1. What is the primary objective of chemical process design?
A. To maximize laboratory experiments
B. To develop a safe, economical, and efficient process
C. To eliminate all chemical reactions
D. To focus only on theoretical models
Rationale: Process design integrates safety, cost, and efficiency
to create viable industrial systems.
Correct Answer: B
2. Which step typically comes first in process synthesis?
A. Equipment sizing
B. Economic analysis
C. Problem definition
D. Control system design
Rationale: Defining the problem sets boundaries and objectives
for synthesis.
Correct Answer: C
3. What is a flowsheet in chemical process design?
,A. A financial report
B. A diagram showing process streams and equipment
C. A laboratory procedure manual
D. A safety checklist
Rationale: Flowsheets visually represent process operations
and material flow.
Correct Answer: B
4. What is the role of mass balance in process analysis?
A. To calculate profits
B. To ensure material conservation
C. To design equipment shapes
D. To predict chemical hazards only
Rationale: Mass balance ensures input equals output plus
accumulation.
Correct Answer: B
5. Which law is the foundation of material balance
calculations?
A. Newton’s Law
B. Law of Conservation of Mass
C. Boyle’s Law
D. Charles’ Law
,Rationale: Mass is neither created nor destroyed in chemical
processes.
Correct Answer: B
6. What is process synthesis mainly concerned with?
A. Selecting optimal process structure
B. Writing laboratory reports
C. Measuring temperature only
D. Avoiding chemical reactions
Rationale: Synthesis focuses on choosing the best process
configuration.
Correct Answer: A
7. A steady-state process implies that:
A. Temperature changes continuously
B. No accumulation occurs over time
C. Pressure is always zero
D. Reactions are stopped
Rationale: Steady-state means system variables do not change
with time.
Correct Answer: B
8. What is a recycle stream in chemical processes?
, A. Waste stream
B. Stream returned to earlier process stages
C. Final product stream
D. Cooling water outlet
Rationale: Recycle improves efficiency and resource utilization.
Correct Answer: B
9. The main purpose of energy balance is to analyze:
A. Financial profit
B. Heat and work interactions
C. Color of products
D. Equipment shapes
Rationale: Energy balance tracks heat and work in processes.
Correct Answer: B
10. Which is NOT part of process design decisions?
A. Equipment selection
B. Process configuration
C. Color of plant buildings
D. Operating conditions
Rationale: Aesthetic choices are not core design parameters.
Correct Answer: C
