Study on effective phase interfacial area at different injection angles of hydro-jet cyclone

In contrast to conventional tower-type mass transfer equipment, the hydro-jet cyclone exhibits superior mass transfer capabilities. This study presents a novel investigation into the effective phase interfacial area (ae) of the hydro-jet cyclones across five unique injection angles. The investigation employs a combination of CFD simulations and experimental analysis utilizing a CO2-NaOH system. The results indicate that the 45 degrees upward incidence angle yields the most favorable flow field characteristics for efficient mass transfer when liquid-gas ratio ranges from 0.18 to 0.27. The ae values of the hydro-jet cyclones range from 1846 to 5358 m2 & sdot;m- 3, representing an approximate fivefold increase compared to the rotating packed tower. Empirical formulas for ae are proposed for both vertical incidence and upward 45 degrees incidence angles. This significant enhancement in ae offers the advantage of reducing the equipment volume of the hydro-jet cyclone, leading to substantial cost savings in terms of investment and auxiliary devices.
