    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.

  • Patent number: 10189723
    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.
