SO2 Scrubbing Spray Nozzles

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

Situation:

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.

Solution:

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.
