Petroleum Refinery Engineering and Petrochemical TechnologyCOVENANT UNIVERSITY COURSE COMPACT FOR 2014/2015 ACADEMIC SESSION College: Engineering Department: Chemical Engineering Programme: Chemical Engineering Course Code: CHE 528 Course Title: Petroleum Refining Engineering/Petrochemical Technology Units: 3 Course Lecturers: Dr. Anawe P.A.L. and Prof. Denloye Semester: Omega Time: Location: P28 (Chemical/Petroleum Engineering Building) a. Brief Overview of course Petroleum Refining is the physical, thermal and chemical separation of crude oil into its major distillation fractions which are then further processed through a series of separation and conversion steps into finished petroleum products. Crude oil is a naturally occurring, flammable liquid found in rock formations in the earth consisting of a complex mixture of hydrocarbons of various molecular weights, other organic compounds plus some inorganic compounds – O, N, S, metals Ni, V, etc. The quality of the crude oil dictates the level of processing and reprocessing necessary to achieve the optional mix of product output. Brief talk on petroleum chemistry to enable proper understanding of the various conversion processes. b. Course Objectives/Goals During and at the end of the course, students should be able to: 1. The importance of petroleum/gas to modern civilization 2. The various types of crude oils light/heavy and how they are processed into economically useful products; 3. Details of various catalysts used in refining processes; 4. Characteristics of various finished products 5. Handling, storage, transportation and usage of some; 6. Details of hazards and the necessary measures to be taken to avert danger and keep safe c. Methods of Lecture Delivery/Teaching Aids * Visual Aids (use of Power Point slides, Lecture template-handouts) * Framed pictures of real refineries – meaning 1m2 * Sample of bottled crude oil * Audiovisual Aids * Crude oil types for different refinery configurations * Introduction to refinery equipment refraction rating coloms, heat exchangers, dehydrators, desalters, storage facilities for crudes and finished product. Flow sheets, plates Atm distillation units, vacuum units, base oils (different groups) catalyst cracking, catalyst reforming, hydro cracking, alkylation product blending and usage, octane Number, cetane Number. Gasoline properties and blending, JET fuel (jet-A1), Gas distillate fuels: heating oil, lubricants and greases, asphalts (bitumen). * Visbreaking, residual processes polities of oil + gas processing OPEC, APPA, etc. petrochemical raw materials from the refeneries, LPGas – propane, butane, natural gas, methane, propane, butane, ethylene, benzene, zylene, toluene, tec, LDPE HDPE, LAB, Carbon black. d. Tutorials Extra lectures with special questions to widen the horizon of the student. Advanced Refinery Technology such as ultra-low NOx burners and new generation catalysts, has enabled the production of increasing cleaner fuels while generating less and facilities, etc. e. Structure of the Programme/Method of Grading Assignment/term paper - 10% Test - 20% Final Exam - 70% f. Ground Rules and Regulation/Discipline * Foolscap size exercise book for notes * Notes to be submitted for grading before mid-semester test and end of semester test * Disciplinary action will be taken against lateness to class and absenteeism g.
