SCREENING AND RESPONSE SURFACE MODELING OF WATER VAPOR ADSORPTION FROM WET AIR IN PACKED BED OF SILICA GEL USING D-OPTIMAL DESIGN

摘要

The experimental design methodology was applied for screening and response surface modeling of adsorption of water vapors from air on a fixed bed of silica gel grains. The variables considered were the air flow rate, temperature, air relative humidity and drying time. The D-optimal design allowed developing a quadratic model as a functional relationship between packed-bed adsorption efficiency and the independent variables. It was found that all factors considered have an important effect in the degradation efficiency of the organic matter.
