AI Overview
Sulphonation plant alkali wastewater evaporation and crystallization, often utilizing Unit 38 Technology, treats scrubber waste by oxidizing
and
, then evaporating water to produce solid
(sodium sulfate) hydrate crystals. This process achieves zero wastewater discharge (ZLD), with some systems utilizing waste heat from converters to drive evaporation, enhancing efficiency.
