Refining and petrochemical operations, such as fluid catalytic cracking units, naphtha reformers, incinerators, and furnaces subject refractory linings to a variety of aggressive actions, such as erosion, spalling, slagging, and chemical attack. A number of different types of monolithic refractory material are used to resist these actions. The types of refractory failure commonly experienced in refineries and petrochemical plants are discussed and methods of repairing or replacing the deteriorated areas are outlined. The effect of placement techniques, curing conditions, and start up procedures on the serviceability of repaired sections is also discussed.
