Question 37Steam Plants - QMED

The correct answer is D) K, which is the lube oil sludge tank according to the illustrated lubricating oil system diagram SE-0011. The lube oil sludge tank is where spent or contaminated lubricating oil is collected and stored before disposal. This is a crucial component of the lubricating oil system, as it helps maintain the purity and integrity of the engine's lubricating oil supply. The other options (A, B, and C) represent different components of the lubricating oil system, such as the lube oil pump, lube oil filter, and lube oil cooler, respectively, but they are not the lube oil sludge tank.
