Preventing Internal Corrosion in Oil and Gas Field Pipelines

Preventing the internal corrosion of crude oil, natural gas, and water injection pipelines involves numerous steps, which operators should follow to ensure the integrity of oil and gas field pipelines that are essential for uninterrupted production.

Vapor Corrosion Inhibitors for Tank Bottom Corrosion Control

A study was recently conducted to determine the viability of vapor corrosion inhibitor (VCI) technology in mitigating corrosion. Overall, VCIs were found to be effective in mitigating corrosion when recommended dosages are used, and they could also be used in combination with impressed current CP systems.

New Steel Pickling Process Applied Without Nitric Acid

The usual challenge for stainless steel pickling involves removing all scale, iron contamination, and welding oxides to achieve a fully passivated surface with an even, clean, and aesthetic finish. In this case, a new nitric-acid-free process was installed at a large beer barrel plant in Spain.

Underdeposit Corrosion in Crude Tower Overheads

Ammonium chloride corrosion is an aggressive form of localized, underdeposit corrosion commonly found in overhead equipment and piping associated with crude units.

Corrosion Issues of Carbon Capture, Utilization, and Storage

When steels corrode under a high-pressure, high-temperature multiphase environment containing supercritical carbon dioxide, various gas impurities, salts, crude oil, and solid particles merit further investigation.

The Science Behind It: A ‘Cultural’ Change in Detecting Microbiological Activity

Molecular microbiological methods (MMM) are becoming more commonly used as an alternative for culture-based methods for estimating bacterial numbers in oilfield systems.

Corrosion Prevention Using Real-Time Data in Oil Fields

In corrosion monitoring of oil and gas fields, there are many techniques that can provide data. Modern high-resolution corrosion monitors, including electrical resistance probes, are available. These instruments can be installed in key locations and connected to a control room computer.

Linking Microbiologically Influenced Corrosion to Microbiological Activity Using Molecular Microbiological Methods

While there are solutions to mitigate microbiologically influenced corrosion, a big challenge is to make the connection between corrosion damage and the activity of microorganisms.

Study: North American Waterways Becoming Saltier, More Alkaline

University researchers find significant increases in both salinization and alkalinization of U.S. streams and rivers, which can influence the water's corrosivity.

Internal Stress Corrosion Cracking of Shale Gas Flowlines

A reaction between high-pH monoethanolamine and carbon dioxide formed a carbonate/bicarbonate solution that led to intergranular stress corrosion cracking.

Corrosion Management and Cost Optimization

A better appreciation of the various components of typical corrosion costs in the oil and gas industry could further facilitate their optimization.

Results Posted for NACE International’s 2016 Annual Corrosion Career Survey

Average annual salaries in 2016 are reported for corrosion professionals in the United States, Canada, United Kingdom, and Europe. A slight gain was seen for the United States and United Kingdom, while a larger increase was recorded in Canada.

A Multifunctional Additive for Controlling Inorganic Foulants in Industrial Water Systems

This article presents performance data on polyamino polyether methylene phosphonic acid (PAPEMP) on various mineral scales commonly encountered in boiler, cooling, desalination, geothermal, gas, and oil systems.

Chromate Primer Alternative Uses Carbon Nanotubes Modified with Corrosion Inhibitors

Scientists have developed a non-chrome primer system by incorporating carbon nanotubes (CNTs) modified with organic corrosion inhibitors into an epoxy-based resin. The goal of the coating development effort was to identify promising CNT-containing non-chrome primer formulations that perform comparably to traditional chromated ones.

Corrosion Management and the Significance of Regular Reporting

Regular inspection, monitoring, sampling, and chemical treatment activities are needed to mitigate corrosion. Data are not always adequately reported on a regular basis, however, which could gradually render an asset integrity management system less effective.
