Analysis of VOC Reversing Adsorption and Desorption Characteristics for Actual Effeciency Prediction for Ceramic Honeycomb Adsorbent.

Excellent toluene removal via adsorption by honeycomb adsorbents under high temperature and humidity conditions

“…The use of an adsorption tower filled with granular adsorbents is a typical adsorption method [5]. However, large pressure losses occur in fixed adsorption towers filled with granular adsorbents, and therefore a separate pressurizing device is required to process exhaust gases [6]. In recent years, rotary adsorption systems that can adsorb and regenerate VOCs while reducing pressure load through the use of a honeycomb-like structure coated with adsorbent materials has been widely applied, and studies on such systems are being actively conducted [7][8][9].…”

Optimizing operating parameters of a honeycomb zeolite rotor concentrator for processing TFT-LCD volatile organic compounds with competitive adsorption characteristics

“…The removal efficiency of an HZRC is influenced by parameters such as the process flow rate, rotation speed, thermal response, and the type of zeolite used to coat the concentrator [5][6][7]. Several studies have estimated the non-dimensional number between the efficiency and optimal rotation speed of the rotor, with a specific set of operating and design parameters [8,9].…”

“…Those results provided information for field applications to semiconductor industries to obtain optimal operating conditions of the concentrator for both efficient VOC controls and energy savings. Both field scale [3,10,[13][14][15] and lab-based assessments [2,7,8,12] have been performed for such an HZRC system, and this system can achieve 90% VOCs removal efficiency over a long period of stable operation. However, the current field efficiencies of HZRCs applied to thin film transistor liquid crystal display (TFT-LCD) industries are not as efficient as those used in the semiconductor and other chemical industries.…”

The Volatile Organic Compound (VOC) Removal Performance of Desiccant-Based Dehumidification Systems: Testing at Sub-ppm VOC Concentrations

“…Mitsuma et al investigated VOC removals for such applications. They tested both the desiccant material in a fixed bed configuration (Mitsuma et al 1998a) and using an actual desiccant wheel (Mitsuma 1998b). They examined the removal of butyl acetate at concentrations of approximately 360 ppm and a variety of experimental conditions.…”
