Instructions: Choose the best answer for each question.
1. Which of the following is NOT a common component of organic deposits in pipelines?
a) Paraffin (wax)
This is a common component.
b) Asphaltene
This is a common component.
c) Iron Oxide
This is the correct answer. Iron oxide is a mineral deposit, not organic.
d) Tar
This is a common component.
2. What is a significant consequence of organic deposit buildup in pipelines?
a) Increased flow capacity
This is incorrect. Deposits reduce flow capacity.
b) Reduced pressure drop
This is incorrect. Deposits increase pressure drop.
c) Improved equipment longevity
This is incorrect. Deposits damage equipment.
d) Increased energy consumption
This is the correct answer. Deposits necessitate higher pressure, increasing energy consumption.
3. Which of the following factors can contribute to organic deposit formation?
a) High flow velocities
This is incorrect. Low flow velocities promote deposition.
b) Low water content in crude oil
This is incorrect. Water can accelerate deposit formation.
c) Consistent temperature and pressure
This is incorrect. Fluctuations in temperature and pressure can trigger deposition.
d) High concentrations of wax in crude oil
This is the correct answer. Wax is a major contributor to organic deposits.
4. Which of the following is NOT a proactive strategy for mitigating organic deposit formation?
a) Chemical inhibition
This is a common strategy.
b) Pipeline pigging
This is a common strategy.
c) Replacing old pipelines with newer ones
This is the correct answer. While replacing pipelines can help, it is not a proactive strategy for ongoing deposit prevention.
d) Heat tracing
This is a common strategy.
5. What is the primary benefit of regular pipeline monitoring in relation to organic deposits?
a) Reducing the cost of chemical inhibitors
This is incorrect. Monitoring helps with early detection, not cost reduction.
b) Increasing the efficiency of pipeline pigs
This is incorrect. Monitoring helps with early detection, not pig efficiency.
c) Enabling timely intervention to prevent major problems
This is the correct answer. Early detection allows for prompt action to prevent severe issues.
d) Reducing the need for pipeline design considerations
This is incorrect. Design considerations are crucial for preventing deposits.
Scenario: You are an engineer responsible for a new oil pipeline transporting crude oil with a high wax content. Describe three specific steps you would take during the pipeline design phase to minimize the risk of wax deposition.
Here are some possible steps, focusing on proactive design considerations:
