Abstract
A system is described for providing a hydrocarbon product stream. An electrolysis section provides a syngas stream from a first feed comprising CO2 and a second feed comprising H2O, which is then passed to an F-T section where it is converted to a hydrocarbon product stream and a tail gas stream. An electrical steam reformer section said tail gas stream and convert it to a second syngas stream, which is then recycled upstream the FT section. A process is also provided for converting a first feed comprising CO2 and a second feed comprising H2O to a first hydrocarbon product stream in a system according to the invention. The system of the invention can be combined with an upgrading section, in a gas-to-liquid plant.
Claims20
A system for providing a first hydrocarbon product stream, said system comprising:
- a Fischer-Tropsch (F-T) section,
- an electrolysis section arranged upstream said F-T section,
- a first feed comprising CO2 to the electrolysis section,
- a second feed comprising H2O to the electrolysis section, and
- a first electrical steam reformer section,
- wherein
- said electrolysis section is arranged to provide a first syngas stream from said first and said second feeds by electrolysis,
- said F-T section is arranged to receive at least a first portion of said first syngas stream and convert the first portion to a first hydrocarbon product stream and a tail gas stream,
- optionally, said first electrical steam reformer section is arranged to receive at least a second portion of said first syngas stream and convert the second portion to a second syngas stream,
- said first electrical steam reformer section is arranged to receive at least a first portion of said tail gas stream and convert the first portion to a second syngas stream, and
- said second syngas stream is arranged to be fed to the F-T section.
