Direct Answer
Option A: Crystallisation
Crystallisation is the process where a pure solid separates from a solution in the form of crystals. This purification technique is relevant on chemical tankers when handling cargoes prone to solidification or crystallisation due to temperature drops, affecting pumpability and tank cleaning requirements (P&A Manual).
