The experimental setup was designed to study the effect of natural charging of dropletsduring spraying (called spray electrification orspray charging) in a wet scrubber. The influenceof nozzle material, liquid feed rate, and liquidcomposition on the specific charge (charge per unit volume of liquid) formed in spraying was measured. It was found that the nozzle material hasno measurable effect on this specific charge. Increasing the liquid feed rate increases the specific charge significantly. Increasing solute (NaCl or NaOH) concentration increases the conductivity that decreases the formed specific charge. The same correlation between the specific chargeand conductivity was also observed with real scrubbing liquids. It is proposed that the specificcharge depends only on the value of liquid conductivity, not on liquid composition. The conductivity of the tested scrubbing liquids was high enough to suppress the formation of a high specific charge during spraying.
