1) Removal of CO2 and moisture from air (air pre-purification) and other gases.
2) Separation of enriched oxygen from air.
3) Removal of mercaptans and hydrogen sulphide from natural gas.
4) Removal of mercaptans and hydrpogen sulphide from hydrocarbon liquid streams (LPG, butane, propane etc.)
5) Catalyst protection, removal of oxygenates from hydrocarbons (olefin streams).
6) Removal of n-chained compositions from aromatics.
7) Production of bulk oxygen in PSA units .
8) Production of medical oxygen in small scale oxygen concentrators
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
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.
To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
Pingxiang Naike Chemical Industry Equipment Packing Co., Ltd. (also known as NKCHEM), the top leading mass transfer product manufacturer of tower packing (column packing) and chemical ceramic. NKCHEM was established from the consortion of several existing factories with a long history.
NAIKE Molecular Sieves are normally used in the process of drying gases and liquids.Molecular Sieves are a crystalline composition with uniform pores that is measured in angstroms.
This composition makes Molecular Sieve more effective than other types of desiccants.
Molecular Sieve Desiccants are extremely effective at removing water from liquids and gases. They are even more effective silica gel or activated alumina, because of their crystalline composition; they can create virtually water-free products. These sieves are veryuseful in cryogenic operations where liquefaction of gases is required and water must be eliminated to avoid freezing.
Molecular sieves offer a variety of adsorption selectivity based on molecular size. molecular affinity for the sieve crystal surface, and shape of the molecule. Using this type of system is exceptionally uncomplicated for diminishing impurities to practically indiscernible levels compared to other liquid separation systems. The ease of use and superior efficiency when compared to other adsorptionsystems makes the most popular engineering solution a molecular sieve system.
Molecular sieves are used for drying gas streams with in the petroleum industry; used todry solvent within a laboratory along with a extensive range of catalytic applications. Additionally, Molecular Sieves are used in a great many air filtration and liquid filtration scenarios.
