Overhead corrosion control within Upgraders’ operations has become increasingly important as units ramp up production rates to accommodate market demand. The industry has adopted a proactive approach to ensure prolonged equipment integrity, aimed at mitigating downtime, costly repairs and safety risks. When facilities rely on manual testing and stand-alone readings to adjust overhead operation, rapidly changing conditions can lead to severe corrosion episodes.

An integrated overhead monitoring and treatment program, which includes a combination of online crude overhead monitoring systems, real-time cloud-based data management and analytics, and customized chemical treatment, has proven to successfully prevent overhead corrosion at Upgrader facilities. Collaborating with a subject facility’s operation team, this integrated solution has enabled them to detect operating conditions that put the system at risk of corrosion, communicate the required adjustment, and monitor the impacts in real-time. The customized treatment recommended is composed of patented neutralizing amines designed to reduce the risk of salt deposition caused by traditional amines, by adequately controlling salting points within overhead systems. It is also comprised of a unique volatile filming chemistry that exhibits a wide range of pH stability, providing a tenacious protective barrier.

The implementation of this type of comprehensive overhead treatment solution can enable upgraders operating in a challenging market environment to extend asset useful life, reduce total cost of ownership and improve productivity.
