Processos em Engenharia com Solventes Alternativos
1. Acquire knowledge on alternative solvents, their properties, phase diagrams with other relevant compounds and uses.
2. Recognize important properties of solvents and how to manipulate their chemical structure in order to obtain desired chemical properties.
3. Integrate and interpret the different roles of one solvent in different parts of the same process.
4. Use appropriate software to predict relevant process properties of solvents and interpret the results.
5. Identify, in a scientific way, the underlying physical phenomena to the problem in question.
6. Re-formulate scientific solvency problems taking into account process efficiency and economics as well as other environmental and human health issues.
7. Develop critical thinking, question asking, problem solving and decision making in the context of solvent selection.
8. Perform critical reading and assessing the literature for greenness and sustainability.9. Students will participate in discussion exercises and perform critical green audit of papers recently published in leading journals as well as current technological advances in the field.
