The final essay consists of two parts:
1) A series of laboratory tests, related to different aspects of chemical engineering. On these tests the students must prepare written reports, calibrated to develop the different skills in interpretation and communication that are required by engineering (detailed analysis of the problem, synthesis, processing data, ...).
2) A brief oral presentation prepared under the guidance of a tutor, in which one of the subjects studied in the chemical engineering courses is analysed in greater detail. Before the presentation, the student must submit a written summary (two pages) on the subject.
