Water Management

Impact of opportunity crudes on refinery desalter and wastewater treatment performance—Part 1
Headworks Intl.: Basu, S.

Refiners are becoming increasingly dependent on opportunity crudes to stay competitive and enhance margins in the industry’s present uncertain state.

Options for meeting wastewater effluent selenium limits
Brown and Caldwell: Gerhardt, M.  |  Steinwinder, T.

Wastewater treatment units (WWTUs) in petroleum refineries are designed to meet effluent limitations incorporated into National Pollutant Discharge Elimination System (NPDES) permits for “conventional pollutants.”
