Question 114Safety & Environmental - QMED

The correct answer is C) the solvent effect of the crude oil. Both crude oil washing and water washing use direct impingement to remove residue from tanks. The key advantage of crude oil washing over water washing is that the crude oil itself acts as a solvent, helping to dissolve and remove stubborn tank residues. The solvent properties of the crude oil make it more effective at cleaning the tanks compared to using just water. The other answer choices are incorrect because they do not represent the primary advantage of crude oil washing over water washing. Crude oil washing does not necessarily use higher temperature or higher pressure jets compared to water washing. The solvent effect of the crude oil is the key factor that makes it more effective at tank cleaning.
