摘要

An automated bench-scale adsorption device was designed and used to study effects of select independent engineering parameters on the ability of the system to capture and recover a hazardous air pollutant (HAP, I.e. methyl ethyl ketone) from air streams. Experiments were completed in two stages: Stage I consisted of “Screening Experiments” and Stage II consisted of “Central Composite Design experiments.” The screening experiments were used to identify significant factors. Response surfaces for the significant factors were then determined during the second stage of the experiments. These experimental results provided a better understanding of the physical phenomena and evaluation of significant factors that influence the ability of the adsorption system to capture and recover methyl ethyl ketone from air streams. This system can be modified to minimize the energy consumption per unit mass of liquid recovered by choosing an appropriate adsorbent, number of cartridges per vessel, packing density of the adsorbent, and regeneration temperature of the adsorbent. These results were also used to scale-up this novel technology.
