Abstract:
1. A method for producing a synthesis-gas product gas and at least one product vapor stream, the method comprising: catalytic steam reforming a hydrocarbonaceous feedstock in a steam reformer with variable production capacity of the synthesis-gas product gas so as to form the synthesis-gas product gas and the at least one product vapor stream, the steam reformer including a plurality of catalyst-containing reformer tubes and a reformer furnace with burners for firing the reformer tubes; cooling the hot synthesis-gas product gas stream in at least one heat exchanger by indirect heat exchange against a stream of water so as to form a cooled synthesis-gas product gas stream and a first partial vapor stream; and supplying the first partial vapor stream to the product vapor stream, wherein the reforming furnace is operated so as to include the following steps:
