ABSTRACT
Refractories are construction materials designed to withstand aggressive service conditions at elevated temperatures. Generally, they serve as heat-resistant walls, coatings, or linings to prevent oxidation, corrosion, erosion, and heat damage. This chapter introduces the fundamentals of refractory materials and highlights their application in the oil and gas sectors. On the other hand, the methods for refractory materials characterization based on the properties are discussed in detail, and those properties’ relevance for the oil and gas sectors is deciphered. The chapter also highlights the application of different ceramics in a range of refinery units such as FCCU (fluidized catalytic cracking unit), SRU (sulfur recovery unit), etc. Finally, refractory manufacturing technologies for some of the important functional refractories used in oil and gas sectors, such as silica refractory, aluminosilicates, fireclay, etc., are discussed in detail.
