NOVELTY - Integrating power generation and steam methane reformer (SMR), involves introducing compressed air stream (103) and combustor feed gas stream (107) into combustor (109), to produce exhaust gas stream (110); introducing this stream into shell-side of an SMR (113), to provide heat for reforming reaction, and generating syngas stream (119) and second exhaust gas stream (114); introducing second exhaust stream and secondary fuel stream (122) into second combustor (115), to produce third exhaust gas stream (116); introducing it into an expander (117), to produce power.    USE - For integrating power generation and an SMR (Claimed).    ADVANTAGE - This cogeneration scheme improves overall thermal efficiency of the process. It reduces the amount of by-product steam. The hydrogen generation is done in an exchanger type of reactor that is much more compact as compared to a conventional SMR furnace. The use of heat for hydrogen production improves the efficiency of power generation and hydrogen generation. This processing scheme differs from the prior art in a number of respects. First the instant process uses higher level heat, upstream of expander for reforming. Second the hot gases that are used in the reforming exchanger are at high pressure, thereby reducing the size of the reforming exchanger. Third the proposed process recovers hydrogen from the reformed gas mixture. Fourth the proposed process removes hydrogen from the gas mixture at elevated temperature, thereby allowing the use of hot residue gas fuel.    DETAILED DESCRIPTION - Integrating power generation and an SMR, involves introducing combustion air stream (101) into a compressor (102), to produce compressed air stream (103); introducing this stream and combustor feed gas stream (107) into a combustor (109), to produce first exhaust gas stream (110); followed by either Method A: introducing first exhaust gas stream (110) into shell-side of an SMR (113), to provide heat for the reforming reaction, and generating syngas stream (119) and a second exhaust gas stream (114), introducing second exhaust gas stream and secondary fuel stream (122) into a second combustor (115), to produce a third exhaust gas stream (116); introducing third exhaust gas stream into an expander (117), to produce power and fourth exhaust gas stream (118); or Method B: introducing (S1) into an expander, to produce power output and a second exhaust gas stream; introducing the second exhaust gas stream into the shell-side of an SMR, to provide heat for the reforming reaction, and generating a syngas stream and a third exhaust gas stream or Method C: introducing (S1) into a first expander, to produce power output and a second exhaust gas stream; blending the second exhaust gas stream with an expanded secondary fuel gas stream and introducing the blended gas stream into a second combustor, to producing a third exhaust gas stream; introducing the third exhaust gas stream into the shell-side of an SMR, to provide heat for the reforming reaction, and generating a syngas stream and a fourth exhaust gas stream.
