The size reduction takes place, in this instance, in that the volume of the light fraction LF contained in the remaining fractions is increased, whereby in a later process step V7 an improved and purer fraction separation of {HEAD ~ the remaining fractions} into {TAIL ~ a light fraction} LF and a heavy fraction SF is made possible
