The rising demand for energy is creating an urgent need to develop a method of energy production that is sustainable cost-efficient and a clean alternative to traditional fossil fuel processes. Nuclear power is an option that has the potential to resolve these issues. Coolants in a nuclear reactor must possess certain qualities such as high volumetric heat capacity high boiling point low vapor pressure resistance to radiation and thermodynamic stability. In recent years there has been an increased interest in molten salts as replacements for water. Despite the potential for increased corrosion rates in the containment vessel molten salts minimize the risk of explosions because they do not need to be pressurized. Fluoride salts are the preferred candidates for a coolant material but the associated expenses and safety hazards make them unattractive for prolonged utilization. Chloride salts offer a safer and more cost-effective alternative but can be highly corrosive. Therefore careful consideration is required in the material selection process of the containment vessel. In this project two stainless steels (UNS S31600 and UNS S30400) and one nickel-base alloy (UNS N06601) were immersed in a ternary molten eutectic LiCl-KCl-MgCl2 at 700°C. The post-test coupons were characterized with optical microscopy and scanning electron microscopy (SEM). The viability of the chloride salt as a replacement for the coolant material will be discussed.

Corrosion Control of Acid Flare Lines at Gas Treatment Facility

In any operating facility, the integrity of flare or relief lines should always be closely maintained, as it is one of the most important safeguards during plant upsets or emergency conditions. The most common damage mechanism in acid flare lines is acid gas dew point corrosion”. Corrosion in such systems is often dependent on fluid stagnation, especially in the presence of acidic water, during idle conditions.
The intent of this paper is to shed light on the efforts done in a gas treatment facility to identify different root causes that impacted or accelerated Acid Gas Dew Point Corrosion. These included design deficiencies, equipment integrity, and process challenges. Moreover, the paper provides findings and recommendations to avoid the occurrence of similar events in acid flare lines.

Corrosion Control of Pilings in Seawater: Buzzards Bay, Ma

This report assesses (1) the rate of corrosion of bare steel with and without cathodic protection, and (2) the effectiveness of various commercially avail able coating systems in preventing corrosion of steel piles in seawater. Eighteen coatings and four sacrificial anodes were tested on 24 sets (three piles per set) of ASTM A 36 or ASTM 690 steel H-piles exposed for 5 years at Buzzards Bay, Massachusetts. Performance ratings were established for the following coatings: organic, organic over metal-filled, organic over metal filled with cathodic protection, metallic organic over metallic, and organic with cathodic protection. It is concluded that sacrificial anodes of zinc and aluminum effectively reduced the corrosion rate of bare carbon steel (ASTM 36) piles in the immersed zone from 0.076-0.102 mm/yr (3-4 mils/yr) to zero, and the coating performing best was coal tar epoxy over zinc-rich primer.

Corrosion Damage of Injection String From the Deep Geothermal Well IDDP-2 in Reykjanes Iceland

The drilling of the second deep geothermal well drilled in the Iceland Deep Drilling Project (IDDP) at Reykjanes geothermal field was successfully completed in beginning of the year 2017. The previously drilled RN 15 production well 2500 m deep at the Reykjanes high temperature geothermal field was used as the base for the IDDP-2 well. The final depth of the IDDP-2 well reached 4650 m depth with a bottom hole temperature measured to be 427°C and a pressure around 340 bar. This made the bottom of the IDDP-2 well reach fluid at supercritical conditions and become the deepest geothermal well in Iceland. The well was then injected with coldwater for stimulation. During the injection the pumping was interrupted and the water in the well was able to heat up. When the injection string (pipe) was retrieved from the well extensive corrosion damages were apparent on the lowest part of the injection string. Cracks were also observed on a 500-meter interval of the injection string pipe starting from the bottom part. The injection string was visually inspected on-site and selected parts were chosen for further failure analysis. Specimens from the pipe and pipe connections were examined using an optical microscope scanning electron microscope (SEM) equipped with energy-dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD) technique. This was done to investigate and discuss the most probably cause of the corrosion damages. Additionally the hardness of specimens of the pipe were measured and compared to the NACE MR 0175/ISO 15156 standard. This paper covers the procedure and results of the failure analysis of the injection string from IDDP-2 well.

Corrosion Data Management Using 3D Visualisation and a Digital Twin

Product Number: 51320-14535-SG

There is a gap between the Integrity management systems used by companies to manage their assets and the needs of the CP engineer. Integrity management systems do not fully meet the needs of the engineer responsible for corrosion as they do not provide access and visualizations of all the data the engineer needs to make fast and informed decisions. There is also often no easy way to see the trends in the data, or easily access the relevant video and photographic data also recorded during the survey.

Data from surveys is normally contained in reports and EXCEL spreadsheets often with different measurement locations and inconsistent naming of the locations between reports. In this paper a system is introduced which enables engineers to manage and visualise in 3D CP survey data and provide access to all the relevant information through a 3D visual interface to any member of the teams. The software gives the engineer the ability to visualize in 3D the historical and predicted CP protection on the structure and the status of the anodes in the CP system. It also provides information on long term trends in the survey data.

By integrating the corrosion data with a simulation model a “digital twin” of the structure can be created to make predictions of the present and future protection of all parts of the structure. For example the engineer can easily use the software to systematically monitor the differences between the model predictions and survey data to identify anomalies and give early identification of problems which will require action.

The paper will describe the system developed and present applications of both the 3D corrosion data visualisation and the simulation based digital twin
