Safeguard FCCU Operations with Advanced Power Recovery Trains Control

CCC’s unified approach to PRT control delivers seamless coordination of expanders, air blowers, and steam turbines

Power Recovery Trains (PRTs) play a critical role in recovering energy from flue gases and converting it into mechanical power in Fluid Catalytic Cracking Units (FCCUs). CCC’s advanced control system coordinates the expander, air blower, and optional steam turbine to maintain optimal operating conditions across a wide range of scenarios, including normal operation, grid disconnects, and breaker trip events.

This article outlines how CCC’s control applications manage speed, performance, surge protection, and steam flow, ensuring safe and efficient transitions between motoring and generating modes. You will see how control features, such as loop decoupling and load shedding, protect the PRT during upset conditions, all while maintaining a consistent air supply to the reactor and regenerator.

This is a valuable read for engineers and operators working with PRTs in FCCUs and other energy-intensive processes, featuring real-world system architecture, control logic breakdowns, and detailed startup sequencing information.
