29931 - Fundamentals of Industrial Chemistry

Learning outcomes

The student,by the analysis of some of the most important productive lines in process industry,will be able to understand the plant,economical and environmental reasons that have determined the realized solutions. By the help of the earned methodology he wil be able, in other situation, to define the operations and the conditions to obtain the desired results.

Teaching methods

The different production lines will be proposed and discussed. During practice hours mass and energy balances of the most important production lines will be carried out.

Assessment methods

First a written test consisting in the calculation of flow rates, temperatires and thermal fluxes for streams and apparatuses of a plant section.
After an oral test consisting in the discussion of productive lines proposed during the lectures.

Teaching tools

Overhead projector
