Abstract
Process and plant for producing a synthesis gas by catalytic steam reforming of a hydrocarbon feedstock in a steam reforming unit, wherein water is removed from the synthesis gas as a process condensate, wherein boiler feed water is introduced in the process, and wherein said process or plant produces at least two separate steam streams: a pure steam which is generated from at least a portion of said boiler feed water by the cooling of synthesis gas, and a process steam which is generated by evaporating at least a portion of the process condensate by using synthesis gas, optionally together with pure steam and/or flue gas from the steam reforming unit.
Claims13
A process for producing a synthesis gas by catalytic steam reforming of a hydrocarbon feedstock in a steam reforming unit, said steam reforming unit optionally generating a flue gas, wherein water is removed from the synthesis gas as a process condensate, wherein boiler feed water is introduced in the process,
- said process comprising producing at least two separate steam streams:
- i) a pure steam stream which is generated from at least a portion of said boiler feed water (BFW) by the cooling of the synthesis gas;
- and
- ii) a process steam stream which is generated by evaporating at least a portion of the process condensate by the cooling of the synthesis gas,
- wherein the process steam stream is generated in a process condensate boiler (PC-boiler),
- wherein generating the process steam stream also comprises the cooling of at least a portion of said pure steam stream.
