Operational challenges in sour water stripping
Operational challenges in sour water stripping

Sour water ,stripping, is considered ‘fouling service’ and thus it is generally recommended that fouling-resistant trays be installed in the column. In some instances, improved run time has been achieved by replacing conventional trays with fouling-resistant trays1 and installing bypasses around individual feed/effluent exchangers (there are often several in series) to allow for on-stream ...
