WebJan 1, 2002 · A number of kraft pulp mills currently steam strip foul condensates and burn the stripper off-gases (SOGs) in thermal oxidizers, lime kilns, or boilers to destroy odorous total reduced sulfur (TRS) compounds and volatile organics. We expect additional kraft mills will install steam strippers to comply with the MACT portion of the Cluster Rule. WebNov 9, 2015 · 2 in the gas; these designs take advantage of the fact that the absorption of CO 2 in caustic is significantly slower than that of H 2S. Other designs are available to treat sour water stripper off gas at the refinery by caustic scrubbing the H 2S followed by steam stripping the NH 3 absorbed in the spent caustic product. Caustic scrubbers have ...
