CONTINEOUS GENERATION OF HYDROCARBON GAS/ STEAM MIXTURE AS A CHARGE FOR REFORMING PROCESS TO PRODUCE HYDROGEN OR COMPOSITE GAS AND HEATING IT, AND ERECTED HEAT EXCHANGER

摘要

The invention relates to a process for the continuous generation and preheating of a hydrocarbon gas/steam mixture as the raw material for a reforming process for the production of hydrogen gas or synthesis gas (reformer product). To reduce the treatment cost required for utilising the waste heat arising in the reforming process in connection with the generation and preheating of the hydrocarbon gas/steam mixture, it is proposed that the preheating of the hydrocarbons (6), the generation of the steam and the further heating of the hydrocarbon gas/steam mixture take place in a single heat exchanger, in which the heating medium is separated by partitions from the fluid to be heated (hydrocarbons, water, steam), the water of the steam fraction being injected (7) in the liquid form into the heat exchanger and being conducted directly, with simultaneous at least partial vaporisation, with the stream of the hydrocarbons passed through the heat exchanger. ……
