Emerson Roxar Corrosion Monitoring System

Click2Contact

Emerson Process Management has launched a corrosion monitoring system for refineries. The Roxar Corrosion Monitoring system, consisting of wireless-based probes, will provide refineries with flexible, responsive and integrated corrosion monitoring.

Combined with the Emerson’s Field Signature Method (FSM) technology, a non-intrusive system for monitoring internal corrosion at the pipewall, refinery operators will be able to access more comprehensive corrosion information and corrosion rates, leading to improved operator insight and control over assets. The system will ensure optimal production processes and reduce refinery downtime, with only the necessary amount of corrosion inhibitors being injected to meet environmental requirements.

The corrosion monitoring solution comes with fast response times, continuous measurements and installation in the plant’s most critical and often inaccessible sections. It will help identify and track opportunity/high TAN crudes and their corrosive elements.

The corrosion monitoring system consists of electrical resistance (ER) and linear polarisation resistance (LPR) probes and weight loss coupons — all coming with high temperature ratings, high resolution (10–100 nm) and fast response times. The ER and LPR monitoring functions are also available on the same instrument and a 20 m cable provides added flexibility with respect to positioning, optimised signal routing, easier maintenance and probe replacement.

The system can be installed in a number of refinery applications, including side streams, cooling systems and in addressing naphthenic acid corrosion in high-temperature distillation processes. It can also tackle increased corrosion triggered by high velocity and temperatures, malfunctioning desalting units and high sulfur content.
