Disclosed are methods and systems for removing acetone from olefin-containing hydrocarbon streams. In one embodiment, a method for removing acetone from a hydrocarbon stream includes mixing an olefin-containing hydrocarbon stream and a wash water stream to form a mixed olefin/wash water stream, wherein the olefin-containing hydrocarbon stream comprises acetone impurities, and wherein mixing comprises dissolving at least a portion of the acetone impurities in to the wash water stream, coalescing the mixed olefin/water stream to separate the wash water stream with acetone dissolved therein from the hydrocarbon stream, wherein the separated hydrocarbon stream comprises non-coalesced wash water and acetone, and drying the separated hydrocarbon stream to remove at least a portion of the non-coalesced wash water and acetone therefrom and to form a dried hydrocarbon product stream. |
