Impurity removal by separation and crystallisation are the most important process operations in a refinery. This paper studies the main separation processes, namely clarification, decolourisation and crystallisation to demonstrate where poor separation contributes to excessive costs of processing. The results of various tests are analysed and conclusions are made for refiners to manage their chemical and fuel costs.
