| d) Static, (non-regenerative) dehydration of insulating glass units, whether air filled or gas-filled. | ||||
5A molecular sieve Application Areas
Natural gas processing:
Drying: Removes moisture from natural gas to prevent corrosion of pipelines and equipment.
Desulfurization and decarbonization: Improve the purity of natural gas to meet industrial and civil standards.
Gas separation:
Nitrogen-oxygen separation: producing high-purity nitrogen and oxygen in an air separation device.
Nitrogen-hydrogen separation: Used in processes such as ammonia synthesis to separate nitrogen and hydrogen.
Petrochemicals:
Petroleum dewaxing: Separating n-hydrocarbons from branched and cyclic hydrocarbons to improve oil quality.
Separation of normal and isoalkanes: improves the octane and cetane numbers of fuels such as gasoline and diesel.
