Abstract (en)

[origin: CA2743089A1] Process for heat utilization in steam reforming, comprising a high-temperature conversion unit, a first heat exchanger, and hereinafter 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. In addition, a deionized water stream, a water treatment unit, 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. The condensate stream from the cooling section is passed into the product condensate heat exchanger via a unit for pressure elevation.
