10. Computer Usage: • some  homework assignment • using accompanying CD • using Excel Sheet

11. HOMEWORK: For every homework problem assigned – unless other instructions are given- the following format is to be used: • Write down the problem statement • State the objective of the problem • Define the problem. Sketch, label, and state precisely what you want to find out. • Briefly write down how you want to solve the problem (the method). • Carry out the solution. • Review the results . Do you have any comments on the answers or on the problem? State them.

12. Course Assessment: • Homework • Computer Assignments • Quizzes • 3 Midterm Exams • Final Exam 10% 5% 15% 35% 35%

13. Attendance: • 25% absence will result into a DN grade. 25% of (2 lectures + 1 tutorial) x 15 = 11 • Maximum lateness allowed is 5 minutes. If you come more than 5 minutes late, you will be allowed to attend class, but you will be considered late. Each 2 late attendances will be considered as 1 absence.

14. Course Conduct Codes : In all aspects of the course honesty and trust are a must. Any violations will be severely confronted.

15. You will be working in class as follows: • individually • As a team • For homework, quizzes and exams you must work individually • LET US NOW CONSTRUCT THE TEAMS • EACH ONE MUST DO HIS DUTY

16. INTRODUCTION Individually: Take 5 minutes and write down “ What do you know about Chemical Engineering, what processes does chemical engineering involve?

17. INTRODUCTION As a team: Take 5 minutes and write down “ What do you know about Chemical Engineering, what processes does chemical engineering involve?

18. INTRODUCTION • Processes involved in ChE • mixing • separation - distillation absorption freezing extraction (heat mass and momentum transfer) • chemical reactions

19. What is the difference between a chemical engineer and a chemist? • Chemist: • works in test tubes • small quantities • batch constant-T experiments • small containers • a catalyst is added and reactions proceed with time

20. A CHEMICAL Engineer: • works with large quantities • large equipment • continuous mode • feed streams and product streams are continuously fed and withdrawn from the process • steady state operations (all parameters such as T, P, liquid livel, flow rates, compositions, etc. are all constant with time

21. CHEMICAL Engineer: • scaling up • works closely with mechanical, electrical, civil, and metallurgical engineers in order to design and operate the physical equipment in a plant ( such as: ? )

22. What are the typical activities a chemical engineer works with? 1. DEVELOPMENT : to commercialize (scale up) a chemical process Lab size process  pilot plant  plant

23. 2.DESIGN: A team of engineers design the commercial plant, based on experience and data obtained from the Lab size process and the pilot plant. The Chem E specifies: • Process flow rates and conditions • Equipment types and sizes • Materials of constructions • Process configuration • Control systems • Safety systems • Other

24. 3.CONSTRUCTION : Assembling of all components into a complete plant • 4.MANUFACTURING : running the plant or operations and production. Things that are important and relevant: • efficiency • safety • design modifications • reduce costs • improve product quality • reduce pollution

25. 5. TECHNICAL SALES 6. RESEARCH
