Solutions for Steam Crackers
Our products - tailor-made for your specific requirements
The formation of coke in a typical Steam Cracker environment is an inevitable and complex phenomenon. Because of the pyrolysis reaction, thermally insulating hydrocarbon is deposited on the tube walls, so reducing the effective cross-sectional area. To ensure a constant mass flow through the plant, the furnace temperature must be raised continuously. Regular decoking of the furnaces is therefore necessary.
However, this problem can be reduced by selecting the proper tube metallurgy, such as Centralloy® ET-45 Micro or Centralloy® HT-E. These alloys are the universally preferred choice especially for “hot” outlet passes and with their carefully controlled specific additions can produce a dense and ”self-healing” oxide layer. This is especially effective in limiting coke formation and subsequent carburisation thereby increasing the overall Furnace performance and extending the Radiant Coil life.

Solutions for Steam Reformers
Our products - tailor-made for your specific requirements
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. Reaction gases at 450 - 650°C and pressures of 30 to 45 bar(g) are led through the reformer tubes that are filled with catalyst and heated to 800 - 900°C. This makes the tubes especially susceptible to so-called material creep.
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.
