Abstract:
A method has been discovered for stripping aromatic hydrocarbon contaminants from wastewater and retaining the aromatic hydrocarbons on activated carbon. The wastewater is contacted countercurrently with stripping gas. The stripping gas is passed over a bed of activated carbon to regenerate the stripping gas. The entire volume of stripping gas is recycled to the stripping vessel. There is no purge of stripping gas or aromatic hydrocarbons to the atmosphere. The removed aromatic hydrocarbons are retained by the activated carbon and periodically recovered. An activated carbon particularly adapted for retaining and recovering aromatic hydrocarbons has been found.
