The Sat Liquids Unit separates streams into all of the following EXCEPT?

The Sat Liquids Unit in a refinery is designed to separate various hydrocarbon streams based on their boiling points and molecular weights. Typically, it focuses on separating lighter saturated hydrocarbons such as pentanes and butanes, which are part of the alkane family and readily separate within the range of the unit’s operational conditions.

Ammonia, in contrast, is a nitrogen-based compound that does not fall within the category of hydrocarbons being processed in a Sat Liquids Unit. This unit primarily deals with liquid hydrocarbon streams in the refining process, while ammonia is typically produced in separate units, such as ammonia synthesis reactors or through processes like steam reforming.

Fuel gas also contains a mix of hydrocarbons and is often generated or handled in other units of a refinery, but again, it does not align with the function of the Sat Liquids Unit, which focuses specifically on the separation of saturated liquid hydrocarbons.

Therefore, the absence of ammonia from the separation capabilities of the Sat Liquids Unit is what makes it the correct answer to this question.
