**Chemical and Biochemical Engineering**

4 ECTS; 1º Ano, 1º Semestre, 15,0 T + 30,0 TP

**Lecturer**

- Dina Maria Ribeiro Mateus

**Prerequisites**

Basics of mathematics and chemistry.

**Objectives**

Students should be aware of the significance of chemical and biological industries to a sustainable development; identify variables and classify different process types; interpret manufacturing diagrams and flowsheets.

**Program**

This course unit?s purpose is to provide:

(a) an integrated and strategic overview of the chemical/biological process engineering applied to the major industrial sectors and their integration on the modern society;

(b) an introduction to the chemical engineering calculations;

(c) definitions, illustrative measurement techniques and methods of calculating variables that characterize the operation of processes.

After completing this course the students should be able to:

(a) understanding the significance of chemical/biological industries to a sustainable development;

(b) convert units using; identify the number of significant figures; explain the concept of dimensional homogeneity of equations; use linear interpolation; fitting linear and nonlinear data; use scientific calculators and spreadsheets for the representation and analysis of data;

(c) identify variables and classify different types of processes; interpret manufacturing diagrams and their corresponding flow sheets.
