About the Speaker
Stefania Moioli is research fellow of Unit Operation of Chemical Plants at Politecnico di Milano. She is member of the Group on Advanced Separation Processes & Gas Processing (GASP). Her research interests cover thermodynamics, kinetic modeling and steady state/dynamic process simulation, in particular applied to the purification of acid gases from different gaseous streams (flue gases from power plants, natural gas, syngas, …).
Gas treatment processes are becoming increasingly important also as environmental tools for controlling the composition of several gaseous streams. They can be sources of carbon dioxide whose presence is strictly limited by environmental regulations or by the commercial specifications of the final product.
Absorption by chemical solvents is one of the most effective methods for acid gas removal: alkanolamine scrubbing is widely used for gas treating and can be applied to different types of gas (flue gases from power plants, natural gas, syngas, …). However, one of the major drawbacks is the high energy consumption for solvent regeneration, which justifies the research effort to develop more effective and possibly environmentally friendly processes for the removal of CO2. Alternative processes under study include the chemical absorption process by amino acid solvents for the purification of flue gases and the dual-pressure low-temperature distillation for the sweetening of natural gas. The seminar will be focused on the analysis of the features and the simulation of these two different processes.
