ORGANIC VAPOR RECOVERY USING ACTIVATED CARBON FIBER CLOTH ELECTROTHERMAL-SWING ADSORPTION

抄録

There were 10⁹ kg of hazardous chemicals emitted to the atmosphere from United States during 2000. Reduction in these emissions can occur by capture and recovery of these chemicals with an electrothermal-swing adsorption system using activated carbon fiber cloth (ACFC). This system treated an air stream containing 73 ppmv to 1, 006 ppmv methyl ethyl ketone at 1.7 sm³/min. Throughput ratio, length of unused bed, equilibrium adsorption capacity, removal and liquid recovery efficiencies, and energy efficiency were used to characterize the system.
