Abstract
In an aspect, the present disclosure provides a method for the oxidative coupling of methane to generate hydrocarbon compounds containing at least two carbon atoms (C2+ compounds). The method can include mixing a first gas stream comprising methane with a second gas stream comprising oxygen to form a third gas stream comprising methane and oxygen and performing an oxidative coupling of methane (OCM) reaction using the third gas stream to produce a product stream comprising one or more C2+ compounds.
Claims30
A process for production of hydrocarbons, the process comprising the steps of:
- converting at least a feed stream comprising methane (CH4) and oxygen (O2) feed into a conversion effluent by oxidative coupling of methane (OCM);
- directing said conversion effluent to at least one product retrieval stage to produce one or more product streams and a remaining conversion effluent;
- directing at least a portion of said remaining conversion effluent to a hydrogenation stage to produce a hydrogenation effluent, and directing said hydrogenation effluent to a methanation stage to produce a recycle stream;
- and
- adding at least part of said recycle stream to said feed stream.
A method for producing hydrocarbon compounds, comprising:
- (a) directing a feed stream comprising methane (CH4) and an oxidizing agent into an oxidative coupling of methane (OCM) unit to generate from at least a portion of said CH4 and said oxidizing agent an OCM effluent comprising said hydrocarbon compounds;
- (b) recovering a portion of said OCM effluent in one or more product streams;
- (c) directing an additional portion of said OCM effluent into a recycle loop that comprises (i) a hydrogenation unit that hydrogenates at least a portion of unsaturated hydrocarbons from said additional portion of said OCM effluent, and (ii) a methanation unit that reacts hydrogen (H2) with carbon monoxide (CO) or carbon dioxide (CO2) from said additional portion of said OCM effluent in a methanation reaction to form CH4, wherein said recycle loop outputs a recycle stream comprising said CH4 generated by said methanation unit;
- and
- (d) directing at least a portion of said recycle stream into said OCM unit.
