Abstract
The present application relates to a production plant comprising—a synthesis gas generation step (1) arranged to receive a hydrocarbon or carboneous feedstock (2) and in a synthesis gas generation process provide a syngas, —a production step (4) arranged to receive the syngas and produce a product stream (5), —a reverse water gas shift step (4) arranged to receive a H2 rich gas stream (7) and a C02 feed (8) and in a RWGS step obtain a reverse shifted gas stream (9), and—means (10) for adding said reverse shifted gas stream (9) to the synthesis gas stream (3).
Claims18
Production plant comprising
- a synthesis gas generation step arranged to receive a hydrocarbon or carboneous feed stock and in a synthesis gas generation process provide a syngas
- a production step arranged to receive the syngas and produce a product stream
- a reverse water gas shift step arranged to receive a H2 rich gas stream and a CO2 feed and in a RWGS step obtain a reverse shifted gas stream, and
- means for adding said reverse shifted gas stream to the synthesis gas stream.
A process for adjusting the CO/CO2 ratio in a synthesis gas, said process comprising
- in a Methanol loop producing a Methanol stream from a synthesis gas
- in a RWGS loop producing in a RWGS step a shifted gas stream at least from a CO2 feed and a H2 rich gas stream, and
- adding the produced shifted gas stream to the syngas upstream the Methanol loop.
