Emerson Roxar corrosion monitoring system

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

The system will also help identify and track opportunity/high TAN crudes and their corrosive elements. Such crudes are less expensive but more corrosive than others with the system enabling the maximum amount of such crudes to be blended into the mix without increasing corrosion risk.

The Roxar corrosion monitoring system consists of electrical resistance (ER) and linear polarisation resistance (LPR) probes and weight loss coupons — all 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 also comes with advanced wireless capabilities and is compatible with the WirelessHART protocol as well as Emerson’s broad product refinery range. The system is part of a complete asset integrity solution and works alongside the Roxar Field Signature Method (FSM) and Rosemount pressure and temperature transmitters and repeaters.

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.
