REMARKS: |
Material Confirms specification of our Grade A: 101 for desiccant applications when tested as per IS: 9700:1991 |
Size Tolerance: Undersize/Oversize: Less than 5%. |
Possessing higher capacity for water as compared to silica gel at elevated temperatures, it acts as desiccant for warm gases including air. Having surface area in the range 345-415 m2/gm these find wide application in :
Drying of organic liquids such as LPG, propylene, butene, steam cracked liquids, cyclohexane, gasoline, chloro- and fluorohydrocarbons, aromatic solvents
Drying of air and gases such as steam cracked gases, catalytic reforming recycle gas, synthesis gas, natural gas, CO2
Drying of organic liquids as LPG, aromatics, steam cracked liquids, gasoline, chloro- and fluorocarbons
Drying of air and gases as steam cracked gases, catalytic reforming recycle gases, synthesis gases, methyl chloride, natural gas, LNG, etc.
Drying of hydrogen, oxygen, nitrogen, CO2, etc
Purification of gases and liquids (removal of metallic traces, TBC and HF compounds) • Purification of gases and liquids (removal of metallic traces, BF3, TBC, HCl, HF and fluorinated hydrocarbons)
Catalyst for Claus conversion in sub dew point processes
Air drying (PSA, TSA)
Instrument air, supersonic wind tunnel, compressed air
Gas drying Air separation plants, inert and rare gases, Hydrogen, oxygen, nitrogen, CO2
Aromaatics, naphtha cuts and cracked gas
Natural gas in production and compression plants, LPG, LNG
