LF828 Molecular sieve 5A
LF828 Molecular Sieve 5A
1 Use
LF828 is used to adsorb H2O, CO2, acetylene and hydrocarbons from air in oxygen production from air; gas and liquid drying; natural gas drying, CO2 and S removal; in PSA process (for separation of O2 and N2, and H2 purification); n-alkanes separation, CO2 and S removal; dewaxing, etc.
2 Regeneration
LF828 may be regenerated and reused by purging or vacuum at elevated temperature, the degree of regeneration is determined by regenerating temperature and regenerating humidity.
