Hi there
We are having trouble with a caustic scrubber recirculation pump that keeps getting gummed up with fine precipitate behind the impellor, causing failure & plant shutdown.
The pump is from a reputable supplier, who has not seen the problem before, despite having supplied several units for hypo/caustic scrubbing.
The scrubber operates at a pH above 10 treating around 200 ppm H2S with blowdown occurring at about 10% sump volume.
Discharge is clear to milky colour.
We would really like to hear from anyone operating a caustic scrubber as to what pumps are used & supplier etc
Any assistance is appreciated.
Regards
