What is NOT a requirement for the safe and effective use of a crude oil washing system?
AI Explanation
The correct answer is B) Use portable washing machines to reach areas obscured by structural members in the tanks.
This is because the safe and effective use of a crude oil washing system does not require the use of portable washing machines. Crude oil washing systems typically use fixed in-tank cleaning machines that are designed to reach all areas of the tank, including those obscured by structural members. The use of portable washing machines is not a necessary requirement for the safe and effective use of a crude oil washing system.
The other answer choices are incorrect because: A) Stripping tanks and removing bottom residue is a necessary requirement, C) Decanting one meter from the source tank is also a requirement, and D) Using an inert gas system is a requirement for the safe and effective use of a crude oil washing system.
