Abstract: Systems and methods for treating a stream (12) from a chemical enhanced oil recovery (CEOR) process are disclosed. The method includes contacting the feed stream (12) with a plurality of media composite particles (20) to remove hydrocarbons from the feed stream (12); and generating a treated stream (40) comprising a reduced amount of the hydrocarbons and at least a majority of the viscosity-enhancing polymer remaining therein relative to the feed stream (12). The feed stream (12) includes the hydrocarbons, a concentration of a viscosity-enhancing polymer of at least about 10 mg/L, and an aqueous fluid. The media composite particles (20) each comprise a mixture of a cellulose-based material and a polymer.

Abstract: According to various aspects and embodiments, a system and method for treating a feed stream comprising hydrocarbons, suspended solids, and an aqueous-based liquid is provided. The systems and methods may utilize a stratified multi-media bed that includes at least one layer of a composite media comprising a mixture of a cellulose-based material and a polymer. According to certain aspects, contacting the feed stream with the stratified multi-media bed comprises coalescing and filtering the feed stream. According to at least one aspect, the systems and methods include a draft tube positioned within the stratified multi-media bed that may be utilized for backwashing the layers of filter media.

In certain systems and methods, the media composite is capable of being backwashed. The stream comprising the hydrocarbons and aqueous-based liquid may be separated by contacting the stream with the media composite. In certain system and methods, the stream comprising the hydrocarbons and aqueous-based liquid may be coalesced by contacting the stream with the media composite.
