It was shown that 79.9% of the total amount of phenol permeated through the membrane was collected as crystals,
and the remaining 20.1% was collected as an aqueous solution in the second trap when the feed concentration was 6000 ppm. This corresponds to a phenol crystal production rate of 123 g/(m2 h), which is impressive because this is obtained from a dilute aqueous solution by pervaporation only. At a given
