A process and plant for producing a high purity CO2 product, comprising: providing a CO2-rich stream containing hydrocarbons, hydrogen and/or CO, combining it with a stream rich in methane (CH4), and mixing it with oxygen, thereby forming a CO2/O2- mixture; subjecting the CO2/O2- mixture to a catalytic oxidation step, thereby producing a purified stream having a higher CO2 and/or H2O concentration; removing H2O from said purified stream, for producing said high purity CO2 product stream. The CO2-rich stream is for instance derived from the CO2-removal section of a plant for producing hydrogen.
A process for producing a high purity CO2 product, comprising the steps of:
A plant for producing a high purity CO2 product, said plant comprising:
Use of a CATOX unit for purifying a CO2-rich stream containing hydrocarbons, hydrogen and/or CO, which is derived from a process or plant for producing hydrogen, in particular from a CO2-removal section thereof, while not increasing the carbon emission of the plant.
