Objetivos

The curricular unit has the main goal that student acquires knowledge and competences in the areas of applied thermodynamic to Petroleum Tecnologies.

It is essential that the students understand and predict physical properties of ideal and real gases, knowing how to apply the three laws of thermodynamics to reactions, allowing them to predict and calculate heat and/or work exchanges, entropy variations and spontaneity of the processes.

The student must be able to interpret phase diagram of pure substance, understanding the meaning of triple and critic points, and also to interpret different phase diagrams for mixtures, establishing the basis for several industrial separation process.

It is also necessary that student understand the differences between ideal and real liquid mixtures and the importance of the activity coefficients concept, allowing them to control the variables that affect the equilibrium.

Métodos de ensino e atividades de aprendizagem

In theoretical classes fundamental concepts are exposed, using audio-visual techniques. Illustrative applications of these concepts are solved, stimulating rational thinking and fostering a more critical spirit.

In TP classes, students solve individually and independently the application exercises proposed. It is worth to mention that there is a time for tutorial orientation (as part of the doubt schedule), which is meant for the students to solve extra exercises or other assignments/projects.

In the same semester there is a laboratory curricular unit associated (Laboratory II) in which the students performs several experimental works that exemplifies the thermodynamics principles applications.
