SYSTEM AND METHOD FOR TREATING HYDROCARBON-CONTAINING FEED STREAMS

A water processing system includes a pretreatment system disposed within the water processing system. The pretreatment system may treat a feed stream including oil and brine and to generate a first brine stream. The pretreatment system includes a first filtration system that may receive the feed stream, the first filtration system may separate the feed stream into a hydrocarbon stream and an intermediate brine stream, the intermediate brine stream includes a plurality of minerals, and the hydrocarbon stream includes water, the oil, and suspended solids. The water processing system also includes a mineral removal system fluidly coupled to and disposed downstream from the first filtration system. The mineral removal system may receive and remove the plurality of minerals from the first brine stream output from the pretreatment system. The mineral removal system includes a first mineral removal unit that may remove a first portion of the plurality of minerals from the first brine stream and to generate a second brine stream. The water processing system also includes a hydrocarbon removal system disposed within the pretreatment system and fluidly coupled to the first filtration system. The hydrocarbon removal system may receive the hydrocarbon stream, to recover the oil, and to generate a recovered oil stream.
