Zeolite Molecular Sieve 13x 4*8mesh Beads For Natural Gas Drying And Desulfurization
Product Description
Xi'an Lvneng 13X is the sodium form of the type X crystal and has a much larger pore opening than the type A crystals. It will adsorb molecules with a kinetic diameter of less than 10 Angstrom (1.0 nm) and exclude those larger. It also has the highest theoretical capacity of the common adsorbents and very good mass transfer rates. It can remove impurities too large to fit into a type A crystal and is commonly used to separate nitrogen from oxygen.

Typical Application
a) Removal of CO2 and moisture from air (air pre-purification) and other gases.
b) Separation of enriched oxygen from air.
c) Removal of n-chained compositions from aromatics.
d) Removal of R-SH and H2S from hydrocarbon liquid streams (LPG, butane etc.)
e) Catalyst protection, removal of oxygenates from hydrocarbons (olefin streams).
f) Production of bulk oxygen in PSA units.
Regeneration:
Xi'an Lvneng molecular sieve Type 13X can be regenerated by either heating in the case of thermal swing processes; or by lowering the pressure in the case of pressure swing processes.
To remove moisture from a 13X molecular sieve, a temperature of 250-300°C is required. A properly regenerated molecular sieve can give moisture dew points below -100°C, or mercaptans or CO2 levels below 2 ppm.
The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process
