11. Reformer tubes normally used in the refining, petrochemical and fertilizer industries are manufactured by the centrifugal casting process and heat-resistant austenitic alloys such as HK -40, HP-40, and HP -Niobium modified materials. A design life of 100, 000 operating hours has been the normal time-based criteria for considering retirement of tubes.
Primary reforming
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.
