Description
This lesson begins with a review of the hydraulic tools explained in Oil Pipeline Hydraulics and Hydraulic Tools. From there students review line operations by following 3 batches of crude oil down an actual line and discuss where each crude oil is, how they can tell, and potential operating problems and solutions. The lesson concludes with a line optimization case study.
Learning Objectives
-
Combine the systems resistance curve and pump curve graphs and explain how and why they show the operating point of the line.
-
Describe how control valves and variable speed drives are used to control flow.
-
Combine the systems profile and hydraulic gradient and explain:
-
What the distance between the profile and gradient shows
-
What happens when the hydraulic gradient falls below the system profile
-
Explain how to convert from psi to feet of head.
-
Explain why controlling pressure is the key to controlling rate.
-
Describe how the hydraulic gradient changes when the viscosity changes.
-
Describe how the hydraulic gradient changes when the rate changes.
-
Explain how to identify gravity changes in hydraulic profiles.
-
Describe column separation, what cause it and why it can be dangerous.
-
Discuss your key learnings from this lesson.
