EV4018 Environmental Reaction Engineering Syllabus:
EV4018 Environmental Reaction Engineering Syllabus – Anna University PG Syllabus Regulation 2021
OBJECTIVES:
To gain an understanding of the fundamentals of chemical reaction engineering with a focus on chemical reaction rates and reaction mechanisms. The course will cover mole balances, rate laws, chemical kinetics, and reactor design. These principles can be applied to any environmental system where chemical transformations must be described.
UNIT I PRINCIPLES OF REACTION ENGINEERING
Classification of reactions, reaction rate, variables affecting reaction rate, speed of chemical reactions. Reaction engineering principles of chemical treatment – chemical reactions in major treatment technologies, incineration, selective catalytic reduction. Wet- gas scrubbing – H2S
UNIT II KINETICS OF HOMOGENOUS REACTIONS
Simple reactor types, the rate equation, concentration dependent term of rate equation. Molecularity and order of reaction. Rate constant k, representation of an elementary and nonelementary reaction. Kinetic models for nonelementary reactions. Testing kinetic models. Temperature dependent term of rate equations from Arrhenius theory and comparison with collision and transition state theory. Activation energy and temperature dependency.
UNIT III REACTOR ANALYSIS
Reactor concepts, ideal reactors, reaction rate measurements, sequencing batch reactor, reactors in series and reactors in recycle. non-ideal reactor behaviour, RTD analysis
UNIT IV MASS TRANSFER AND ITS APPLICATIONS
Principles of diffusion and mass transfer between phases, gas absorption, humidification operations, leaching and extraction, drying of solids, fixed-bed separation, membrane separation process adsorption.
UNIT V BIOLOGICAL REACTION ENGINEERING
Kinetics of cell growth and enzymes. cell growth kinetics; substrate uptake and product formation in microbial growth; enzyme kinetics, Michaelis-Menten rate form.-biological kinetics, aerobic processes-anaerobic processes – anaerobic digestion, anaerobic filters, Up flow anaerobic sludge blanket reactor. bio concentration, bioaccumulation, bio magnification, bioassay, bio monitoring. bio scrubbers, bio trickling filters and their applications. vermi technology, methane production, root zone treatment, membrane technology.
