To avoid excessive electrostatic effect in the crude oil washing process, due to the presence of water in the crude oil washing fluid, the contents of any tank to be used as a source of crude oil for washing must first reduce a portion of the tank contents by a vertical height equal to _______________.
AI Explanation
The correct answer is B) one meter.
The reasoning is that to avoid excessive electrostatic effect in the crude oil washing process, the contents of any tank to be used as a source of crude oil for washing must first have a portion of the tank contents reduced by a vertical height of one meter. This requirement is outlined in the regulations governing the crude oil washing process to ensure that water content in the washing fluid is minimized, which helps prevent the buildup of static electricity.
The other options are incorrect because a vertical height reduction of less than one meter (A) or more than one meter (C, D) would not adequately address the issue of water content and electrostatic effects as specified in the relevant regulations.
