The production of sodium hydroxide (NaOH) can be carried out by the membrane, diaphragm or mercury process. The biggest difference between these processes, with regard to fluid composition, is that the caustic soda (NaOH) produced by the diaphragm process has a higher chloride content during its production process.

Such aggressiveness in the environment generally calls for the use of special materials to increase the useful life of the equipment and avoid unscheduled shutdowns in the production unit.

Using a Computational Galvanic Model in a Fracture Mechanics Framework to Improve Material Degradation Prediction

Although computational methods have been separately developed to predict corrosion and fatigue crack growth rates for metallic structures, challenges remain in implementing a methodology that considers the combined effects. In this work the output from a galvanic model is used to determine the spatial distribution of corrosion damage; providing a guide for the location of discrete corrosion damage features that can be analyzed using stress fields from structural models. In order to build confidence in this approach the galvanic models are validated by comparing predicted results to surface damage measurements from test specimens subject to ambient atmospheric exposure. There was good comparison between the predicted spatial distribution of corrosion damage and the measured surface damage profiles obtained from the galvanic test specimens. Following this exercise novel computational corrosion damage features were developed to represent simplified cracks shapes emanating from corrosion pits. Stress intensity factors (SIF) for these newly developed hybrid pit-crack features were determined and these solutions compared to cases where the pit is assumed to be an equivalent crack. The impact of the local, cavity induced stress field, on the SIF solutions is discussed. Building on these findings a fatigue crack growth simulation was performed using an initial flaw emanating from a hemispherical cavity (corrosion pit) located at the edge of hole in a plate. A reasonable comparison, of the predicted number of crack growth cycles, to available experimental test results was achieved.

Using Atmospheric Plasma for Enhance Coating Adhesion to Limit the Onset of Corrosion

Protecting and maintaining assets in highly corrosive environments has been a challenge for centuries. Assets that require precision coating removal around compromised structures require a precision tool that does not impact the structure leading to failure. Removal of any metal or damage to surfaces must be avoided in these scenarios, which disqualifies highly abrasive removal methods such as blast cleaning, needle-gunning, and water-jetting.

Using DC Decouplers to Maximize Isolation of Cathodically Protected Structures

Product Number: MECC23-19878-SG

Author: Jay Warner

Publication Date: 2023

$20.00

Cathodic Protection (CP), when properly applied, is an effective technique to minimize the natural corrosion process that occurs on pipelines, tanks, and other buried steel structures. To maintain effective CP coverage with minimal current demand, the structure must be well-isolated from earth for DC current flow. This is commonly accomplished using high resistance coatings, isolation joints, dielectric fittings and isolation pads.

Using Flexible Steel Pipe to Rehabilitate Aging Pipelines

Product Number: 51323-19013-SG

Author: David Gregory, Shawn Poworoznik

Publication Date: 2023

$20.00

This paper highlights a successful rehabilitation of a regulated steel line with flexible steel pipe. The pipeline resides under jurisdiction and was approved by both state and federal pipeline safety administrations. Upon completion, the rehabilitated system restored transmission while also reducing overall operating risk. Use of the flexible steel pipe allowed the operator to utilize a dual-containment design while also implementing real-time continuous annulus monitoring on multiple interfaces, effectively reducing risk to environment and local residents.

Using Galvanic Modeling and Aerosol Spray Testing to Understand How Changes in Salt Loading Can Impact Atmospheric Corrosion

Corrosion is not just a sustainment concern that impacts the availability and safety of critical structural assets; it is also a damage mechanism that should be considered during the initial design phase. By considering the corrosion process and associated preventive strategies during the design phase it is possible to reduce total ownership cost and improve equipment readiness. The Department of Defense spends more than $23 billion each year to control corrosion on aircraft and other equipment in its operations around the world.

Using Guided Waves Testing (GWT) for the Integrity Inspection of Pipelines

Product Number: 51324-20599-SG

Since its commercial launching, guided wave testing (GWT), a.k.a. long-range ultrasonic testing (LRUT), has been largely applied in the oil and gas industry for the inspection of pipelines, due to its faculty for screening large lengths of pipeline from a single point of contact. This capability has made the GWT one of the “other technologies” most employed in the integrity inspection of pipelines; however, regardless of its broad usage, industry standards guiding the integrity management of pipelines do not provide a clear framework for the use of GWT, neither do they agree on the role that it plays in the integrity assessment process. For example, some standards classify the GWT as a standalone corrosion integrity assessment method, while others reference it as an inspection technique, and others allocate it as a corrosion monitoring technique. This paper makes a comprehensive review of the involvement of the GWT in the pipeline’s integrity management process and intends to provide a clear framework for the use of guided wave testing (GWT) as an integrity inspection method for pipelines.

Natural gas pipeline operators often rely on gas and liquid sample analysis as well as bacteria serial dilution to determine if corrosive conditions exist within the pipeline. When corrosive conditions are suspected, additional monitoring methods such as corrosion coupons or probes are employed. One of the challenges faced by operators is determining what constitutes “corrosive conditions” because existing regulations do not define gas or liquid compositions that are corrosive. In this study, over a decade’s worth of sampling and corrosion monitoring data collected by a natural gas pipeline operator are assessed using machine learning in order to determine the parameters with the greatest influence on corrosion rate. This work combines over 2,300 gas tests, liquid samples, solid samples, and bacteria tests in an attempt to determine if the thresholds the company is using are reflective of where corrosion is actually occurring based on over 1,700 coupon analysis results within an operator’s unique system. The results from this study can be used to guide future sampling practices so that effort is spent collecting the most meaningful data and improving the ability to identify corrosive conditions.

From day to day, Robots advance from testing in labs to operating in the outside world. The
industrial application of Robotic technologies continually increases, providing unique solutions for
different challenges. Flare System is an important and critical equipment required for continuous
safe operations for any petrochemical plant addressing proper burning of excess hydrocarbon
gases, unusable gases which cannot be recovered or recycled, and gas flaring protects against
the dangers of over-pressure. This paper discusses the different types of robotic inspection,
advantages, and limitations based on actual site demonstrations. As an innovative case, here to
introduce actual business case for close aerial inspection and surveying technique to avoid
polyethylene plant shutdown and providing a reliable inspection technique for on-stream integrity
evaluation for the flare tip. Drones, formally known as unmanned aerial vehicles (UAVs), are a
flying robot that can be remotely controlled, and offer an innovative inspection method launched
between 2006-2008 for Engineering professional aerial inspection and surveying using Remotely
Operated Aerial Vehicles (ROAVs). The visual inspection detection accuracy of (ROAV) offer
higher than the normal visual inspection and easily approach all the flare structure from four
directions. Drone inspection cost is competitive considering the cost of maintenance to dismantle
the flare tip. Drone inspection can be used to assess the elevated flare parts for any seriously
damage in order to define a clear maintenance scope ahead of shutdown.
