SCOPE Fusion HTE –the steam cracker tubing of the futureThe steam cracker is the heart of your ethyleneand propylene production facility. Integratedinto healthy supply and discharge lines, SCOPEFusion HTE provides highly reliable and durableoperation and ensures the maximum efficiencyof your steam cracker. Repair and maintenanceof the furnace itself or of directly adjacentperipherals, on the other hand, require costlyshutdowns.The inevitable formation of coke in a typicalsteam cracker environment is a complex phenomenon. Coke is deposited on the surface ofthe centrifugally cast tubes where it reducesthe effective cross-sectional area while addingundesirable thermal insulation. The furnace isat risk of suffering a heart attack.In order to maintain the desired crackingefficiency, however, the required furnacetemperature can be increased for a whilelonger – although this requires considerableadditional energy. But sooner or later, the plantreaches the point where it has to be shut downso that the radiant coil can be decoked.It‘s a never-ending cycle with which you, asa plant operator, are all too familiar. Basedon decades of experience, extensive researchand exhaustive testing, S C continuouslyoptimizes its product range. Our objective isto achieve maximum energy efficiency, thelongest possible maintenance intervals, andminimum downtime for your plant.With SCOPE Fusion HTE,we have achieved a breakthroughto a whole new level.It combines the high quality alloy HT E, whichhas proven effective for more than a decadenow, with a mechanically created 3D tubedesign, which both effectively slows the cokedeposition process and optimizes the crackingof the feedstock in the steam cracker.And it lets the heart of your plant continue tobeat strongly for a long, long time.“The SCOPE design is superior to all bare and profile tubes in termsof efficiency and selectivity, but the alloy Centralloy HT E makesSCOPE Fusion HTE the best profile tube in the world!”Dr. Dietlinde Jakobi4

Strengthen the heartof your plant

SCOPE Fusion HTE – intelligentprofile meets superior materialThe use of an intelligent profile in steam cracker tubes can considerably raise the selectivity of aplant. Use of the right alloy as tube material can greatly inhibit coking and carburization processes.But what happens when innovative tube design meets a perfect material? SCOPE Fusion HTE isearning top marks for performance and endurance and has distinguished itself as by far the bestof today‘s steam cracker tube systems.The use of HT E – which has a proven track record as the most effective alloy to inhibit cokingand carburization – extends required decoking intervals by up to ten fold, thereby minimizingdowntime while also protecting the plant. The innovative 3D design, which can be adapted tomeet customer-specific requirements, increases selectivity and ethylene yield while savingenergy at the same time.SCOPE Fusion HTE helps you get the most out of your steam cracker!6

SCOPE Fusion HTE is theright choice for many reasonsThe design goals for the SCOPE Fusion HTE tube – an entirely new development –were particularly extensive, because they specifically aimed to avoid the knownshortcomings of existing profile tubes. The objective was to achieve the highestpossible plant availability while optimizing the energy efficiency of a steam crackerequipped with the SCOPE Fusion HTE tube at the same time.For example in combination with significantly increased selectivity and improvedethylene yield, the benefits add up to a fast return on investment for the operator.It is the unique combination of the proven HT E alloy with the innovative SCOPEprofile which leads to some truly extraordinary results.Up to ten times longerproduction runs!Centrifugally cast tubes ratherthan forged tubesDuring operation, the centrifugally castmaterial together with the unique profileof the SCOPE Fusion HTE tube facilitatea relatively low material temperaturewhich, moreover, is distributed uniformlyacross the tube shell. In combination withthe exceptionally strong HT E material,both coking and carburization of the steelis greatly inhibited.S C looks back on decades of experiencein the production of centrifugally casttubes. This material has properties thatmake it particularly suitable for use insteam crackers.The convenient result: less downtime,less frequent maintenance, lowermaintenance costs, less wear and tearon the plant – and up to ten times longerproduction runs.In combination with the unique SCOPEdesign, it provides for better heat transfer,lower tube metal temperatures, and moreuniform gas temperature distribution thanwith conventional tubes, as well as anoptimal pressure drop within the tubes.Internal Profilesfor maximum results

Profile Tube technological”Leap forward”SCOPE Fusion HTE increases selectivityand ethylene yieldBoth the profile itself – which can be individuallytailored to meet requirements inside the unit –and the mechanical production process for SCOPEFusion HTE tubes were developed from radicalinnovative new thinking and technology and offerclear advantages over other tubes on the market.The SCOPE profile is designed to achieve the targettemperature inside the tube faster and to distributeit more uniformly, which has a positive effect onboth the selectivity and the yield.Measurements have shown that the simultaneouscombination of high heat transfer and a balanced gastemperature inside the tube results in significantlyhigher product selectivity. Together with the higherflow rate in the SCOPE Fusion HTE tube and thegreatly extended decoking intervals, this providesmajor cost benefits.This is the only tube that combines the innovativeSCOPE profile with the proven Centralloy HT Ematerial. It forms an extremely stable protectivelayer on the inner wall of the tube and acts againstcatalytic coke formation as well as carburization ofthe tube material.As a SCOPE Fusion HTE customer, you reap thebenefit not only from the unique technical advantagesof this innovative tube system, but also from ourS C service management.Controlled flow, minimized pressure dropThe SCOPE Fusion HTE tube optimizes heat transferfrom the outer surface of the tube into the gas streamand improves the flow dynamics of the gas stream,which is controlled by a specifically designed radialswirl flow.Operating TemperatureWindow-SCOPE Fusion HTE vs.Bare Tubes (schematic graph)8SCOPE Fusion HTE: Full serviceFirst, we prepare an exact specification profile forthe tubes used in your plant – on request, weprovide you with on-site support during operation, inorder to get a complete picture.
