WHA-100,101,102,103 Active Aluminum Oxide Dryer

1. Chemical formula: Al2O3•nH2O n< 1
2. The properties and uses
     This kind of product is X-ρ form active aluminum oxide dryer.Its appearance is white spheric particle with strong adsorptive capacity of moisture,its drying depth(dew point)can be below-70°C under certain operating and regenerating conditions.It is a high efficiency dryer for drying micro amount water.This product is widely used as dryer in gas phase,liquid phase and auto-instrument wind drying of petrochemical,textile and oxygen-making industries,PSA in air-seperation etc..Due to high heat-adsorption quantity of single molecular adsorbing layer,so,it is very suitable for the use of heat-free regeneration device.
This product is appraised by the Ministry of Chemical Industry.The main technical indexes can reach the level of PSG-A product made by France.This product is appointed as the first batch substitute imported product by China Petrochemical General Corporation and has awarded the title of "Superior Product" and "Good Horse" prize of Zhejiang province.

4.PRECAUTIONS: (1)Don't unpack the product before use,in order to avoid moisture adsorption and efficiency decrease of use;
(2)The product is suitable for deep drying with the pressure over 5kg/cm2;
(3)The absorptivity ability will decrease gradually with the product used after a certain time,in order to use it repeatedly the product should be regenerated to remove the adsorptive moisture. The gases used for the regeneration should be:
①The dried gas with lower or same operating pressure of drying operation;
②The dried gas with higher or same temperature of drying operation;
③Wet gas after rising temperature;
④Wet gas after reducing pressure.
