ABSTRACT:
Selenium and other non-volatile inorganic contaminants in refinery waste water are removed from said waste water and disposed of by a process comprising subjecting the contaminated waste water stream to a non-chemical concentration process producing a contaminants concentrate stream and a clean water stream and passing the contaminants concentrate stream to a coker unit wherein it is used as coker elutriant to quench the coke.
