SO2 Scrubbing Spray Nozzles

Custom Solutions Bulletin 027
Application #051195
Industry: Chemical Processing
Application: SO2 Scrubbing
Product Description: Special High Flow NCK


A BETE customer from a large international chemical company called BETE Applications Engineering with the requirement for nozzles to go into a scrubber they were preparing to build. The scrubber service would be removing sulfur dioxide from a gas by reaction with sodium hydroxide that would be injected by the nozzles. Sodium sulfite and water would result. The nozzle would be required to flow 1150 gpm (4350 L/min) at 30 psi (2.1 bar) and unleash substantial energy to facilitate mixing.


BETE Applications Engineering coordinated efforts with both the chemical company and the engineering firm that was contracted to build the scrubber. The nozzle specified for the job was a special high flowing NCK in Teflon with a 15 degree spray angle. The narrow spray angle was chosen to concentrate the force.
