Chemical Engineering

Main features of the chemical plants (2 ECTS) (chemical manufacturing processes, industrial sites, utilities, sources of risk and prevention criteria, overview of the main equipment, documentation and graphical representations) Storage of gases, liquids and solids (1 ECTS) (types of storage equipment, tanks design) Piping (1 ECTS) (piping and accessories, valves, pumps and compressor, design criteria) Heat Exchange Operations (2 ECTS) (enthalpy balances and heat exchange coefficients, construction characteristics of heat exchange equipment, sizing of shell and tube heat exchangers)

It is essential the knowledge of thermodynamics prior to the course attendance; it is also important to acquire knowledge of transport phenomena during the course attendance.

Course attendance is not mandatory.

The exam consists in both a written and an oral test. The written test consists of a design or rating exercise: the evaluation will be based on both the calculus results and their presentation, that has to be clear, effective and concise. To pass the oral test, the student must demonstrate to have acquired a sufficient knowledge of the course topics. A knowledge of a higher level and the ability to apply the acquired knowledge to solve practical problems will lead to an evaluation mark up to 27/30. A better evaluation, up to 30/30, will be achieved when the student is also able to expose clearly and concisely the acquired knowledge. 30 cum laude will be assigned to the students who demonstrate to have acquired an excellent knowledge of the course topics, to expose it clearly and concisely, to be able to solve practical problem and to extrapolate the acquired skills.

Course attendance is not mandatory. Lessons are organized in lectures, numerical applications and case studies.
