Process Units and Degrees of Freedom Analysis. Material Balance on Single-Unit Process. Multiunit Process Calculations. Material Balances on Reactive Systems. Single- and Multiphase Systems. Energy and Energy Balances. Energy Balance with Reaction. Simultaneous Material and Energy Balances. Unsteady-State Material and Energy Balances. The book is mainly intended for junior chemical engineers.
The focus is on single and multiphase systems related to material and energy balances. This material is introduced in a manner that there will be little lecture content. The material intrusion theory is explained briefly and simply to make this book more user-friendly.
Many examples are included and solved in a simple and understandable format that explains the related theory. The book can be covered in one semester if based on a four-hour contact course or two semesters on a two-hour contact course.
A new chapter related to single and multiphase systems has been added. Course Objectives At the completion of this course, students will 1. Understand processes typical of those found in the chemical and bio process industries 3. By the end of this course, each student should be able to 1.
Explain the concepts of dimensions, units, psychrometry, steam properties, and conservation of mass and energy 2. Solve steady-state and transient mass and energy balance problems involving multiple-unit processes and recycle, bypass, and purge streams 3. Solve and understand simple unsteady-state mass and energy balances 4. Solve more complicated problems using the software appropriate for the problem 5. An ability to identify, formulate, and solve engineering problems 2. An ability to communicate effectively 3.
PowerPoint presentations that explain the simulations and property estimation using HYSYS are also available to instructors. For the last 50 uses, a warning will be issued where the software will indicate the number of trials remaining and gives information as to where the software can be purchased.

We also extend our thanks to all professors who are teaching or contributing to this subject. The feedback from Professor Douglas R. Lloyd and David Himmelblau and others is highly appreciated. He has published more than 40 journal papers, primarily in the areas of modeling and simulation, bifurcation theory, gas-liquid separation using membrane contactor, and fabrication of polymeric hollow fiber membranes.
He has taught numerous core courses in chemical engineering at the undergraduate and graduate levels. Among the recognitions he has received are fellowships from the French Ministry of Higher Education and the German Alexander von Humboldt Foundation, as well a scholarship from the Research Council of Norway. Henda is a licensed professional engineer in Ontario and has served on the editorial boards of numerous journals.
The chapter is organized to provide newcomers with a view of what chemical engineering is. This chapter begins with addressing this question. Next, the system of units and how to carry out conversions between units are reviewed.
This is followed by an explanation of the use of an appropriate number of significant figures in calculations. The concept of dimensional homogeneity and how it can be used to identify valid and invalid equations are explained.
Then, types of manometers and how to calculate pressure based on the type of manometer used are explained. The following outlines the major learning objectives of this chapter. Learning Objectives 1. Understand what chemical engineering is about Section 1. Have a working knowledge of units and conversion between units Section 1.
Determine and use the appropriate number of significant figures Section 1. Identify an invalid equation based on dimensional arguments Section 1. Calculate process stream flow rates in a variety of units Section 1. Calculate stream compositions in a variety of units Section 1. Be aware of the importance of material and energy balances Section 1. Principles of Chemical Engineering Processes 1. Because of the reliance of chemical engineering on principles and laws that are versatile in the natural world, the possibilities offered to by chemical engineering as well as the challenges faced by chemical engineers are quite formidable and constantly changing.
A typical problem in the design of a new process or the modification of an existing process is as follows: "Given the amount and the properties of the raw materials, calculate the amount of the products and determine their properties or vice versa.
For example, in a statement like "2. A measured or counted quantity has a numerical value e. It is necessary in engineering calculations to report both the value and the unit. Measurable units are specific values of dimensions that have been defined by convention, such as grams for mass, seconds for time, and centimeters for length. Units can be treated like algebraic variables when quantities are added, subtracted, multiplied, or divided. Derived units can be obtained by multiplying or dividing base units i.
Table 1. For example, velocity may be expressed in terms of feet per second, miles per hour, centimeters per year, or any other ratio of length and time. To convert a quantity expressed in terms of one unit to its equivalent in terms of another unit, you will need to multiply the given Principles of Chemical Engineering Processes TABLE 1.
TABLE 1. Example 1. Convert a volume of 5 ft 3 to its equivalent in m 3. Analysis: Use the table of conversion factors. We can measure temperature using physical properties of a substance, which change as a function of temperature.
Common temperature scales are listed as follows : 1. Fahrenheit: On this scale, the freezing point of water is 32 and boiling point is Celsius: The freezing point of water is 0 and boiling point is Principles of Chemical Engineering Processes 3.
Analysis: Use temperature conversion relations 1. The number of significant figures is readily seen if scientific notation is used. Scientific notation is generally a more convenient way of representing large numbers Tables 1. Numbers can be written in either standard notation or scientific notation to show significant figures. With decimal point Count from nonzero on the left to the last digit on the right: 0. Without decimal point.
Scientific notation: Typically only significant figures are shown: 1. It is simply that a final result should be listed to no more significant figures than the least accurate factor in the expression evaluated. For example, the distance traveled by a vehicle moving at a velocity of The fact that your calculator may list
A mass balance , also called a material balance , is an application of conservation of mass to the analysis of physical systems. By accounting for material entering and leaving a system, mass flows can be identified which might have been unknown, or difficult to measure without this technique. The exact conservation law used in the analysis of the system depends on the context of the problem, but all revolve around mass conservation, i. Therefore, mass balances are used widely in engineering and environmental analyses. For example, mass balance theory is used to design chemical reactors , to analyse alternative processes to produce chemicals, as well as to model pollution dispersion and other processes of physical systems.
