Product Description
Molecular Sieve type 3A is an alkali metal alumino-silicate; it is the potassium form of the type A crystal structure. Type 3A has an effective pore opening of about 3 angstroms (0.3nm). This is large enough to allow in moisture, but excludes molecules such as unsaturated hydrocarbons which can potentially form polymers; and this maximises lifetime when dehydrating such molecules.
Typical Chemical Formula
0.45 K2O . 0.55 Na2O . Al2O3 . 2 SiO2 . 4.5H2O
SiO2 : Al2O3 ≈2
Application
Drying of unsaturated hydrocarbons (e.g. ethylene, propylene, butadien)
Cracked Gas Drying
Drying of natural gas, if COS minimization is essential, or a minimum co-adsorption of hydrocarbons is required.
Drying of highly polar compounds, such as methanol and ethanol
Drying of liquid alcohol
Static, (non-regenerative) dehydration of insulating glass units, whether air filled or gas-filled.
Drying of refrigerants
Regeneration
molecular sieve Type 3A 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 3A molecular sieve, a temperature of 200-230°C is required. A properly regenerated molecular sieve can give moisture dew points below -100°C.
The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.
Size
3A - 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.
Pingxiang Global Chemical Packing Co., Ltd. (PGCP), is located in Gaokeng Industrial Park, Pingxiang, Jiangxi Province. It can produce ceramic, metallic and plastic tower packings, ceramic balls, molecular sieves, catalysts, activated alumina, petrochemical additives, activated carbons and filtering materials etc. Used in chemical and petrochemical industries.
Since established, the PGCP has made great achievements, developed a lot of new products, acquird the certificate of ISO9001-2000 and set up a pleasant cooperative relationship with the wide circles of the users, material suppliers, scientific research institutes and engineering design institutes. In 2006, we drafted chemical industry standards HG/T3986-2007 for Technology Condition of Plastic tower packing and HG/T3927-2007 for Industrial Activated Alumina with the National Non-metallic chemical equipment Standards Committee and the National Chemical Standard Committee. Our general engineer took part in drafting national chemical industry standard, that is HG/T 3683.1-2000 Industrial Ceramics Ball-Inert Ceramics Ball and HG/T 3683.3-2000 Industrial Ceramics Ball-Perforated Ceramics Ball. The new developing products HQ-HK slotted & perforated ceramic balls, high efficiency HQ-HK slotted & perforated supporting agent and high efficiency HQ-HK slotted & perforated protecting agent have the national patent, the number is ZL2005 3 0048184.0. Besides these ones, we have other patent products, that is HQR ring (ZL 2005 3 0048180.2) and HQ eight columns arcs link (ZL2006 3 0147956.0).
