Use of corrosion inhibitors (CI) to protect metallic equipment, especially carbon steel pipelines from corrosion has long been an established, effective, economic, and hence globally accepted technique. The oil and gas industry has been using CIs to protect the pipelines under various exposure conditions including sour and sweet services . Complete understanding of corrosion mechanisms under sour conditions and protecting pipeline steel under such conditions has always been a challenging task due to the complexity of such systems.

In most engineering and scientific applications, machine learning (ML) or artificial intelligence (AI) methods in general, are primarily oriented to design a statistical/heuristic procedure to predict the outcome of a system under new conditions. This mechanism aims at exploring non-evident correlations between inputs and outputs that are embedded in the data. However, a large body of this effort relies on black-box function approximations (e.g., neural networks) that have shown limitations to elucidate additional insights from the underlying physical process that generated the data. Thus, this type of knowledge is generated in a data-driven manner without fully explaining the physics governing the problem.

TR3T199-2020, Techniques for Monitoring and Measuring Corrosion and Related Parameters in Field Applications

Revised in 2020! Assessment of corrosion in the field is complex because of the variety of applications, process conditions, and fluid phases that exist in industrial plants where corrosion occurs. A wide range of direct and indirect measurement techniques is available, but each technique has its strengths and weaknesses. In some applications, certain techniques cannot be used. Some techniques can be used online, while others are used off-line. Commonly, more than one technique is used so the weaknesses of one are compensated for by the strengths of another. In other cases, a combination of different techniques can be synergistic, such as process sampling along with detection of corrosion upset.

The purpose of this technical committee report is to analyze the various techniques with respect to their benefits and limitations across the broad spectrum of industries in which they are used.

This revision incorporates Guided Wave Monitoring (GWM), On-Line Gas Chromatography (GC), and Acoustic Solid Detection (ASD) techniques and updates references to NACE standards.

Carbon capture and sequestration (CCS) is gaining greater importance in the industry transition to meet climate goals reducing carbon intensity. As the source of CO2 captured for sequestration widens to many more applications from oil and gas productions, power plants, refineries, chemical plants, steel manufacturing and other industries, the composition of the captured gas stream for sequestration sees various components. Some of the common impurities particularly from combustion processes are carbon monoxide, oxygen, SOx, NOx and others. Understanding the effect of presence of the various chemical species on material limits and maximum tolerance limits are crucial for safe operations of the assets. In one of the recent projects, there was a presence of CO in the CO2 stream, and it was imperative to identify the effect of this on the existing carbon steel pipeline. The pipeline was of X65 steel and fabricated for natural gas transmission. Wet CO-CO2 cracking is a reported degradation mode particularly as the CO concentration increases beyond 200 ppm in the gas phase or at partial pressures above 0.3 bar. This study is a combination of literature review of current state of art with respect to CO-CO2 cracking in carbon steel in presence of impurities and laboratory testing of welded X65 specimens exposed to CO concentration in dense (liquid) phase up to 1000 ppm and also in the presence of small concentrations of oxygen that also replicates some of the expected conditions in the project. The tests clearly indicate that the risk of CO-CO2 cracking is not significant up to the concentrations tested.
