Morphology

fractional + process

The adjective 'fractional' (relating to fractions or parts) combined with 'process' readily suggests to a learner that this is a procedure that separates or produces parts, so the broad idea is inferable from the constituents. However, the specific technical meaning involving heating and differences in boiling points (i.e. fractional distillation/fractionation) is specialized and not predictable from the words alone, making the expression only partially transparent to a B1 learner.

Etymology

The noun fractional process comes from the image of heating a mixture so its parts boil away at different temperatures and are collected one by one. fractional means 'into parts' and process means a method, so the phrase refers to a way of separating a substance by using different boiling points.
