I've already tried 4 components and 3 components and both were not right so I'm pretty stumped.

Hydrocarbon Absorption Count phases and components. An air stream with small amounts of hydrocarbons is to be treated in an adsorption process to reduce the amount of volatile hydrocarbon in the air stream. At the exit of the separation process, the solid sorbent is in equilibrium with a vapor stream that contains air and three hydrocarbons. How many intensive variables need to be specified to reduce the degrees of freedom to zero? You may take air to be one component
