investigation of Corrosive Effects of sulphur dioxide oxygen and water vapour on pipeline steels
International Journal of Greenhouse Gas Control, 2013Co-Authors: Aki Sebastian Ruhl, Axel KranzmannAbstract:Abstract Pure carbon dioxide is reported not to be Corrosive. In the presence of impurities corrosion of pipelines is a risk CCS systems are exposed to. Allowable concentrations of gas constituents and humidity are not yet fully determined. Therefore, three different materials, two pipeline steels and pure iron, have been exposed to continuous flows of carbon dioxide with varying concentrations of water, sulphur dioxide and oxygen to approach carbon capture and storage conditions. Corrosion Effects occurred when condensates containing sulphurous and sulphuric acids precipitated. A variety of different morphologic characteristics in direct vicinity were found. The surface appeared to be uniformly corroded, and no significant localized corrosion was found. Although X-ray spectroscopy revealed an oxygen depleted layer in the corrosion build-up (indicating the presence of sulphides), only iron sulphite and sulphate have been detected with X-ray diffraction. Material and thickness losses were severe for elevated humidity and 650 ppm sulphur dioxide.

Corrosive Effects of pb17li water interaction
Fusion Engineering and Design, 1991Co-Authors: P Agostini, G BenamatiAbstract:Abstract The interaction between Pb17Li and water, as a consequence of a localized tube microcrack, has been studied. Two experiments were performed in which a low quantity of steam was injected into the lithium lead. The artificially machined microcracks, simulating a real microcrack in an AISI 316 heat exchanger tube, had a maximum area of 0.003 mm 2 . No blockage of the microcrack was observed during the tests. No significant damage was observed on the microcracks geometry, probably because of the short test time. A layer of reaction products having a high melting point was formed around the test section. First analytical results seem to confirm the presence of lithium hydroxide in the reaction products.

Corrosive Effects of salt hydrate phase change materials used with aluminium and copper
Journal of Materials Processing Technology, 2006Co-Authors: Anthony J Farrell, Brian Norton, David KennedyAbstract:Abstract A disadvantage of phase change materials (PCMs) as thermal energy storage media is corrosion when in direct contact with metal piping, plates or housings. The corrosion rates of aluminium alloys and copper used in heat exchangers in the air conditioning industry has been measured along with metallographic examinations following corrosion tests. Ways of preventing corrosion of copper and aluminium by these PCM materials are discussed.
