Managing Integrity And Corrosion Through Real-Time Prediction Modeling Approach – “Software Sensor” Concept

Managing Integrity and Corrosion Through Real-Time Prediction Modeling Approach – “Software Sensor” Concept
Available for download

Safe and stable operation of the process plant through its life cycle is an ultimate target of any integrity management system. Over the last decades, a number of possible ways and systems for managing plant integrity were described and implemented.1-4 A common path for all those efforts was to control and manage corrosion processes in a more-or-less systematic way by applying certain measures (monitoring techniques, material selection guidelines, operating procedures etc.) and performance indicators (remaining time-to-failure, inhibitor usage etc.). An effective corrosion and integrity management system, in theory, should be capable to “uncover” excessive corrosion incidents before serious damage occurs. Unfortunately, unexpected corrosion-related failures are still occurring in the petroleum industry.5 This situation stems predominantly from relatively poor data organization and management, leaving corrosion and key process information spread and hidden across different refinery functions and systems.

Corrosion and Integrity Management (CIM) covers several elements such as policy, strategy, resources etc. For effective implementation and supervision, these should be also supported by an integrated IT platform for analysis and communication. There’s a lot of hype about the Digital Transformation or the Industrial Internet of Things and their roles in supporting corrosion and integrity management. Digital Transformation at its core, is a simple concept – to harness the immense power of plant and process data in a seamless, cloud enabled digital environment to achieve superior process efficiencies, productivity, and reliability. This has important implications from connectivity of real time operating data, automated predictive analytics, increased collaboration – and finally, the quantitative impact on the process of managing corrosion. Over the last 20+ years, a number of research initiatives to effectively manage corrosion assessment, damage mitigation and asset integrity management in refinery unit operations were conducted by Honeywell International Inc. sponsored by global, industry-leading refining and engineering companies. Results of these research efforts formed the foundation for corrosion prediction models for multiple corrosion damage mechanisms including naphthenic and sulfidic corrosion, ammonium bisulfide corrosion and ammonium chloride corrosion. The by-product of these comprehensive efforts is a real time corrosion software sensor framework built around industry leading corrosion prediction models.

Managing aging reinforced concrete infrastructure is a complex and capital-intensive task, particularly in harsh marine and coastal environments. Corrosion from saltwater, coupled with wet and dry cycles, are particularly problematic for long-term durability of reinforced concrete. The Gulf Coast presents a challenge for maintaining service life of concrete structures that are exposed to high levels of chlorides, either by direct contact with salty or brackish water or by indirect contact with salt spray. Chlorides induce corrosion of the steel reinforcement which initiates cracking and spalling of the concrete, reducing the service life of the structure.

EIS is one of the techniques which is frequently used for studying electrochemical reactions on a metal surface in an aqueous environment. However, one of the main challenges in using EIS is the interpretation of results. Various interpretation methods and their associated uncertainties lead to ambiguous outcomes and often end up with a biased analysis One of the methods frequently used is the so-called “equivalent electrical circuit” method which models the response of and electrochemical system by matching it to that of a combination of “analogous” electrical circuit components, such as resistors, inductors, capacitors, etc.

UNS N06985 is a nickel-based alloy with additions of Mo, Cu and W. Because of its high strength and high resistance to stress corrosion cracking (SCC), cold worked UNS N06985 has been extensively used for OCTG (Oil Country Tubular Goods). The SCC initiation has been studied in Cl-H2S-CO2 containing sour environments; and the SCC resistance was often evaluated using slow strain rate testing (SSRT) for screening by short-term testing and using tensile or C-ring for verification by long-term autoclave testing exposures1. UNS N06985 showed high resistance to SCC at high temperatures in elemental sulfur containing environments with moderate chlorides2.
