Chemical Engineering Laboratories I

Recommended Prerequisites

Introduction to Chemical and Biochemical Engineering, Data Processing, Analytical Chemistry, Chemical Thermodynamics,  Fluid Dynamics, Mass and Energy Balances. The student must be enrolled in Heat Transfer.

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 3.3.5. 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 of 3, 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 of the 1st and 2nd years of the course. These goals can be reached through the implementation and analysis of several laboratorial works representative of specific problems of base areas of Chemical Engineering: Analytical Chemistry, Chemical Thermodynamics, Fluid Dynamics and Heat Transfer.

Students acquire specific skills at the experimental level: selection of information; planning/conducting experiments; treatment/framing of results; familiarity with experimental and statistical methods; behavior and safety 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).
