Process for heat utilization in steam reforming, having a high-temperature conversion unit, a first heat exchanger, boiler feed water preheater, product condensate heat exchanger, and low-pressure evaporator, a cooling section, in which the process gas is further cooled and a condensate stream is generated and the resultant process gas is passed through at least one unit for further processing. Wherein a first part of the boiler feed water stream is passed into the low-pressure evaporator, and the low-pressure steam generated is divided and a first substream of the low-pressure steam is conducted into the water treatment unit for heat transfer and a second substream of the low-pressure steam is passed to at least one consumer. A second part of the boiler feed water stream is passed via a heat exchanger and one or more boiler feed water preheaters and finally passed for steam generation. |
