Al-Meshari, A., Saudi Basic Industries Corp.; Maity, M., Al-Zahrani, E., SABIC Technology Centre

Unusual pink coloration was noticed on the entire refractory brick wall in the radiant section of an ethylene cracking furnace of a petrochemical plant. The problem was investigated by evaluating the ..

How caustic stress leads to failures of incinerator caustic spray nozzles

Maity, M., Al-Zahrani, E., Al-Meshari, A., SABIC Technology Centre

Frequent failures of the waste spray nozzles in incinerators result in accelerated degradation of the refractory lining, requiring unscheduled shutdowns for repairs. A study was carried out to identify the factors that contributed to the nozzle failure and to prevent the reoccurrence of similar failures in the future.

Case history: Failure analysis of a syngas compressor

A first-stage impeller in a synthetic gas compressor failed after 20 years of service. The compressor is a six-stage centrifugal compressor driven by a steam turbine. This case history discusses the i..

Prevent external corrosion of boiler tubes under refractory lining

Maity, M., Biramov, K., Al-Zahrani, E., SABIC Technology Centre; Kareem, M. A., Eastern Petrochemical Co.

A leak developed on the water wall for several boiler tubes within five months of the commissioning of a plant boiler. In this case, the boiler tubes were partially covered with a castable refractory ..
