Question 626Steam Plants - Assistant Engineer
70% to passA centrifuge will satisfactorily remove which of the listed substances from lube oil?
AFuel oil
BDiesel fuel
CCarbon particles
DGasoline
AI Explanation
The correct answer is C) Carbon particles. A centrifuge is an effective way to remove solid contaminants like carbon particles from lube oil. The centrifugal force generated in a centrifuge separates the denser carbon particles from the lighter lube oil, allowing the particles to be extracted. The other options are incorrect because a centrifuge is not the best method for removing fuel oil, diesel fuel, or gasoline from lube oil. These are liquid contaminants that would require other purification techniques like filtration or distillation to remove effectively.
