AlO2)x(SiO2)y] •a Ag2O •z H2O [M=Na, K]
4.REGENERATION:
TOP-HgSiv-3 adsorbent can be regenerated for reuse By purging or evacuating at temperatures of
400ºF to 450ºF.The mercury is rejected the Regeneration fluid.
5.SAFETY AND HANDLING:
See the TOP brochure entitled "Precautions and Safe Practices for Handling Molecular Sieves in Process
Units" or contact your TOP representative.
6.SHIPPING INFORMATION:
TOP-HgSiv-3 adsorbent is shipped in 55-gallon steel Drums or quick load bags.
