$25.$ The degree of separation, particularly the $5-95$ gap, is a critical parameter in distillation that influences the $\_\_\_\_$ of the process, affecting both $\_\_\_\_$ and $\_\_\_\_$ in the refinery.

$26.$ In crude oil processing, the desalting stage is crucial for removing $\_\_\_\_$ and $\_\_\_\_$ from the crude, preventing $\_\_\_\_$ and $\_\_\_\_$ damage in downstream units.

$27.$ The stabilization of crude oil aims to reduce its $\_\_\_\_$ pressure by removing $\_\_\_\_$ and $\_\_\_\_,$ making it safer for $\_\_\_\_$ and $\_\_\_\_.$

$28.$ Fractional distillation in refineries separates crude oil based on $\_\_\_\_$ points, yielding products like $\_\_\_\_,\_\_\_\_,$ and $\_\_\_\_$ for various market needs.
