Activated Alumina For Deep Drying Of Cracked Gas, Ethylene And Propylene
Products Introduction:
The activated alumina balls as deep drying used as the dryer for some industries such as oxygen industry, textile industry, gas drying in electronics industry, air drying in automation instruments, as well as dryer and decontaminating agent for fertilizer, petrochemical and other industries (dew point can be up to -40 degrees), in air separation, the dew-point adsorption of pressure change can up to -55 degrees. It is a highly effective dryer for dry deeply in micro-water. It is an ideal dryer for non-thermal regeneration device.
