Available in PDF, EPUB and Kindle. Book excerpt: The aim of this research was to study the effectiveness of a typical oilfield corrosion inhibitor, which is considered to be a green inhibitor (non toxic to the environment) in controlling internal corrosion of welded X65 pipeline steel in brines saturated with carbon dioxide at one bar pressure, under dynamic flowing conditions, over a range of temperatures. Several experimental configurations were used ranging from a simple flat plate design to a novel rotating cylinder electrode, to allow high shear stress to be achieved. The rotating cylinder electrode (RCE) apparatus was designed to allow steel from the weld metal, heat affected zone (HAZ) and parent material to be galvanically coupled and tested in high shear stress conditions. In producing the RCE, the three regions of the weld were identified by optical metallography and samples of each were machined to produce cylindrical electrodes, which were mounted on a motor driven shaft. Electrical connections were made to the three electrodes via a high quality slip-ring assembly. The galvanic currents flowing between the regions of the weld were recorded using zero-resistance ammeters and their self-corrosion rates were found by uncoupling the electrodes and performing polarization resistance measurements. For static conditions the inhibitor had an effective performance and after a short initial period during which film formation took place, at longer exposure times a dramatic reduction of corrosion rate was obtained. Under flowing conditions, both the galvanic currents and the self-corrosion rates were found to increase with the shear stress, as the rotational speed of the RCE was increased. The total corrosion rate of each weld region was assessed from the sum of the self-corrosion and galvanic contributions. In most cases, the weld metal and HAZ were shown to be cathodic to the parent material and this was considered to be a desirable situation as localised corrosion of the weld was minimised. However, in some ci.

This book was released on 2022-10-04 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanomaterials for Carbon Dioxide Capture and Conversion Technologies focuses on the applications of nanomaterials for CO2 capture and conversion. The book highlights the need for CO2 mitigation, followed by the basic principles for CO2 capture and conversion, using different nanomaterials, while also discussing and highlighting challenges and perspectives. Abundant CO2 emissions from industries and the transportation sector are a threat to the planet due to overwhelming concerns regarding CO2-induced climate change. Nanomaterials are being widely investigated for CO2 capture and conversion processes. Nano absorbents, adsorbents and nanomembranes for CO2 capture, nano catalysts for catalytic CO2 conversion, and chemical fixation of CO2 are some of the broader applications of nanomaterials for CO2 mitigation. Helps readers understand the basic mechanisms and theories behind CO2 capture and conversion using nanomaterials Provides information on the range of nanomaterials types used in CO2 capture and storage systems Assesses the major challenges for integrating nanotechnology into carbon dioxide capture and storage systems at an industrial scale

Download or read book Corrosion of Weldments written by Joseph R. Davis and published by ASM International. This book was released on 2006-01-01 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corrosion failures of industrial components are commonly associated with welding. The reasons are many and varied. For example, welding may reduce the resistance to corrosion and environmentally assisted cracking by altering composition and microstructure, modifying mechanical properties, introducing residual stress, and creating physical defects. This book details the many forms of weld corrosion and the methods used to minimize weld corrosion. Chapters on specific alloys groups--carbon and alloy steels, stainless steels, high-nickel alloys, and nonferrous alloys--describe both general welding characteristics and the metallurgical factors that influence corrosion behavior. Corrosion problems associated with dissimilar metal weldments are also examined. Case histories document corrosion problems unique to specific industries including oil and gas, chemical processing, pulp and paper, and electric power. Special challenges caused by high-temperature environments are discussed. Commonly used methods to monitor weld corrosion and test methods for evaluation of intergranular, pitting, crevice, stress-corrosion cracking, and other forms of corrosion are also reviewed.
