CY6251 ENGINEERING CHEMISTRY-II SYLLABUS (REGULATION 2013) ANNA UNIVERSITY
UNIT 1: WATER TECHNOLOGY
(CY6251) Introduction to boiler feed water – requirements – formation of deposits in steam boilers and heat exchangers – disadvantages (wastage of fuels, decrease in efficiency, boiler explosion). Prevention of scale formation – softening of hard water -external treatment zeolite and demineralization – internal treatment. Boiler compounds (phosphate, calgon, carbonate, colloidal) – caustic embrittlement-boiler corrosion-priming and foaming- desalination of brackish water –reverse osmosis.
UNIT 2: ELECTROCHEMISTRY AND CORROSION
Electrochemical cell – redox reaction, electrode potential- origin of electrode potential. Oxidation potential- reduction potential, measurement and applications – electrochemical series and its significance. Nernst equation (derivation and problems). Corrosion- causes- factors- types- chemical, electrochemical corrosion (galvanic, differential aeration), corrosion control – material selection and design aspects – electrochemical protection – sacrificial anode method and impressed current cathodic method. Paints- constituents and function. Electroplating of Copper and electroless plating of nickel.
UNIT 3: ENERGY SOURCES
Introduction- nuclear energy- nuclear fission- controlled nuclear fission- nuclear fusion- differences between nuclear fission and fusion- nuclear chain reactions- nuclear reactor power generator- classification of nuclear reactor- light water reactor- breeder reactor- solar energy conversion- solar cells- wind energy. Batteries and fuel cells:Types of batteries- alkaline battery- lead storage battery- nickel-cadmium battery- lithium battery- fuel cell H2 -O2 fuel cell- applications.
UNIT 4: ENGINEERING MATERIALS
Abrasives: definition, classification or types, grinding wheel, abrasive paper and cloth. Refractories: definition, characteristics, classification, properties – refractoriness and RUL, dimensional stability, thermal spalling, thermal expansion, porosity; Manufacture of alumina,
magnesite and silicon carbide, Portland cement- manufacture and properties – setting and hardening of cement, special cement- waterproof and white cement–properties and uses. Glass- manufacture, types, properties and uses.
UNIT 5: FUELS AND COMBUSTION
Fuel: Introduction- classification of fuels- calorific value- higher and lower calorific values- coal- analysis of coal (proximate and ultimate)- carbonization- manufacture of metallurgical coke (Otto Hoffmann method) – petroleum- manufacture of synthetic petrol (Bergius process)- knocking-
octane number – diesel oil- cetane number – natural gas- compressed natural gas(CNG)- liquefied petroleum gases(LPG)- producer gas- water gas. Power alcohol and bio diesel. Combustion of fuels: introduction- theoretical calculation of calorific value- calculation of stoichiometry of fuel and air ratio- ignition temperature- explosive range – flue gas analysis (ORSAT Method).
