Product Description
3A Molecular Sieve for Ethano-l Dehydration 
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 maximizes lifetime when dehydrating such molecules.

Typical Application Drying of unsaturated hydrocarbons (e.g. ethy-lene, propylene, butadien)
Cracked G-as 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 metha-nol and ethan-ol
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.

Fipronil is a broad-spectrum insecticide that belongs to the phenylpyrazolechemical family. Fipronil disrupts the insect central nervous system byblocking GABA-gated chloride channels and glutamate-gated chloridechannels. This causes hyperexcitation of contaminated insects' nerves andmuscles. Fipronil's specificity towards insects is believed to be due to itsgreater affinity to the GABA receptor in insects relative to mammals and itseffect on GluCl channels, which do not exist in mammals.Fluoronitrile is a broad-spectrum insecticide with excellent control effect on many kinds of insect pests. It is highly sensitive to hemiptera, lepidoptera, thysanoptera, coleoptera and other insect pests as well as pests that have become resistant to pyrethroid and carbamate insecticides.It can be used to prevent and control various crop pests and sanitary pests such as rice, vegetables, cotton, tobacco, potato, sugar beet, soybean, rape, tea, alfalfa, sugarcane, sorghum, corn, fruit trees, forest, ornamental plants, public health, animal husbandry, storage products and ground buildings.
