Recycle loop in production of hydrocarbons by OCM

In the present application is described a plant and process for production of hydrocarbons, the process comprising the steps of: - converting at least a feed stream comprising CH4 and O2 feed into a conversion effluent by oxidative coupling of methane (OCM), - withdrawing one or more product streams from the conversion effluent by at least one product retrieval stage; - recycling at least a portion of the remaining conversion effluent as a recycle stream in a recycle loop, said recycle loop comprising a hydrogenation stage and a methanation stage; and - adding at least part of the recycle stream to the feed stream.
