Ionic liquids as diathermic fluids for solar trough collectors’ technology: A corrosion study

Abstract: The AISI 304 and AISI 1018 steels (frequently used in solar collectors' plants) in contact with four different ionic liquids (ILs) suitable as diathermic fluids, were studied. Immersion tests were performed at 220 1C (the working temperature in such plants) for 10 days. The corrosion morphologies of the steels were investigated by scanning electron microscopy coupled with energy dispersive X-ray (EDX) microanalysis and the content of metals in the solution were detected via ICP-OES. The tests showed that the m… Show more

“…Ionic liquids (ILs)-a group of salts, which are liquid at ambient temperature (less than 100°C) and are considered as the potential replacement of the currently used working fluid [3][4][5][6][7][8]. ILs have several excellent physical and chemical properties including high thermal stability, negligible vapor pressure and volatility, exposure to air and moisture stability, low melting point, wide electrochemical window, nonflammability, high ionic conductivities, high solvating capability, corrosion resistance to plastics and carbon steels [9][10][11][12][13][14][15][16][17][18].…”

“…Many reasons justify the limited exploitation of the research results in commercial systems (e.g. higher corrosion rates 24 and stability under room condition). Traditional solvents as water are often cheaper and abundant.…”

“…Gracias a la estabilidad térmica y las propiedades térmicas (capacidad calorífica) mencionadas, los líquidos iónicos pueden ser utilizados como fluidos térmicos que absorben la energía solar y la transforman en calor, pudiendo llegar a ser más eficientes que los fluidos térmicos convencionales [32,[149][150][151].…”

“…Respecto a la corrosión, hay que tener en cuenta tres aspectos: la corrosión causada por los ILs en la superficie en la que se encuentran, la oxidación del propio IL y el desarrollo de reacciones triboquímicas en las superficies de deslizamiento cuando se usan como lubricantes [22,46,47,151,[164][165][166][167][168][169].…”
