Case study: Causes and countermeasures of a wall tube leak accident by an SNCR solution of a CO boiler in an RFCC process.

The article focuses on an accident in a carbon monoxide (CO) boiler used in the residue fluid catalytic cracking (RFCC) process, detailing its impact and implications for safety and environmental compliance. It discusses the mechanism of CO boiler operation, the adoption of selective non-catalytic reduction for reducing nitrogen oxides, and the risks associated with boiler water tube leaks emphasizing the importance of adherence to stringent environmental regulations and safety protocols.
