	CHIM0083-2   Chemical Engineering (Unit Physical Operations and Non-Specific Aspects of Apparatuses) Duration :   45h Th, 45h Pr Credits/ECTS :   Master in Chemical Engineering and Materrial Sciences, in-depth approach, 1st year First semester 8 Master in Chemical Engineering and Materrial Sciences, in-depth approach, 2nd year First semester 8 Master in Chemical and Material Sciences, specialized approach, 1st year First semester 8 Holder(s) :   Michel Crine Language :   French language Course contents :   Introduction to the concept of unit operations. Heat and mass balance equations. Concept of characteristic scale. Application to the following physical unit operations: Gas-liquide absortpion-desorption : Different configurations of gas-liquid contactors (co- and counter-current, operating line). Stage contactor (theoretical stage, plate efficiency), continuous contactor (number of transfer units, height of a transfer unit). Relation between number of theoretical stages and number of transfer units. Heat echangers : Different configurations. Local heat transfer kinetics. Counter-current heat exchanger. Number of (thermal) transfer units. Efficiency of a heat exchanger. Design methods : DTLM and NTU-epsilon. Distillation : Different configurations : mono- and multi-stage distillation, continuous and discontinuous. Thermodynamic liquid-vapour equilibrium. Coupling between heat and mass balance. Lewis-Sorel equation, McCabe-Thiele and Pochan-Savarit methods. Direct thermal contactors : Applications: gas washing, water cooling, air conditionning. Steam-water equilibrium. Psychrometric diagram, local heat and mass transfer kinetics. Wet bulb temperature. Global heat and mass balances. Prerequisites :   Course of Introduction to Chemical Engineering CHIM0022-2. Workshops :   Practical work : Problems resolution. Laboratories : Distillation column, plate column, packing column and heat exchanger. Organization :   The course is scheduled for the first quadrimester. The course schedule is available on the Internet site of the applied sciences faculty. (http://www.facsa.ulg.ac.be/) Assessment :   Oral examination in January on the content of the lectures. Written examination of exercises in January. Laboratory reports.
