ABSTRACT:
Excess alcohol, e.g. methanol contained in a C.sub.4 -C.sub.6 hydrocarbon stream is removed in process using less water and energy than a conventional water wash by subjecting the stream to a first single stage water wash with 2 to 10 wt % water based on the hydrocarbon where most of the alcohol is removed and then washing the raffinate having reduced methanol therefrom subjected to multistage water wash to remove the remainder of the alcohol.
