Treatment of spent merox caustic waste in industrial ecology frames

Abstract

Possible treatment options of spent Merox caustic waste have been explored for the sake of recommending a neutralization scheme that is not only affordable but promises modest profit and provides an environmentally benign technique that meets criteria of industrial ecology. We concluded to recommend a system in which two waste streams are co-processed and in addition to efficient neutralization the potential of a renewable energy resource is also produced. Colloid chemical specifics of the waste in question have been shown to have influence on processing this hazardous and otherwise difficult to treat waste of petroleum refining.
