摘要： A light olefin feed for an olefin utilization process is subjected to a water wash to remove water-soluble contaminants after which the water is separated from the olefin by coalescence separation at a low temperature, typically below 40° C. The coalescence separation technique is effective for separating the olefins from the water with its dissolved contaminants. If desired, a supplemental washing may be carried out by adding additional water to the feed/water mix after the initial wash step but before the coalescer in order to remove provide additional contaminant removal.
