VDM Alloy 699 XA (UNS N06699, EN Alloy number 2.4842) is a new alloy, which was developed for applications in the petrochemical industry under metal dusting conditions between 400°C and 800°C. Important properties of a new material are corrosion resistance, such as to metal dusting, oxidation resistance, and workability versus high temperature strength, which are essential for industrial applications. Currently, there are material solutions which demonstrate good metal dusting resistance, but may have issues with workability. In addition, there are also minimum requirements concerning creep resistance. It is therefore of fundamental interest, in the context of alloy design, to develop materials that has these important properties and satisfies the needs of industrial users.

IOW Analysis With Installed UT Sensors: How Process Changes Impact Corrosion Rates

Product Number: 51322-17611-SG

Publication Date: 2022

Many asset owners struggle to identify the root cause of fluctuating corrosion rates due to unreliable inspection data. Facilities worldwide are tasked with monitoring thousands of Condition Monitoring Locations (CMLs) with established NDE techniques such as manual ultrasonic testing and radiography. While these techniques can provide valuable “snapshots” of the condition of particular locations, limitations and inherent errors can compound leading to ill-advised decision making. Manually taken thickness data can vary greatly and result in unwarranted complacency or excessive and costly inspections.

Many asset owners struggle to identify the root cause of fluctuating corrosion rates due to unreliable, infrequent, or sheer lacks of quantity of inspection data to make informed decisions on asset health. Facilities worldwide are tasked with monitoring thousands of Condition Monitoring Locations (CMLs) with established NDE techniques such as manual ultrasonic testing and radiography. While these techniques can provide valuable “snapshots” of the condition of particular locations, limitations and inherent errors can compound leading to ill-advised decision making.

One of the pillars of the fourth industrial revolution (4IR) is to let machines make decisions on behalf of humans; this paper describes new technology that allows machines to decide inspection programs and field validation and testing of results. The technology described is a part of integrity management, and uses data, statistics and expert decisions to design inspection programs. These inspection programs are an important part of the safeguarding of equipment to maintain production and safety.
This technology is a data-driven predictive model of material loss from corrosion, based on domain expert input and historical data in the form of non-destructive testing (NDT) tests. The technology trends is based on historical data and SME input, while accounting for uncertainties in NDT measurements, with uncertainties in historical trends and uncertainties in future trends. This produces a more realistic failure prediction to enhance existing RBIs and adds safety by improving on early detection of trends in data. In total, this enables the machine to update inspection plans autonomously, reducing the number of inspections significantly.
The paper also describes how the technology can be developed further to use production data and integrity operating windows to improve predictions, deal with localised corrosion and assess if the test points on a corrosion circuit are sufficient, can be reduced in number or should be manually evaluated by adding more test points.

IR 4.0 Knowledge Technology for Managing Risks Associated with Refining Various Crudes

Product Number: MPWT19-15463

Author: Bilal Abdallah, Maana, Inc.

Publication Date: 2019

$0.00

Knowledge technology provides energy companies with knowledgeable applications that help them make better decisions faster in all decision points. One such knowledge application (CrudeFlex) is related to supporting the decisions of purchasing certain crudes to be processed in certain refineries through properly evaluating the risks associated with processing such crudes.
In this paper, we discuss the basic concepts of knowledge modeling and how specifically CrudeFlex was developed as a knowledge application, how it works and how rifineries are leveraging it to strengthen their competitive edge and proactively evaluate and manage risks associated with the crudes.
The new generation of knowledge applications are powered by a combination of computational knowledge graphs and computational algorithms. These algorithms encode the expertise of subject-matter experts, such as process engineers and combine their experience with decades of historical data extracted from databases, documents, and sensors in addition to ever-growing corpus of technical research to support better decisions faster. This technology enriches and combines companies’ internal siloed data with public data to create an integrated digital knowledge layer. Engineers can evaluate and manage the risks associated with known processing and new crudes in any of their refineries.
Refining engineers have easy access to knowledge related to people, equipment, vendors, crudes and more, so that they can make better, more informed decisions faster. In this paper, we show how the application of such algorithms helps the reading of hundreds of thousands of historical reports to harvest knowledge about the risks, and store the extracted knowledge in an enterprise digital knowledge layer, saving millions of dollars by enabling experienced engineers to make significantly better decisions faster through using the harvested and captured knowledge.

Microcosm is defined as “A community, place, or situation regarded as encapsulating in miniature the characteristics, qualities or features of something much larger”. By examining a “microcosm” one can look at how an overall system or market operates and infer assumptions and regard changes by looking at manageable data sets. This paper will examine a “microcosm” of the water tank recoat market. Data was collected from the website “Civcast USA”. The projects that were examined were water tank recoats in the Texas Market.

The manufacturing and field experience of high strength low alloy (HSLA) steel plates produced by Thermo-Mechanical Controlled Process (TMCP) are well defined in industry standards and literature. The TMCP method consists of a well-prescribed rolling pass schedule followed by accelerated cooling that leads to a fine-grain microstructure with the desired mechanical properties of the produced plates.
Quite recently, this TMCP process resulted in detrimental local variations with hidden hardness variations on pipe ID, so-called Local hard Zones (LHZ).

Is it MIC or Pitting Corrosion? An Insight in a Common Overlapping

Product Number: 51320-14719-SG

Author: Mohammed Al Muaisub

Publication Date: 2020

$20.00

Although Microbiologically Influenced Corrosion (MIC) is a critical damage mechanism that had been researched for decades in different environments, yet diagnosing a specific industrial failure to be attributed to MIC can still be challenging. The challenge of accurately identifying an MIC failure is partially due to the similarity of the failure morphology with other damage mechanisms, e.g., pitting corrosion due to chloride. Furthermore, the variously proposed initiation and propagation mechanisms for different types of bacteria may illustrate to the failure analyst that the MIC mechanisms are not yet well established. The confusion of MIC failure identification could also be aggravated by the fact that the presence of bacteria in a system does not necessarily mean that MIC is the culprit. Therefore, this paper will shed some light on the overlapping areas between MIC and pitting corrosion, especially the morphology of the attack. Moreover, several steps will be highlighted and discussed on how to correctly identify if MIC is the culprit in a specific failure.

Is Surface Charge Important for Scaling on Polymeric Matrices?

The formation of inorganic scale deposits in numerous waters mediated industrial applications takes place by heterogeneous nucleation and crystal growth. These processes depend on the supersaturation of the solution in contact with respect to the depositing salt, on the characteristic features of the surface on which scaling takes place, temperature, fluid velocity and the presence of foreign substances. Despite the importance of the surface on which salts form, very few studies have focused on this issue.
