Course objectives

The aim of the course is to acquaint students with technological processes of refining of petroleum and natural gas for the production of fuels and lubricants and selected petrochemicals, as well as the processes of conversion of petrochemicals in the intermediate and/or final products with respect to economic, environmental and safety conditions in industrial production.

Course enrolment requirements and entry competences required for the course

Enrolled in or passed the course Exercises in Technological processes in organic industry

Learning outcomes expected at the level of the course (4 to 10 learning outcomes)

After the successfully passed exam student should be able to:
- explain the specifics of the organic chemical industry
- describe the of primary and secondary processes of petroleum processing
- describe the processes of petroleum products refining
- specify the basic petroleum products and their characteristics
- describe technological processes of conversion of selected petrochemicals in the intermediates and / or products
- sketch diagrams of selected technological processes
- synthesize chemical engineering knowledge on the examples of industrial processes in modern organic chemical industry

Course content broken down in detail by weekly class schedule (syllabus)

1st week: Introduction. Characteristics and significance of the organic chemical industry. The development of the organic chemical industry
2nd week: Petrochemical raw materials and products. World production and consumption of oil and natural gas; an estimation of remaining oil reserves
3rd week: Classification and characteristics of chemical reactions and processes; Chemical reactors; optimization of chemical processes; economy and ecology of chemical processes
4th week: Petroleum: energent, petrochemicals source. Origin, exploration, drilling and transportation of petroleum. Chemical composition and properties of petroleum.
5th week: Processes and products of petroleum processing. The primary petroleum refining processes: distillation processes
Written test (first)
6th week: The secondary petroleum refining processes: thermal processes - cracking, visbreaking, coking;
7th week: Catalytic processes - cracking, hydrocracking, reforming, isomerization, oligomerization, alkylation)
8th week: Refining processes of petroleum fractions: specially treating of the fuels and lubricating oils (sweeting, deasphalting, dewaxing, furfural extraction, hydrofining process).
9th week: Oxidation processes-removal of sulfur compounds; Bitumen production.
10th week: The basic petroleum products.
Written test (second)
11th week: Natural gas: exploration and processing
12th week: Processes of production of components for organic synthesis: Production of alkanes. Methane. Syngas, production and applications. Methanol. Formaldehyde. Acetic acid. Fisher-Tropsch synthesis.
13th week: Production of alkenes: pyrolysis of hydrocarbons. Chemicals from C4 and C5 fraction. Oligomerization of ethylene. Uses of ethylene: acetaldehyde, ethylene oxide, ethylene glycol.
14th week: Uses of C4 hydrocarbons. Acetylene. Production of aromatic hydrocarbons. Separation BTX hydrocarbons. Uses of the aromatic hydrocarbons: phenol, styrene.
15th week: Polymers and polymerization processes (chain and step polymerization reactions). Production of polyethylene.
Written test (third)

Grading and evaluating student work in class and at the final exam

The complete exam can be passed through three partial tests during semester.
Attendance on lectures, A1(successfulness =70 -100 %), share in grade, k1 =0,10
1st test, A2 (successfulness =60 -100 %), share in grade, k3 =0,30
2nd test, A3 (successfulness =60 -100 %), share in grade, k4 =0,30
3rd test, A4 (successfulness =60 -100 %), share in grade, k4 =0,30
GRADE (%) = 0,10A1+0,30A2 + 0,30A3+ 0,30A4
Students who did not take or pass partial tests have to attend to written and oral exam in the regular exam periods.
Activitie A1 is evaluated in the same way as indicated above.
Written exam, A5 (successfulness =60 -100 %), share in grade, k5 =0,45
Oral exam, A6 (successfulness =60 -100 %), share in grade, k6 =0,45
GRADE (%) = 0,10A1+ 0,45A5 + 0,45A6
FINAL GRADE: successful (60% – 70 %), good (71% – 80 %), very good (81% – 90 %), excellent (91% – 100 %).
In the case that student passed only one or two tests during continuous evaluation, he/she have to attend to written and oral exam in the regular exam periods. The passed test will be recognized by the end of the academic year as a part of the written exam.
