What is the primary function of item '15'...

🔍 Key Concepts

• Trace the piping connected to item 15 to see where it takes suction and where it discharges. • Understand the roles of area 23 (evaporator/brine section) and area 24 (condenser/distillate section) in a flash-type distilling unit. • Consider how the chemical cleaning system would be arranged in the diagram (look at item 12 and nearby lines).

💭 Think About

• Follow the line from item 15 backward: from which section or space does it draw fluid—23, 24, or another low point? • Follow the line from item 15 forward: does it send the fluid to overboard, a drain, back to the evaporator, or into a cleaning loop? • Compare the function implied by that flow path with each choice: which option matches what that pump would realistically be doing in normal or secured operation?

✅ Before You Answer

• Verify whether item 15 is symbolized as a pump (look at the symbol shape and nearby motor or drive). • Check if the suction side of item 15 is connected to the bottom/low point of area 23 or 24, or to a separate drain/chemical tank line. • Confirm whether valve 12 is in the same loop as item 15, and whether that loop appears to be a temporary cleaning circuit or a drain/emptying line.

What is the primary function of item '15' shown in the illustration? Illustration MO-0111

It is the chemical cleaning pump used in conjunction with valve "12".

It removes the vapor condensed in area "23".

It removes the distillate condensed in area "24".

It is used to empty the evaporator section when there is tube leakage while the unit is secured.
