Question 145Safety & Environmental - 1st Asst/Chief
70% to passBoth crude oil washing and water washing use direct impingement to remove residue from tanks. Crude oil washing has an additional advantage, in utilizing _______________.
Aa higher pressure jet
Bthe solvent effect of the crude oil
Ca higher temperature
Dnone of the above.
AI Explanation
The correct answer is B) the solvent effect of the crude oil. Crude oil washing utilizes the solvent effect of the crude oil itself to remove more residues from the tank walls compared to water washing. The crude oil acts as a solvent, helping to dissolve and dislodge the stubborn oil and sludge deposits, making it more effective at cleaning the tanks than just using water alone. The other options are incorrect because: A) the pressure of the jet is not the key difference, C) the temperature is not a distinguishing factor between the two methods.
