Introduction
Chemxin molecular sieve type 5a is an alkali alumino silicate; it is the calcium form of the type a crystal structure. Type 5a has an effective pore opening of 5 angstroms (0.5 nm). It will adsorb molecules with a kinetic diameter of less than 5 angstrom and exclude those larger.
It is especially suitable for psa adsorber applications where it may be used for the separation of normal- and iso- paraffins (c4 to c6 species), in psa hydrogen purification and in oxygen concentrators.
Regeneration
Chemxin molecular sieve type 5a 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 5a 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 ppm.
The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.
Size
5a - 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 1.6mm, 3.2mm.

Plastic Cascade Mini Ring is made from heat resistant and chemical corrosion resistant plastics, including polyethylene (PE), polypropylene (PP), reinforced polypropylene (RPP), polyvinyl chloride (PVC), chloridized polyvinyl chloride (CPVC) and polyvinylidene fluoride (PVDF). It has features such as high free volume, low pressure drop, low mass-transfer unit height, high flooding point, uniform gas-liquid contact, small specific gravity, high mass transfer efficiency and so on .The application temperature in media ranges from 60¡ãCto 150¡ãC. For these reasons it is widely used in the packing towers in petroleum industry, chemical industry, alkali-Chloride industry, coal gas industry and environmental protection, etc. Applications: Absorption and stripping services Many environmental applications Place of Origin Jiangxi, China (Mainland) Brand Name Kelley Model Number K-PCMR Size 16.25.38.50.76mm Certificate ISO9001:2000 Materials PP PE PVC CPVC PVDF Shape tower shape. 1.)25kg woven bags+pallet,ton bags with wooden pallet. 2.)cartons +pallets. 3.)packed as per customer's request.
Ceramic saddle is improved from the arc saddle, ceramic saddle changes the both arched surface torectangular surface and makes the interior radius of curvature different, this construction overcomes the problem of nesting basically, ceramic saddle makes porosity distributed even and improves the distribution of the fluid, greater capacity and lower pressrue drop than rasching ring.
