$10.$True or False: Atmospheric distillation units can process heavy residues left from crude oil refining, making them versatile in producing a wide range of petroleum products.

True or False: The degree of separation $(5-95$ gap$)$ in distillation is a key indicator of crude oil quality, with a larger gap suggesting a more valuable and easier$-$to$-$refine crude.

True or False: The degree of difficulty of separation $($t$50)$ is a critical parameter for designing refinery distillation units, as it directly impacts energy consumption and operational efficiency.

True or False: Packie charts are exclusively used for the analysis of sulfur and nitrogen compounds in crude oil, providing a basis for environmental compliance strategies.
