    Abstract: A process for the conversion of carbon monoxide and hydrogen to ethylene, said process comprising the following steps:
    i) introducing carbon monoxide, hydrogen and methyl acetate into an alcohol synthesis unit to produce a first product stream comprising methanol and ethanol;
    ii) separating a methanol and ethanol rich stream and a carbon monoxide and hydrogen rich stream from the first product stream;
    iii) introducing at least part of the methanol and ethanol rich stream into a dehydration reactor to produce a second product stream comprising ethylene and dimethyl ether;
    iv) separating an ethylene product stream and a dimethyl ether product stream from the second product stream; and
    v) introducing carbon monoxide, hydrogen and at least part of the dimethyl ether product stream into a carbonylation reactor to produce a third product stream comprising methyl acetate;
    wherein at least a part of the methyl acetate introduced into the alcohol synthesis unit in step i) is recycled from the third product stream produced from the carbonylation reactor in step v); and
    wherein the alcohol synthesis unit of step i) comprises a catalyst which is effective to perform hydrogenolysis of methyl acetate and a catalyst which is effective to produce methanol from carbon monoxide and hydrogen, preferably in the form of synthesis gas; and
    wherein the carbonylation reactor of step v) comprises a zeolite catalyst effective for said carbonylation reaction.

    Abstract: A process for removing water from an ethylene stream comprising water, said process comprising: introducing an ethylene stream comprising water into, and circulating said ethylene stream through, a separation vessel; - introducing a liquid diethyl ether stream into, and circulating said liquid diethyl ether stream through, the separation vessel, so that said liquid diethyl ether stream and said ethylene stream comprising water are brought into contact; recovering an ethylene stream having a reduced water content from the separation vessel; and optionally - recovering a liquid diethyl ether stream having an increased water content from the separation vessel.
