Multiple heaters required full performance restoration promptly, safely, and within a strict timeline. The complexity of the project, involving multiple heater configurations in a high-risk environment, rendered conventional cleaning methods infeasible, prompting the refinery to turn to CTP Environment for the task.  ### The Challenge The shutdown involved multiple heaters in different configurations—radiant, convection, and Air Pre-Heater (APH)—all of which were significantly fouled, degrading performance. The tight shutdown schedule left no room for error, and adjacent equipment, including refractory, required protection throughout the operation. Conventional cleaning methods could not meet the refinery's combined performance, safety, and timeline requirements. ![neutrol2-1](https://info.ctpenvironment.com/hs-fs/hubfs/neutrol2-1.png?width=446&height=585&name=neutrol2-1.png) ### The Solution CTP utilized its proprietary NEUTROL® cleaning process, engineered to achieve full performance recovery under demanding shutdown conditions. Before any cleaning began, the team installed a custom-engineered tarping system to fully protect surrounding critical assets, including fiber refractory. Highly trained specialists executed the installation, ensuring total containment and operational safety throughout the project. With all protections in place, the CTP team initiated the NEUTROL® dual-action process, which combines: - Targeted chemical action to break down and neutralize deposits - Powerful mechanical action to eliminate remaining fouling This method provided uniform, deep cleaning across each heater section while safeguarding equipment and refractory.   ### The Results CTP completed the full cleaning scope within the scheduled shutdown, treating every heater zone without incidents or equipment damage. The NEUTROL® corrosion inhibitor formulation preserved the integrity of all protected assets. All heaters were restored to Start of Run (SOR) condition, the reference point for maximum thermal efficiency at the start of an operating cycle, delivering improved heat transfer performance and a reliable, optimized restart for the refinery. ![BottomCTA-Image-2](https://info.ctpenvironment.com/hs-fs/hubfs/ctpenvironment%20-%20Feb_2026/images/BottomCTA-Image-2.jpg?width=1920&height=640&name=BottomCTA-Image-2.jpg) ## Request a Quote.
