Abstract
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 CO2 and H2. 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.
Claims20
A plant, said plant comprising:
- a. a syngas stage, said syngas stage comprising a methanation section and/or a reverse water gas shift (rWGS) section, and an autothermal reforming (ATR) section;
- and
- b. a synthesis stage,
- said plant further comprising:
- a first feed comprising hydrogen to the syngas stage;
- a second feed comprising carbon dioxide to the syngas stage;
- and
- a third feed comprising oxygen to the ATR section,
- wherein said syngas stage is arranged to provide a syngas stream and feed said syngas stream to the synthesis stage, and
- wherein the plant does not comprise an external feed of hydrocarbons,
- wherein the syngas stage comprises a methanation section and/or a reverse water gas shift (rWGS) section, arranged upstream the autothermal reforming (ATR) section,
- wherein the synthesis stage is arranged to convert said syngas stream into at least a product stream and a hydrocarbon-containing off-gas stream, and
- wherein at least a portion of said hydrocarbon-containing off-gas stream or at least a portion of said product stream is fed to the syngas stage as a fourth feed comprising hydrocarbons, upstream of said ATR section and between said methanation section and/or said reverse water gas shift (rWGS) section and said ATR section.
