Process Integration and Intensification

Recommended Prerequisites

Chemical Thermodynamics; Mass and Energy Balances; Programming and Numerical Methods; Heat Transfer; Introduction to Reaction Engineering; Chemical Reactors; Solid-Liquid Operations; Mass Transfer; Modeling, Simulation and Optimization; Separation Processes; Industrial Effluents and Environment; Process Modeling and Supervision; Advanced Separation Processes; Energy and Biofuels

Teaching Methods

Classes are used to present the basic concepts, definitions, formulations and illustrative examples. These concepts are later practiced by the students during the solution of a set of tasks, in groups of 2-3 people.

The final grade involves two components: a) solution of a number of tasks during the semester (30%); b) final exam (70%). Students need to obtain a minimal classification of 8/20 in the final exam. The final exam will involve questions that require the demonstration of theoretical and practical skills and competences acquired during the semester.

Learning Outcomes

This curricular unit will help the students in developing capabilities of applying mathematical techniques (graphical and numerical) in the analysis and synthesis of heat and mass transfer networks, and in specific application problems in the area of process intensification. It is intended that the students master the concepts of maximum energy recovery networks, and become able to apply the concept of pinch locations in the determination of the most favourable solutions. The students will also develop their capabilities of knowledge integration in the areas of transfer, transformation and separation processes. Other capabilities also improved: process synthesis and critical thinking in the selection of alternative process solutions, capability of solving problems that require the integration of knowledge from various other curricular units, and capability of team work.
