Hydrogen generation reformer
The hydrocarbon steam reforming process is the principal industrial process used to manufacture synthesis gas for the production of ammonia, hydrogen and methanol. The heart of this process is the tubular primary reformer where the hydrocarbon feed plus steam is catalytically reacted to produce the synthesis gas. The standard primary reformer system is the tubular reformer where the feed stream passes over the catalyst packed in multiple banks of externally heated tubes. The tubes are heated in a refractory lined firebox which may be top, side, or bottom fired. The feed flow can be down flow or up flow through the tubes. With improvements in tube metallurgy, primary reformers operate at pressure up to 60 bar and tube wall temperatures up to 1000° C. The average heat flux may be as high as 30, 000 BTU/hr. Ft2. The feedstock may vary as natural gas, LPG, or naphtha.
