A method for generating hydrogen and/or syngas in a production facility where little or no export steam is produced. Most or all of the steam produced from the waste heat from the process is used in the steam-hydrocarbon reformer. Reformed gas is passed to a pressure swing adsorption system for H₂ purification. In the method, CO₂ is removed from the pressure swing adsorber residual gas prior to recycling the residual gas to the reformer for use as feed and as fuel. Plant efficiencies using the method and prior art-type methods are compared.

The shape (vertically symmetric) of a flow guide 5A according to a conventional technology was modified into the shape (vertically asymmetric) of a flow guide 5 such that the length of a downstream flow guide portion 5d is greater than that of a upstream flow guide portion 5u. Numerical analyses were performed to find the optimum flow guide occupation ratio of the conventional technology and the corresponding total pressure loss coefficient. The obtained values were used as reference values. Further, the flow guide occupation ratio of the upstream flow guide portion 5u was set at 0.4 and the flow guide occupation ratio of the downstream flow guide portion 5d was set at 0.7; at values where the total pressure loss coefficient becomes lower than the reference value. The rectification effect of the flow guide can thus be enhanced.
