Which of the following evaporator separates volatile and nonvolatile compounds?

Which of the following evaporator separates volatile and nonvolatile compounds? Correct Answer Falling film evaporators

In falling film evaporators, the liquid product usually enters the evaporator at the head of the evaporator. The liquid enters the heating tube and forms a thin film on the tube wall where it flows downwards at boiling temperature and is partially evaporated. In most cases, steam is used for heating the evaporator.
