What is the normal direction of flow through the device shown in the illustration while operating in the processing mode? Illustration GS-0153

Correct Answer: Option B — The oily-water mixture enters through valve "5" and exits the separator through valve "14" as processed liquid.

Operational flow in a separator requires the oily-water mixture to enter the lower section through the inlet valve '5'. As the mixture passes through the coalescer beds, oil separates and rises, while the processed water exits through the discharge valve '14' located at the bottom or side.
