The lectures give an up-to date and essential knowledge on compositions, properties and applications of crude oils and hydrocarbon fractions obtained through refining processes. Chemical, technological and economical aspects of the industrial processes involved in the oil refining and hydrocarbon fraction conversion are considered together with computing methods suitable to evaluate the influence of the process variables in the petroleum refining by distillation.

Chemical, technological and economical aspects of the industrial processes involved in the oil refining and hydrocarbon fraction conversion are considered together with computing methods suitable to evaluate the influence of the process variables in the petroleum refining by distillation.
Aim of the course is to provide a basic knowledge about the chemical and technological evaluation of crude oils and its fractions in order to be used as raw materials for industrial processes either for fuels or chemicals production. The student has to learn about the analytical, scientific and technological methods useful for the oil characterization and must acquire a clear picture of the refinery processes involved in the transformation of petroleum into commercial hydrocarbon mixtures. At the end of the course, it is expected that the student is able to plan a full characterization of a crude oil, either for economical or technological purposes, and has the capacity to evaluate the suitability of a hydrocarbons mixture to be used as a raw material for fuels production or for chemical transformations through petrochemical processes.

Lectures are integrated with numerical exercises: students are asked to solve simple problems connected with the topics of the lesson. A cycle of computing practice is developed in a computing laboratory (LAIB) to design distillation equipments through a process simulator (Aspen Plus). Aim of the practice is to become friendly with computing software suitable to design equipments in the field of petroleum processing. The distillation of a two component liquid mixture and a crude oil at atmospheric pressure are simulated with the goal to optimize the process variables and to reach designed properties of the products. Evaluation of the simulation ability will be performed by analysis of a written report on the obtained results.

Before each lecture, related texts and exercises will be available on the course site of the web. Besides the subject explained in the lesson, will be stored on the site also chapters of technical books useful for a best comprehension and deepening of the lesson topics. Materials requiring periodic updating will be available before the end of the course.
