What are the common fractions that are taken from a fractional distillation column that produces crude oil?
A fractional distillation column does not produce crude oil, it uses it as a raw material. The fractions that are removed will depend on the type of crude used, they are all different mixes. Typical output will include petrol, naphtha, diesel, paraffin. The required temperature can be varied by using pressure or vacuum in the column so there will be a range for each output depending on internal pressure. See http://en.wikipedia.
