OVERVIEW

Chemical reactors are the core of almost all industrial production processes. The correct choice of a chemical reactor, which operates in the most efficient and safe way, is often the key to the economic success of a production plant. The field of knowledge related to chemical reactors is the one that most characterizes a chemical engineer with respect to all other types of engineer, and it is presented in this course.

AIMS AND CONTENT

LEARNING OUTCOMES

The aim of the course is to enable the student to apply the basic concepts of chemical engineering (mass balances, kinetic laws, stoichiometry, energy balances, etc.) to the design of homogeneous chemical reactors.

AIMS AND LEARNING OUTCOMES

Active participation in the proposed training activities will allow the student to:

  • Write the material balance equations for an ideal reactor
  • Properly design an ideal reactor once the kinetic law is known
  • Determine the kinetic law of a chemical reaction from the analysis of laboratory tests
  • Calculate the selectivity for the case of multiple reactions in ideal reactors
  • Set the energy balance equation in chemical reactors

PREREQUISITES

Although formally no prerequisites are required, it is strongly recommended to follow the course only after the math exams (I and II) have been successufly passed

Teaching methods

Teaching is delivered by frontal lectures in the classroom. 35 hours will be devoted to the presentation of theoretical contents while 25 hours to the solution of problems and numerical exercises. Transversal skills will be acquired through the solution of numerical exercises to be carried out in groups with the use of commercial software packages.

SYLLABUS/CONTENT

  • Definition of reaction rate, material balance for a chemical reactor. Definition of conversion degree, dsign of ideal chemical reactors. (15 h)
  • The kinetic laws. Stoichiometric tables for the various types of reactors. (10 h)
  • Chemical reactors in unstready-state regime. (5 h)
  • Determination of the kinetic law from laboratory data: integral method, differential method, initial velocity method. (10 h)
  • Multiple reactions in chemical reactors (5 h)
  • Non-isothermal reactors in steady-state and dynamic regime. (10 h)
  • Residence times distribution in chemical reactors. Models for non-ideal chemical reactors. (5 h)

Teaching methods

Teaching is delivered by frontal lectures in the classroom. 35 hours will be devoted to the presentation of theoretical contents while 25 hours to the solution of problems and numerical exercises. Transversal skills will be acquired through the solution of numerical exercises to be carried out in groups with the use of commercial software packages.

LESSONS START

Teaching will start the week of March 4th, 2019. 

EXAMS

Exam description

The final assessment test consists in the solution of a written numerical problem.Students who have successfully passed the numerical tests proposed during the semester will be exempted from the final assessment test.

Assessment methods

The tests and the final written exam will focus on the numerical design of an ideal chemical reactor. Both the correct setting of the problem and the correctness of the numerical calculations will be taken into consideration in the evaluation.
