COMPONENTS FOR STEAM REFORMER

There are several types of conventional Primary Reformer Furnace designs used throughout the petrochemical industry. The Furnace, could rightly been stated, is at the “heart” of every Syngas process plant and forms an integral part of it. In all cases, the Reformer Radiant Section contains several hundred vertically oriented straight centrifugally cast tubes, commonly known as Reformer- or Catalyst-Tubes in which reactant gases at 450 – 650 º and 30 to 45 bar(g) arrive through an Inlet Manifold, are distributed to the Reformer Tubes filled with catalyst, heated to 800 - 900º C, and then collected and delivered to the next stage of the process. The tube metal temperature will be in the range of 875 - 975ºC, typically.

Experience shows that Reformer Tube Assemblies, produced by centrifugal casting in heat-resistant materials, are in the very best position to withstand the ever increasing rigorous operational conditions. S+C has been incorporating the latest improvements and innovations in the design of new tube materials. This improved alloy, our Centralloy® G 4852 Micro R material has been introduced and put into service in several operating plants in 2005, already. Since then S+C supplied Reformer Tubes in Centralloy® G 4852 Micro R material for many major projects around the world, with the thinnest tube wall possible and it is understood that tube life is expected to last longer and perform more reliable under adverse conditions such as a high number of start-up / shut-downs, overheating, hot spots due to catalyst performance etc. etc
