Organic exhaust gas is a major pollutant in many industries. The treatment methods include: condensation method, directcombustion method, Catalytic combustion method, activated carbon adsorption method and absorbing liquid absorptionmethod. The carbon fiber adsorption devices are developed and produced by our company under the guidance of the designunits. The adsorption capacity is better than activated carbon purifier (10~40 times) and the purification efficiency is high (morethan 95%), is featured with easy regeneration, small floor space, corrosion resistance, easy to repair, less auxiliary devices andno secondary pollution. It is especially applicable to the purification treatment on higher concentrated exhaust gases.
