What is proposed is a process and a plant for parallel production of methanol and ammonia by heterogeneously catalyzed reaction of hydrogen and carbon oxides on the one hand and hydrogen and nitrogen on the other hand. This includes producing a raw synthesis gas stream and dividing it into two portions. A first raw synthesis gas substream is used as input for a methanol synthesis to obtain raw methanol and a methanol synthesis purge stream. A second raw synthesis gas substream is subjected to a CO conversion, a carbon dioxide separation and a liquid nitrogen scrubbing and then sent to an ammonia synthesis. According to the invention at least a portion of the methanol synthesis purge stream is sent to the ammonia synthesis and at least one substream obtained from the second raw synthesis gas substream is passed to the methanol synthesis.

A plant, such as a hydrocarbon plant, is provided, which consists of a syngas stage for syngas generation and a synthesis stage where said syngas is synthesized to produce syngas derived product, such as hydrocarbon product. The plant makes effective use of various streams; in particular CO.sub.2 and H.sub.2. The plant does not comprise an external feed of hydrocarbons. A method for producing a product stream, such as a hydrocarbon product stream is also provided.

A hydrogen composition having a recycle content value is obtained by processing a recycle content feedstock to make a recycle content hydrogen or by deducting from a recycle inventory a recycle content value applied to a hydrogen composition. At least a portion of the recycle content value in the feedstock or in an allotment obtained by a hydrogen manufacturer has its origin in recycled waste plastics.

A novel process for synthesis gas generation comprises treating a hydrocarbon feed in a primary reformer (PR), compressing at least part of the flue gas from the primary reformer in a compressor (C1), and feeding the compressed flue gas to a secondary reformer (SR) together with the primary reformer effluent. In the process, enriched air (EA) is added either to the primary reformer, to the secondary reformer or both. The process is especially suited for co-production of ammonia and methanol or for production of either ammonia or methanol. The total CO.sub.2 emission is lowered considerably by using the process of the invention.
