Claim:
1. A method for producing fuel from ethylene produced by oxidative coupling of methane (OCM), the method comprising: (a) providing an OCM product gas comprising ethylene from an OCM process; (b) directing a first portion of said OCM product gas into a first ethylene conversion reactor and directing a second portion of said OCM product gas into a second ethylene conversion reactor in parallel to said first ethylene conversion reactor, said first ethylene conversion reactor and said second ethylene conversion reactor operated under different reactor conditions; (c) in said first ethylene conversion reactor and in said second ethylene conversion reactor, reacting said ethylene from said OCM product gas to produce first higher carbon products and second higher carbon products different from said first higher carbon products, said first higher carbon products and said second higher carbon products including C (d) combining said separate streams into a product stream, and cooling said product stream in a heat exchanger; (e) directing said product stream from said heat exchanger into a flash drum that condenses said product stream to produce (i) a light product stream comprising C (f) directing said light product stream to a compressor that compresses said light product stream; and (g) directing said light product stream from said compressor to said first ethylene conversion reactor or said second ethylene conversion reactor, thereby (i) reacting at least a portion of said C
