Molecular Sieve 13X for Air Seperation and Oxygen Production PSA Unit
DESCRIPTION:
Molecular Sieve 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 9 Angstrom (0.9 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 CHEMICAL FORMULA:
Na2O. Al2O3. (2.8± 0.2) SiO2. (6~7)H2O
SiO2: Al2O3 ≈ 2.6-3.0
APPLICATION:
1) CO2 and moisture Removal from air (air pre-purification) and other gases.
2) Production of bulk oxygen in PSA units.
3) Separation of enriched oxygen from air.
4) Production of medical oxygen in small scale oxygen concentrators
5) Mercaptans and hydrogen sulphide Removal from natural gas.
6) Removal of mercaptans and hydrpogen sulphide from hydrocarbon liquid streams (LPG, butane, propane etc. )
7) Catalyst protection, removal of oxygenates from hydrocarbons (olefin streams).
8) Removal of n-chained compositions from aromatics.
REGENERATION:
JINCHENG 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 mercaptan or CO2 levels below 2 ppmv.
The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process
SIZE AVAILABLE:
13X - Zeolites are available in beads of 1-2 mm, (10x18 mesh) 2-3 mm, (8x12 mesh), 2.5-5 mm, (4x8 mesh) and as powder, and in pellet 1.6, 3.2.
ATTENTION:
To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
