How are the **key components of lightness and heaviness classified?

Component Boiling Point 2-methylpentane 60 3-methylpentane 63.3 n-hexane 68.74 methylcyclopentane 71.83 naphthalene 217.9 It is required that no naphthalene be detected at the tower top, and the recovery rate of light components should be greater than 95%； The recovery rate of naphthalene at the bottom of the tower is greater than 95%. How to determine the key components of varying importance and their recovery rates when using simplified methods for simulation?
The key component is likely to be naphthalene. As for the less important components, if there are no specific requirements, decisions should generally be made based on economic considerations. Please check which of these components has a higher value; that one can then be considered as the key component, with attention being paid to its yield. . . Personal opinion, hehe
