Sulphonation plant scrubber wastewater crystallization technology, often utilized in Unit 38 of modern plants (e.g., WEIXIAN), treats caustic soda waste by evaporating moisture to achieve zero liquid discharge. It uses waste heat air (≥100°C) to concentrate, oxidize
to
, and crystallize sodium sulfate, which is then removed.
