Mass transfer - Labwork - 3FME3024

Goal(s)

Learning outcomes :

• to apply Material Transfer methods to the study of materials: filtration membrane, lignocellulosic materials.
• To measure diffusion coefficients.
• To know the functioning and properties of an ion exchange resin in batch and continuous reactor
• To measure the characteristics of the resin studied (exchange capacity, specific surface area, exchange constant,...)
• To measure material transfer coefficients between resin and fluid phase in the reactors studied

Content(s)

Practical work cycle includes 4 sessions:

• Quasi-stationary mass transfer through a membrane: determination of the diffusivity of a solute through a membrane.
• Desorption kinetics from wood chips: effect of tortuosity in the radial and longitudinal directions.
• Mass transfer and exchange in a resin bed: characterization of the resin (exchange capacity, densities, equilibrium constant, ...); study of continuous operation: piercing curve, global mass transfer coefficient and HUET.
• to put into practice the knowledge acquired in the courses the courses: mass transfer and mass exchanges (mass balance, diffusion, convection, dimensionless numbers, height of unit transfer,...);
• to put into practice the knowledge acquired on flow in porous media (energy balance,...);
• to characterize an ion exchange resin (exchange capacity, specific surface, exchange constant ,...)
• to write and structure a pratical work report that includes an analysis of the results;
• to hexperiment with care (preparation of solutions, dosages, space of measurement organization ,...).
• To illustrate also course on flow into porous media (PW on resin bed).
