Chapter 1 Flashcards
The approach to viewing interrelated components that work together is sometimes referred to as the systems concept or
Systems review
Systems thinking
Rational approach
Answer B
What is one of the advantages of looking at a chemical plant or a refinery as a group of systems?
It makes everyone focus exclusively on just one system
It requires everyone at all times to look at the components as individual elements
It’s provides the ability to connect the dots to see how everything fits together
Answer C
After seeing the “big picture” of how the systems in a plant facility relate, what is usually the next step for a student or new process technician?
The process technician can isolate the system and further break it down into smaller systems or subsystems to understand the parts.
The process technician memorizes all of the equipment, procedures, and materials used in that area.
Answer A
What statements are true
Process technicians must know why they are doing each individual step in a procedure
Process technicians do not need to know how one part of the system will affect other parts of the system.
Answer A
What are the three major categories of plant systems?
Separation systems, reaction systems, and utility systems
Utility systems, auxiliary systems, and process systems
Answer B
Which systems can be further divided into separation systems and reaction systems?
Refrigeration system
Process systems
Answer B
Which section in each chapter of the textbook typically has a control diagram for the system discussed in the chapter?
Instrumentation and Control
Components & Operating Principles
Answer A
What role do diagrams play in the work of process technicians?
Process technicians only need to rely upon drawings when they first learn about a system
Process technicians use drawings on a regular basis throughout their career.
Answer B
How does a block flow diagram (BFD) indicate how major sections of a system are linked?
By using blocks with lines indicating how these major sections are linked
By using blocks with symbols and icons between them indicating how these major sections are linked
Answer A
What is a process flow diagram?
A basic illustration that uses symbols and direction arrows to show the primary flow path of material through a process
A set of detailed drawings that uses simplified symbols to represent all of the equipment, piping, and instrumentation contained within a
process facility
Answer A
Where are energy balance tables sometimes added?
P&ID
BFD
Process flow diagram
Answer C
Where are piping specifications (size, piping material, and contents) usually included in a piping and instrumentation diagram (P&ID)?
As a footnote on a separate page
A pipe bubble
Answer B
When process technicians are operating a control station, they will typically work from ________.
control diagrams on the computer control screens
P&ID diagrams on computer screens
Answer A
New process technicians usually start learning about a process by using which diagrams?
BFD
PFD
P&ID
Answer A
Once new process technicians have become familiar with major equipment and piping, they can then advance to a more detailed drawing such as a ________.
data flow diagram
Block flow diagram
control diagram or P&ID
Answer C
Most of the systems covered in the text include a ________ showing the major equipment and process lines and describing how it is controlled
Utility flow diagram
Control diagram
Answer B
What is one of the more common advanced controls?
Cascade control
Control loop
Manual valve
Answer A
In a cascade control, what determines the set point used by the secondary controller?
The set point that is printed in the manufacturer’s documentation.
The set point signal is sent by the primary controller.
Answer B
