Boiler Technology to Monitor and Control Corrosion In Ethylene Plant Steam Generation Process

摘要

Maintaining reliable and efficient operations in the Ethylene Plant SteamGeneration Process requires good control of corrosion in the pre-boiler and boiler watersystems. The high purity water and high heat flux conditions require chemical treatments tobe monitored and controlled in tight ranges. Achieving this level of control can often bedifficult with traditional methods. New state of the art systems provide real time monitor &control capabilities to proactively respond to system stresses and maintain tight control.This paper will discuss conventional boiler water treatment programs and how theirapplication often results in reliability issues. In contrast, the paper will also discuss the use ofnew state of the art technology and its impact on corrosion monitoring, corrosion control,system reliability, and total cost of operations.
