Single Orifice Effervescent Atomizer in simulated Counter–flow Conditions

Popis výsledku v původním jazyce

CO2 is the most severe greenhouse gas released into the atmosphere and is responsible for the global temperature increase. The amount of CO2 released can be reduced through deployment of post-combustion CO2 capture. Spray columns, as simple gas cleaning contractors, utilise different types of atomizers e.g. pressure atomizers, twin fluid atomizers and rotary atomizers. The CO2 capture process requires well-tailored spray characteristics, such as mean drop size, drop size distribution, droplet density, spray cone angle (SCA) and droplet velocity. Effervescent atomizers are beneficial, in that way they can be used for spraying viscose chemical solutions to counterflowing flue gasses. However, they typically create a wide droplet size distribution. Small droplets from this wide distribution are carried away by the ambient flow and cause significant sorbent losses. The total surface area, which determines the rate of mass transfer of CO2, is significantly reduced by this droplet drift. In this study, the
