In the production of carbon black pellets or powder as a filler for tires, industrial rubber products, plastics, electrostatic discharge (ESD) compounds, coatings or
other products, high-temperature corrosion is one of the challenges.
Whether you use the furnace black or thermal black process, we offer a range of HT tube grades for air pre-heaters (APH), oil pre-heaters, scrubbers, gas cleaning units and continuous rotary dryers.
The combustion of heavy petroleum, whether in a single- or double-shell preheater at 800 – 900°C in the reactor’s preheater, can be highly corrosive and lead to adverse deposits. However, the ability to recover process gas heat is a valuable way to reduce fuel consumption, increase feedstock flow, boost
production yield and reduce fuel consumption.
Alleima® 253 MA is suitable for air preheaters, depending on the impurity levels (sulphur, sodium, vanadium). Typical quantities run at about 14 tonnes per preheater. For reactor boilers, Sanicro® 28 is an excellent option due to its good resistance to sulphuric acid. For scrubbers and gas cleaning units, Alloy 825 is often used but can be replaced by Alleima® 2RK65™ and Sanicro® 28. Alleima® 253 MA tube is highly suitable for pipe lifters.
