... Abstract Dimethyl ether (DME) is a small, slightly polar component, non-toxic that exhibits nearly ideal behavior with known liquid-state hydrocarbons, and is partially miscible with water/brine. In a multicomponent brine/DME/oil system, it partitions preferentially into the hydrocarbon phase...
