Computer Usage: some homework assignment using accompanying CD using Excel Sheet

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.

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

Attendance: 1. 25% absence will result into a DN grade. 25% of (2 lectures + 1 tutorial) x 15 = 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.

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

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

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

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

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

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

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with large quantities - large equipment - continuous mode - feed streams and product streams are continuously fed and withdrawn from the process - steady state operations (all parameters such as T, P, liquid livel, flow rates, compositions, etc.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

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: ? )

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

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

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

5. TECHNICAL SALES 6. RESEARCH
