š Key Concepts
ā¢ Trace the line connected to item 10 and see where the fluid is coming from and going to.
ā¢ Identify what device 9 and device 11 represent in this separator/distillation system (pump, valve, or something else).
ā¢ Notice whether item 10 is located on a suction line, discharge line, or bypass line, and how that usually affects its function.
š Think About
ā¢ Follow the piping from device 9 through item 10 and then to item 11: what would be the purpose of placing a component in that exact spot?
ā¢ Compare the symbols for items 10, 11, and 13ā16. Which ones are pumps, which are valves, and which are control or protective devices?
ā¢ Ask yourself: is item 10 mainly changing direction, changing pressure/flow, or smoothing out conditions before the next component?

Before You Answer
ā¢ Verify whether the piping connected to item 10 leads to the distillate or drain side of the system.
ā¢ Confirm from the symbol whether item 10 is a valve, fitting, or special control device (it should match others on the diagram).
ā¢ Check how item 10 relates to device 9 and device 11: is it upstream, downstream, or in a bypass loop? This relationship is critical to its purpose.
