Carbon regeneration - Outotec
The stripped carbon will retrain significant quantity of organic and inorganic contaminants (foulants) present in the cyanide slurry. Prior to returning the barren carbon to the process, it is necessary to regenerate the carbon by removing these contaminants (foulants). Additional step, Carbon is not selective.

Sour Water Stripper Process | Yokogawa America
Sour Water is the wastewater that is produced from atmospheric and vacuum crude columns at refineries. Hydrogen sulfide and ammonia are typical components in sour water that need to be removed before the water can be reused elsewhere in the plant. Removal of these components is done by sending the sour water from the process to a stripping tower where heat, in the form of steam, is applied ...
