Technologies and Chemical Processes

Objectives

The goal is for students to formulate and solve mass and energy balances in chemical processes. Basic concepts of thermodynamics, unit operations, kinetics, and dynamics of processes are also introduced. Some technologies and processes used in the chemical industry are addressed.

Teaching method

The teaching method consists of theoretical-practical classes, where successive topics of the discipline''s program will be covered. The exposition of the subject matter is accompanied by the presentation of practical examples, allowing the consolidation of knowledge and encouraging the critical participation of students. After introducing the concepts, various practical problems are solved, requiring the application of the learned knowledge. Learning is complemented by presenting a seminar on an industrial chemical process.

Evaluation method

Evaluation:

  • 2 tests and 1 seminar
  • the final grade is given by 35% 1st test (miniminum grade 9.5) + 45% 2nd test + 20% seminar
  • The 2nd test and the seminar have no minimum grade
  • Revision of tests requested by the student may result in an alteration of the mark if an error in correction or quotation is found and as such may result in an increase or decrease of the mark.
  • The seminars are mandatory for students who do continuous evaluation.
  • Students who choose to take only the exam can also take a seminar, with a score of 80% grade of exam + 20% grade of seminar.
