A West Coast refinery turned to Evoqua for help in providing a more consistent and reliable quality of purified boiler feedwater. The refinery, using up to 1,500 gpm of demineralized boiler makeup water, was experiencing a variety of problems including aging demineralizers, pending environmental legislation, excessive operation costs, wide variations of raw water quality, and limited capital to address these issues.

Petcoke, a byproduct of petroleum refining, consists largely of carbon and ash residuals from crude oil processing. Depending on the source of the crude, the ash in petcoke will contain low to significant concentrations of nickel, vanadium, iron and other metals. Evoqua Water Technologies was contacted by a California business that accumulates, stores and ships petroleum coke to its customers worldwide.

A Gulf Coast chemical plant was faced with an unreliable demineralizer system to meet a proposed expansion of boiler feedwater requirements. In addition, the plant had a wastewater goal of zero liquid discharge. High total dissolved solids (TDS) in a proposed new well-water source threatened to increase demineralizer regeneration frequency, greatly increasing acid and caustic usage.
