Taschenbuch. Condición: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - A squid by-product gelatinous protein polymer (SBP) has been extracted, characterized and examined as eco-friendly inhibitor for carbon steel in 0.5 M H2SO4 media by weight loss, electrochemical techniques. It was found that the SBP acts as a good corrosion inhibitor. The inhibition efficiency increases with increasing inhibitor concentration, but the temperature has hardly affected on the inhibition efficiency of SBP. Thermodynamic data clearly show that the adsorption mechanism of SBP on the carbon steel surface in 0.5 M H2SO4 solution is mainly physical adsorption. Moreover, the adsorption of the SBP molecules was found follows a Langmuir adsorption isotherm. Results of potentiodynamic polarization measurements revealed that the SBP acts as mixed-type inhibitor. Data obtained from EIS studies were analyzed to model inhibition process through appropriate equivalent circuit model. Theoretical parameters derived from quantum chemical calculations as well as binding energy derived from molecular dynamics simulations studies adequately corroborate the trend of experimental inhibition efficiencies of the studied inhibitors. …

Taschenbuch. Condición: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - In conventional heat transfer equipment heat is exchanged between two fluids which are physically separated by a solid interface. Typical examples of such equipment can be found in devices as varied as air conditioning units, aircraft and motor-vehicle engines, chemical processing plant, domestic refrigerators and radiators, electrical and electroni equipment, heat rejection systems in space vehicles, nuclear fuel storage tanks, and steam turbine installations.In these devices the separating interface invariably comprises a primary surface, such as a plane wall or a cylindrical tube, with slender metallic strips, referred to as extended surfaces, attached to one side. Consequently, such devices are classified as extended surface heat exchangers. The extended surfaces offer a convenient means of achieving a large heat transfer surface area without the use of excessive amounts of primary surface, and are mainly employed in situations in which there is a particular emphasis on minimising either the size or the weight of thp. heat transfer equipment. Many types of industrial plant heat exchangers are affected by corrosion , including condensers, feedwater heaters.…
