Enhancement of water use efficiency at plants processing hydrocarbon materials

A method is proposed for multicriteria performance assessment of water supply and disposal systems. Approaches are proposed for improving the utilization efficiency of water resources in plants processing hydrocarbon materials based on the potential of main-production technological processes and in-plant systems of heat and water supply, as well as industrial waste utilization. Engineering solutions are given for involving regenerated wastewater in the production cycle and reducing water consumption from external natural sources, and their system efficiency is evaluated.
