Patent ID: 8904970

Claim:
A process for the generation of process steam and boiler feed water steam a heatable reforming reactor for the production of syngas, with the process yielding syngas by steam reforming from hydrocarbons and water vapour, the gas being heated by incinerating a fuel gas with an oxygenous gas, and the generated syngas being cooled and then condensed by a series of heat exchangers and a cooling section, so that a dried syngas and a process condensate are obtained, the process also including a conversion of at least part of the obtained carbon monoxide with water vapour to form carbon dioxide and hydrogen, and two different types of steam being made available, which are generated from the evaporation of boiler feed water and the evaporation of process condensate, and the boiler feed water being heated with the syngas by a pre-heater installed downstream of the conversion unit in direction of the gas flow, and the boiler feed water then being evaporated by a steam generator installed upstream of the conversion unit in direction of the gas flow, and the process condensate being heated by a heat exchanger and a pre-heater, both being installed downstream of the conversion unit in direction of the gas flow, wherein the process condensate is evaporated by an additional steam generator installed upstream of the conversion unit.
