Recommended Prerequisites

Introduction to Chemical Engineering, Chemical Thermodynamics, Transport Phenomena I, Mass and Energy Balances, The student must be enrolled in Transport Phenomena II.

Teaching Methods

This curricular unit has a dominant component of experimental nature and another complementary of theoretical-practical nature. The first allows the execution of 6-7 laboratorial works from the list in 3.5. The second component allows the discussion of the results of the works, between the teacher and the students, completing the learning cycle.

Students work in groups, being the experimental works to be performed by each group selected to cover all foreseen areas. The frequency of execution of the works is biweekly, and the discussion of each work will be done in the week’s interval.

Learning Outcomes

This curricular unit aims to spark interest in the practice of Chemical Engineering and provide the consolidation/integration of knowledge from disciplines in the same academic year. These goals can be reached through the implementation and results analysis of various laboratorial works that illustrate specific problems of base areas of Chemical Engineering: Chemical Thermodynamics and Transport Phenomena.

Students acquire specific skills at the level of experimental work such as: selection/study of necessary information; planning/conducting experiments; treatment/framing of results; familiarity with experimental methods; behavior in the laboratory.

They also develop generic skills: instrumental - analysis and synthesis, organization and planning, problems solving, oral and written communication, information management; personal - teamwork, critical thinking; and systemic - autonomous learning, application of theoretical knowledge.
