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.
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.
University researchers find significant increases in both salinization and alkalinization of U.S. streams and rivers, which can influence the water's corrosivity.
A reaction between high-pH monoethanolamine and carbon dioxide formed a carbonate/bicarbonate solution that led to intergranular stress corrosion cracking.
A better appreciation of the various components of typical corrosion costs in the oil and gas industry could further facilitate their optimization.
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.
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.
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.
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.
In anticipation of the tightening restrictions on phosphorus and many of the metal-bearing compounds currently used in industrial cooling treatment, a “green” corrosion and scale inhibition technology was developed that contains no phosphorus while providing corrosion and scale control performance.
Corrosion professionals in North America and Europe have experienced another year of continued growth in career opportunities and salary levels, according to the 2015 Corrosion Career Survey conducted by Materials Performance magazine.
To successfully communicate the wide variety of corrosion-related issues affecting corrosion professionals today, MP is actively encouraging corrosion control professionals worldwide to submit technical articles to share their corrosion-related experiences with over 36,000 NACE International members around the globe.
For the foreseeable future, fossil fuels will continue to be the dominant source of the world’s primary energy production. There has been growing concern that the use of these carbon-based fuels produces greenhouse gases, principally carbon dioxide (CO2), which adversely affect the global climate and environment. One way to mitigate the problem is to use carbon capture, transportation, and storage (CCTS) techniques and systems.
Microbiologically influenced corrosion (MIC) refers to corrosion caused by the presence and activities of microorganisms—microalgae, bacteria, and fungi. While microorganisms do not produce unique types of corrosion, they can accelerate corrosion reactions or shift corrosion mechanisms. Microbial action has been identified as a contributor to rapid corrosion of metals and alloys exposed to soils; seawater, distilled water, and freshwater; crude oil, hydrocarbon fuels, and process chemicals; and sewage. Many industries and infrastructure are affected by MIC, including oil production, power generation, transportation, and water and waste water.
This article compares three water quality indices for
the evaluation of water to be used in industrial
processes in Iran. They include the Puckorious
Saturation Index, Langelier Saturation Index, and
Ryznar Stability Index. The most applicable index
for use in that country is suggested.
