Learning outcomes
This course will enable students to understand membrane separation mechanisms and solve membrane-based separation problems by acquiring in-depth knowledge in the area of transport models, membrane permeability, membrane types and modules, membrane design and preparation.
Course contents
Introduction
Fundamentals on separation processes and membrane technologies. Basic definitions. Membranes and membrane processes classification. Preliminary description of membrane processes.
Membranes and membrane separation modules
Brief description of the main polymeric and ceramic membranes Materials and functional characterizazion of membranes. Schematic of membrane modules: tubular, spiral wound, hollow fibers, plate&frame. Estimate of mass transfer coefficients.
Main membrane processes
Analysis of Reverse Osmosis, Nanofiltration, Ultrafiltration, Microfiltration, Pervaporation and Gas Separation processes. Transport phenomena and thermodynamics in membrane processes: osmotic pressure, hydraulic permeability, gas permeability, solution-diffusion model. Problem of concentration polarization and the role of operative conditions on process performances.
Membranes characterization
Experimental data for UF, RO and NF, pervaporation and gas separation. Hydraulic permeability and rejection factor. Gas permeability and selectivity - Robeson plot. Thermodynamics and trasport properties in polymeric materials. Solubility and diffusivity coefficient.
Membrane modeules design
Analysis of process goals and thermodynamic constraints. From membrane characterization to modules design. Single step and multiple steps membrane separation. Thermodynamic analysis of membrane sepration processes. Economics: main cost items of a plant (capital, operative, energy, maintenance)
Case studies
hydrogen recovery, air fractionation, bio-gas upgrading to bio-methane, VOC removal from gaseous streams, pre-combustion and post-combustion CO2 capture.
