CHEMICAL ENGINEERING DEPARTMENT SYLLABUS, TEXTBOOKS, REFERENCE BOOKS, IT IS APPLICABLE FOR ALL STUDENTS ADMITTED IN THE YEAR 2011 2012-2013 (ANNA UNIVERSITY CHENNAI,TRICHY,MADURAI,TIRUNELVELI,COIMBATORE), 2008 REGULATION OF ANNA UNIVERSITY CHENNAI AND STUDENTS ADMITTED IN ANNA UNIVERSITY CHENNAI DURING 2009
CH2305 MASS TRANSFER I L T P C
3 0 0 3
AIM
To impart knowledge on how certain substances undergo the change in composition,
change in phases and exhibit the properties according to the changed environment.
OBJECTIVES
Students develop a sound knowledge on the types of Mass Transfer thro’ a driving
force in the same fashion as temperature differences as driving force for heat
transfer. The students shall have an elementary knowledge on fluid flow, heat
transfer and stoichiometry.
45
UNIT I DIFFUSION 8
Molecular and eddy diffusion in gases and liquids, steady state diffusion under stagnant
and laminar flow conditions Diffusivity measurement and prediction, multicomponent
diffusion, diffusion in solids and its applications.
UNIT II MASS TRANSFER COEFFICIENTS 12
Concept of mass transfer coefficients, mass transfer under laminar and turbulent flow
past solids, boundary layers, mass transfer at fluids surfaces correlation of mass transfer
coefficients, JD, HTU, and NTU concepts, theories of mass transfer and their
applications, interphase mass transfer and over all mass transfer coefficients in binary
and multicomponent systems, application to gas-liquid and liquid-liquid systems.
UNIT III HUMIDIFICATION AND AIR CONDITIONING 8
Basic concepts, psychrometric chart construction, Humidification and dehumidification
operations, and design calculations, cooling tower principle and operation, types of
equipment, design calculation.
UNIT IV DRYING 9
Theory and mechanism of drying, drying characteristics of materials, batch and
continuous drying, calculation for continuous drying, drying equipment, design and
performance of various drying equipments.
UNIT V CRYSTALLISATION 8
Nuclei formation and crystal growth, theory of crystallization, growth coefficients and the
factors affecting these in crystallization, batch and continuous industrial crystallizers,
principle of design of equipment.
TOTAL : 45 PERIODS
