Correct Answers & Detailed Rationales
Based on Turton, Shaeiwitz, Bhattacharyya & Whiting (Pearson, 2018/2021)
Section I: Conceptualization and Analysis of Chemical
Processes (Questions 1–40)
Chapter 1: Diagrams for Understanding Chemical Processes
,1. Which diagram type provides the most detailed representation including all
instruments, control loops, piping specifications, and safety devices?
A. Block Flow Diagram (BFD)
B. Process Flow Diagram (PFD)
C. Piping and Instrumentation Diagram (P&ID)
D. Process Concept Diagram
Rationale: The P&ID is the most detailed diagram, essential for plant construction and
operation. It shows all piping, instrumentation, and control schemes .
2. A Block Flow Diagram (BFD) primarily shows:
A. Major process blocks with minimal stream information
B. Complete equipment specifications
C. All control loops
D. Pipe sizes and schedules
Rationale: BFDs are used in early conceptual design stages, showing the overall process
in terms of major blocks representing process steps with minimal stream information .
3. The primary difference between a PFD and a P&ID is:
A. A PFD shows instrumentation; a P&ID does not
B. A PFD shows process flow; a P&ID shows piping and instrumentation details
C. A PFD is used for construction; a P&ID is used for conceptual design
D. A PFD is hand-drawn; a P&ID is computer-generated
Rationale: A PFD shows process flow (streams, equipment, and interconnections) and is
used for process design. A P&ID shows piping and instrumentation details and is used
for construction and maintenance .
4. What information is typically included in a PFD?
A. Only equipment identification numbers
B. Stream flow rates, compositions, temperatures, pressures, and equipment
information
C. Only piping specifications
D. Only control loop details
Rationale: A PFD includes stream information (flow rates, compositions, temperatures,
pressures) and equipment information (identification, type, size). It is the primary
document for process design .
,5. A 3-D plant model is reviewed prior to construction primarily to:
A. Determine equipment color
B. Check for clearance, accessibility, and layout of equipment, piping, and
instrumentation
C. Calculate reaction kinetics
D. Select catalysts
Rationale: 3-D model reviews identify spatial conflicts and accessibility issues that
cannot be detected in 2D drawings, preventing costly field modifications .
6. Which of the following is NOT typically checked during a 3-D model review?
A. Clearance for tube bundle removal on heat exchangers
B. NPSH on pumps
C. Equipment purchase cost
D. Accessibility of instruments for operators
Rationale: Cost estimation is not part of a 3-D model review. The review focuses on
physical layout, clearance, accessibility, and operational considerations .
7. The primary purpose of a Process Concept Diagram is to:
A. Show detailed piping layout
B. Illustrate the overall process concept and material flows
C. Specify equipment dimensions
D. Detail control strategies
Rationale: The Process Concept Diagram is used to illustrate the overall process
concept before detailed design begins .
Chapter 2: The Structure and Synthesis of Process Flow Diagrams
8. What is the first step in the hierarchy of process design?
A. Design of the separation system
B. Batch versus continuous process selection
C. Design of the heat-exchanger network
D. Design of the reactor
, Rationale: The first step in the hierarchy of process design is to decide whether the
process should be batch or continuous. This decision affects all subsequent design
decisions .
9. The "onion model" of process design suggests that design should proceed:
A. From the outside in, starting with the separation system
B. From the inside out, starting with the reactor
C. From the heat-exchanger network inward
D. From the control system outward
Rationale: The "onion model" suggests design should proceed from the inside out: first
the reactor (the core), then the recycle system, then the separation system, and finally
the heat-exchanger network .
10. The five elements of the Hierarchy of Process Design are:
A. Reactor, separator, heat exchanger, pump, compressor
B. Batch vs. continuous, input/output structure, recycle structure, separation
system, heat-exchanger network
C. Conceptual, preliminary, detailed, construction, operation
D. Mass balance, energy balance, economics, safety, environment
Rationale: The hierarchy includes: batch vs. continuous, input/output structure, recycle
structure, separation system, and heat-exchanger network .
11. The recycle structure significantly affects:
A. Only the color of piping
B. The size of the reactor, separator, and associated equipment
C. Only the control system
D. Only the utilities
Rationale: Recycling unreacted materials increases the total flow through the reactor
and separator, affecting their sizes and the overall economics .
12. The primary function of the separation system is to:
A. React raw materials to form products
B. Purify products and recover unreacted materials for recycle
C. Generate steam for the process
D. Control the process temperature
