WATER INTEGRATION OF DOMESTIC EFFLUENT TREATMENT AND COKER PROCESSING WATER

摘要

A process and system for integrating a domestic effluent treatment operation with a hydrocarbon coking operation. The process and system use domestic effluent water as a source of coker processing water. The process includes retrieving from the domestic effluent treatment operation a domestic effluent water including pathogens. The domestic effluent water is pre-treated to reduce a concentration of pathogens therein, to produce a pre-treated water stream. The pre-treated water stream may be supplied to a coker unit as coker quench water to quench the coker unit and produce a pathogen depleted spent quench water.
