Deck 13: Process Drawings

Question 1

What type of diagrams are the simplest drawings used in the process industries?

A) Process Flow Diagrams (PFDs)
B) Block Flow Diagrams (BFDs)
C) Engineering Flow Diagrams (EFDs)
D) Piping and Instrumentation Diagrams (P&IDs)

Answer 1

B
Explanation: A) Incorrect. Process flow diagrams allow process technicians to trace the step-by-step flow of a process.
B) Correct. Block Flow Diagrams (BFDs) diagrams are the simplest drawings used in the process industries.
C) Incorrect. Engineering flow diagrams contain all process plant information, including equipment, flows to and from each piece of equipment, and the explanation of those flows and products.
D) Incorrect. Piping and Instrumentation Diagrams (P&IDs) are similar to process flow diagrams but provide more complex process information.

Question 2

What type of diagram helps process technicians understand power transmission and its relation to the process?

A) Plot Plan Diagrams (PPDs)
B) Utility Flow Diagrams (UFDs)
C) Engineering Flow Diagrams (EFDs)
D) Electrical Diagrams

Answer 2

D
Explanation: A) Incorrect. Plot Plan Diagrams (PPDs) are usually an architectural rendition of a process plant showing equipment layout, road positioning, and proposed construction on a defined scale.
B) Incorrect. Utility Flow Diagrams (UFDs) provide process technicians with a P&ID-type view of the utilities used for a process.
C) Incorrect. Engineering Flow Diagrams (EFDs) diagrams contain all process plant information, including equipment, flows to and from each piece of equipment, and the explanation of those flows and products.
D) Correct. Electrical Diagrams help process technicians understand power transmission and its relation to the process.

Question 3

What type of diagram shows the relationship of units and equipment to a facility's boundaries?

A) Elevation diagrams
B) Loop diagrams
C) Equipment location diagrams
D) Wiring diagrams

Answer 3

C
Explanation: A) Incorrect. Elevation diagrams represent the relationship of equipment to ground level and to other structures.
B) Incorrect. Loop diagrams show all components and connections between a specific instrumentation loop and the control room.
C) Correct. Equipment location diagrams show the relationship of units and equipment to a facility's boundaries.
D) Incorrect. Wiring diagrams shows electrical components in their relative position in the circuit and all connections between components.

Question 4

What is the main part of a drawing; it contains symbols and defines elements such as relative position, types of materials, descriptions, and functions?

A) Legend
B) Symbol
C) Title block
D) Application block

Question 5

What type of electrical diagram shows the direction of current flow in a circuit, typically beginning at the power source?

A) Schematics
B) Wiring diagram
C) Simulation
D) Isometric drawings

Question 6

What type of diagram contains all process plant information, including equipment, flows to and from each piece of equipment, and the explanation of those flows and products?

A) Plot Plan Diagrams (PPDs)
B) Utility Flow Diagrams (UFDs)
C) Engineering Flow Diagrams (EFDs)
D) Electrical Diagrams

Question 7

What type of diagrams are usually an architectural rendition of a process plant showing equipment layout, road positioning, and proposed construction on a defined scale?

A) Plot Plan Diagrams (PPDs)
B) Utility Flow Diagrams (UFDs)
C) Engineering Flow Diagrams (EFDs)
D) Electrical Diagrams

Question 8

What is an example of information provided in the title block?

A) Functions

D) Approval signatures

Question 9

What purpose of process drawings uses a common set of lines and symbols to represent components?

A) Simplify
B) Knowledge
C) Standardize
D) Visual representation

Question 10

What are figures used to designate types of equipment and instrumentation?

A) Legend
B) Symbol
C) Title block
D) Application block

Question 11

What do process drawings do for a process technician?

A) Perform maintenance on equipment
B) Become familiar with the process(es) in a real-time environment
C) Understand or explain a process and how it relates to other processes
D) Learn how to use new equipment
