The topic of global warming as a result of increased atomospheric CO2 concentration is becoming the most important environmental issue that the world faces today.[1] The capture and separation of CO2, especially CO2 from large point source, for example, fossil-fuel-fired electrical power–generation plants is critical to stabilize the atomospheric CO2 concentration.[2] The existing commercial CO...

Corrosion, from long time before was a greatest problem in oil and gas industry and experts have always tried to combat this major problem. This has been given to the corrosion and inspection in oil and gas industry. Corrosion in oil and gas wells has the electrochemical mechanism, When the system reaches a temperature below the dew point, moisture is converted to liquid and many droplets occur...

Concrete corrosion is one of the most significant problems affecting valuable sewer infrastructure on a global scale. This problem occurs in the aerobic zone of the sewer, where a layer of surface corrosion develops on the exposed concrete and the surface pH is typically lowered from around 11-10 (pristine concrete) to pH 2-4. Acidophilic microorganisms become established as biofilms within the...

Replacing air with oxygen in coal-fired boilers (i.e. oxy-firing) combined with flue gas recirculation is a leading strategy to concentrate CO2 and assist in carbon capture and sequestration. A significant area of concern is the fireside corrosion with oxy-firing due to the higher CO2 levels in the combustion gas and potentially higher SOx and H2O levels. In order to investigate this complicate...

The objective of the work was to undertake a literature review on the subject of corrosion inhibition in the offshore oil and gas industry to understand the current issues. The application of chemical corrosion inhibitors can significantly reduce the rate of corrosion of carbon steel pipelines due to the presence of CO2 and/or H2S. An inhibited corrosion rate of 0.1 mm/year can typically be ach...

Air pollutants such as carbon dioxide play an important role in atmospheric corrosion processes and therefore in the degradation reactions occurring on metal surfaces exposed to an ambient atmosphere. It is known from macroscopic studies that ultraviolet (UV) light influences these surface reactions with respect to the reaction rate and the product formation itself even though the exact mechani...

The role of crude oil on carbon dioxide (CO2) corrosion has gained special attention in the last few years because of its signifi cance when predicting corrosion rates. However, the complexity and variability of crude oils makes it hard to model its effects, which can infl uence not only wettability properties but also the corrosiveness of the associated brine. This study evaluates the usefulne...

Future use of coal for power generation in the US depends on technologies being made available to capture and store CO2 emissions from power plants. A key candidate CO2 capture technology is oxy-firing of coal. Application of oxy-firing to existing power plants presents unquantified challenges as the characteristics of oxy-firing compared to airfiring have not been fully determined. This presen...
