Chapter 1: Introduction to Chemical Engineering Profession 1.4 THE BUILDING
BLOCKS OF CHEMICAL ENGINEERING
Course Learning Outcome:
To explain and identify the building blocks of chemical engineering
It is true that chemical engineers are comfortable with chemistry, but they do much more with this knowledge than just make chemicals. In fact, the term “chemical engineer” is not even intended to describe the type of work a chemical engineer performs. Instead it is meant to reveal what makes the field different from the other branches of engineering.
All engineers employ mathematics, physics, and the engineering art to overcome technical problems in a safe and economical fashion. Yet, it is the chemical engineer alone that draws upon the vast and powerful science of chemistry to solve a wide range of problems. The strong technical and social ties that bind chemistry and chemical engineering are unique in the fields of science and technology. This marriage between chemists and chemical engineers has been beneficial to both sides and has rightfully brought the envy of the other engineering fields.
Building blocks of chemical engineering
More typically, chemical engineers concern themselves with the chemical processes that turn raw materials into valuable products. The necessary skills encompass all aspects of design, testing, scale-up, operation, control, and optimization, and require a detailed understanding of the various “unit operations”, such as distillation, mixing, and biological processes, which make these conversions possible. The building blocks of chemical engineering basically utilizes mass, momentum, and energy transfer along with thermodynamics and chemical kinetics to analyze and improve on these “unit operations.” Figure 1.4.1 is the basic building blocks of chemical engineering.

The course introduces topics on the different kinds of heat transfer i.e. conduction, convection and radiation in different cases, types of heat exchangers and finally introduction on boiling and condensation processes.
Chemical Engineering Reaction
Chemical reaction engineering is the heart of chemical engineering as it serves as the fundamental difference of this branch of engineering to fields like mechanical and electrical engineering. The basic of chemistry is used in the review for some definition of important terms used in chemical kinetics prior to the calculation in chemical reaction engineering. This is followed by the types and operation of common industrial reactors. The topic on industrial catalyst is included as deemed important in real chemical processes.
This course involves the study of mass and heat transfer as well as the performance of equipment for solvent extraction, leaching, gas absorption and distillation.

Chapter 1: Introduction to Chemical Engineering Profession
Use correct terminology (standard commands)
Time the message to be sent when the receiver is able to listen Use appropriate vocal tone and volume. Commands must be heard and perceived as an imperative, not a question or comment.
Be relevant to the receiver, not a distraction. The message needs to be inclusive and informative.
The receiver needs information to accomplish his/her task. The effectiveness of the team often rests on its member’s ability to listen. Unfortunately, most people find listening difficult.
The receiver must exert control over the communication process. For receivers to have control, it is important that they ensure that the senders understand what the receivers want and why they want it.
Active listening is a process used by the receiver to facilitate communication and enhance performance. It requires the receiver to be active
in the communication process. To actively listen, the receiver needs to:
Focus attention on the message, giving it momentary priority. If possible, look at the sender
Listen and look for the indirect message content (nonverbal) as well as hearing the words. Observing non-verbal cues provides information regarding what the sender wants to convey. Your perception of the message and the sender’s intent for the message may be different. Word choice, tone of voice, body position, gestures, and eye movements reflect the feelings behind the spoken word.
Keep an open mind and suspend judgment
Verify what was heard. Don’t assume that your perception of the message agrees with the sender’s intent. Provide the sender feedback. Message feedback
Effective receivers verify their understanding of the message with the sender. They consider words, tone and body language when they give feedback. Forms of feedback include:
Chapter 1: Introduction to Chemical Engineering Profession Acknowledging
“Rogering” a message is common courtesy. It demonstrates that the receiver has heard the message. However, for critical information or complicated ideas, acknowledgement normally is insufficient to ensure understanding.
Parroting is repeating back verbatim the words of the speaker. It confirms to the speaker that the words transmitted were the words received. It is preferred in verifying receipt of standard commands. Like acknowledgement,
it does not ensure the receiver understood the message
Paraphrasing is rephrasing, in your own words, the content of the sender’s message to the sender’s satisfaction. It clarifies the message for both you and the sender. Paraphrasing allows you to check your understanding of the message and shows the sender, that you listened accurately (i.e the content and intent was correctly understood). If you listened inaccurately, the sender has an opportunity to correct the communication error.
Definition of Teamwork
No matter how hardworking, brilliant, or good at problem solving you are, you can’t do it all by yourself. In today’s world, projects are usually too big to be completed by one person, and problems are often too complex to be solved by one person. Instead a team of people needs to be involved. And when people work together, personalities and communication styles come into play. To become someone who can succeed in a team setting means becoming someone who can succeed at any job.
People form groups of all types and sizes. However, not every group is a team. Team can be defined as:
Two or more individuals with a high degree of interdependence geared toward the achievement of a goal or the completion of a task. Teams make decisions, solve problems, provide support, accomplish missions, and plan their work.
Slows down the problem-solving process because of discussion and disagreements. This is particularly true when teams grow larger. As a result, deadlines may be compromised
Potentially challenging for employees who prefer working alone or are not comfortable working with people with widely divergent skills and backgrounds
Allows some team members to do less work that others and not participate as much
Basic methods on how to develop Teamwork
It’s important to realize that the development of effective working relationships among staff is a gradual process which requires considerable time and skill. This is not meant to discourage you, but to help you realize that teams aren’t created overnight. A certain amount of frustration and conflict are normal. Team development is often viewed as a series of stages, described below. Although all the attributes and skills needed for an ideal working relationship (as listed in the preceding section) are important at every stage, some become more crucial as the team develops and staff members increase their level of involvement.
At a minimum, it’s important for individual staff members to realize the benefits of teamwork and to have a commitment toward working together. Without such elements, further team development will be less likely to occur. Conflict, a natural part of the development process, will overpower or dominate the situation, reventing the team from ever reaching its full potential. With a positive attitude toward team efforts, and with increased opportunity and time to practice teamwork
skills, staff members can develop as an effective working team, and consequently have greater impact upon clientele problems.
Stages of Team Development:
Stage 1: Hello, I Am…
Getting acquainted is of most concern at this initial stage of team development. It usually includes polite dialogue of a superficial, information-sharing nature. Based on first impressions or past experiences, group members develop stereotypes in an attempt to categorize each other and anticipate future responses. Ideas are simple; emotions and feelings are kept in tight control, and controversy is avoided. There is an unspoken agreement not to disagree-a feeling that all members think and feel alike. Items on the hidden agenda stay hidden, and there is a shared ambiguity about the specific task to be undertaken by the team.
