In the sulfonation process, SO3 is reacted with aromatic hydrocarbon. The SO3 in the feed will combine with moisture in the air creating acid, which can cause safety and corrosion problems. In addition to this, the acid mist in the SO3 feed can create a hazy appearance in the final product.
Before reaction step
FLEXIFIBER® mist eliminators can help improve product quality by removing contaminants in the SO3 stream prior to the reaction.
After reaction step
FLEXIFIBER® mist eliminators remove acid mist after the reaction to eliminate discharge of acid to the atmosphere.
