AARL ELUTION PROCESS PDF

AARL Carbon Stripping System Operation: Elution & Electrowinning. The time required for pressure stripping is generally from 10 to 14 hours. At the end of the carbon cool stage, water is pumped into the column via valve AV so as to maintain pressure within it and force the barren carbon out of the column via valve AV into the carbon transfer line.
