TREATMENT METHOD AND PLANT FOR PETROLEUM REFINERY PROCESS EFFLUENTS

摘要

A treatment method for petroleum refinery process effluents includes the steps of mechanical filtration of effluent from SWS, adsorption of the organic substances present in the effluent and potentially harmful for technologies applied in subsequent steps, and total demineralization of the effluent, including decationization with at least one ion exchange resin, subsequent decarbonation step, and deanionization with at least two ion exchange resins, of which one is weak and one is strong.
