Abstract
Integrated systems are provided for the production of higher hydrocarbon compositions, for example liquid hydrocarbon compositions, from methane using an oxidative coupling of methane system to convert methane to ethylene, followed by conversion of ethylene to selectable higher hydrocarbon products. Integrated systems and processes are provided that process methane through to these higher hydrocarbon products.
Claims17
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 C3 to C10 hydrocarbons in separate streams;
- (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 C2 to C4 compounds and (ii) a heavy product stream comprising C4 to C10 compounds;
- (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 C2 to C4 compounds from said light product stream to produce additional said first higher carbon products or second higher carbon products, or (ii) controlling a temperature in said first ethylene conversion reactor or in said second ethylene conversion reactor.
