Abstract
Systems and methods for treating a stream comprising a hydrocarbon liquid and an aqueous-based liquid are provided. The systems and methods may utilize a media composite comprising a mixture of a cellulose-based material and a polymer. In certain systems and methods, the media composite is capable of being backwashed. The stream comprising the hydrocarbon liquid and aqueous-based liquid may be separated by contacting the stream with the media composite. In certain system and methods, the stream comprising the hydrocarbon liquid and aqueous-based liquid may be coalesced by contacting the stream with the media composite.
Claims36
A method for treating a feed stream comprising a hydrocarbon liquid and an aqueous-based liquid, comprising:
- introducing the feed stream to an inlet of a vessel containing a media composite, the media composite comprising a mixture of a cellulose-based material and a polymer;
- and
- contacting the feed stream with the media composite to produce a treated stream, the treated stream comprises a predetermined target concentration of the hydrocarbon liquid.
A method for treating a feed stream comprising a hydrocarbon liquid and an aqueous-based liquid, comprising:
- passing the feed stream at a first flux rate through a coalescer containing a media composite, the media composite comprising a mixture of a cellulose-based material and a polymer to produce a coalesced stream;
- and
- passing the coalesced stream at a second flux rate through a filter device in communication with the coalescer and containing the media composite to produce an effluent stream.
The method of claim 21, further comprising backwashing the filter device based on the at least one measured property of the effluent stream to produce a hydrocarbon liquid effluent.
A method for treating a feed stream comprising a hydrocarbon liquid and an aqueous-based liquid, comprising:
- passing the feed stream through a coalescer containing a media composite comprising a mixture of a cellulose-based material and a polymer to produce a coalesced stream, the coalesced stream comprising a reduced concentration of an emulsified hydrocarbon liquid relative to the feed stream;
- and
- separating the coalesced stream by passing the coalesced stream through a separator device to provide at least one of a hydrocarbon liquid stream and an aqueous stream.
A system for treating a feed stream comprising a hydrocarbon liquid and an aqueous-based liquid, comprising:
- at least one coalescer in communication with the feed stream and containing a media composite comprising a mixture of a cellulose-based material and a polymer;
- and
- at least one separator device in communication with the coalescer.
A method of facilitating a treatment system for separating a hydrocarbon liquid and an aqueous-based liquid from a feed stream, the treatment system comprising at least one vessel in communication with the feed stream, the method comprising:
- providing a media composite comprising a mixture of a cellulose-based material and a polymer, and positioned in the vessel to be contacted with the feed stream.
