EQUIPMENT DESIGN FOR CHEMICAL INDUSTRY

Preliminary information and basic techniques are provided for the mechanical design of components of industrial plants, in particular in the field of chemical and petrochemical plants.

Topics related to the behavior of materials under mechanical and / or thermal loads under static and dynamic conditions and design of simple mechanical components will be dealt with.

The course will be divided into two modules, respectively 61 hours (Module A) and 30 hours (Module B), held by Prof. Giudice. Both modules will consist of:

Frontal lessons.

Exercises on the topics of the course.

Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus.

Module A:

Concepts of elasticity theory, Hooke's law, concepts of stress and strain,

Equilibrium of a solid body, internal actions and constraint reactions. Isostatic and hyperstatic. Axial and tangential forces.

Mass and area geometry.

Concepts of tensile / compressive, bending, torsion and shear stresses. The stress tensor. Principal and ideal stresses.

Bending beams, methods for determining stresses and displacements. Principle of virtual works and singularity functions.

Euler's critical load.

Fatigue of materials.

Thermal stresses. Viscoelasticity. Creep and relaxation.

Introduction to fracture mechanics.

Axles and transmission shafts.

Module B:

Pressure vessels (Towler & Sinnott)
Piping systems (Towler & Sinnott, teacher notes)
Heat-transfer equipment (Towler & Sinnott, teacher notes)
Approaches to materials selection (Ashby)
