Abstract
A method of monitoring breakthrough of an adsorbent bed consisting for example of ion-exchange resins, used during a stage of purification of an ester stream containing glycerin, obtained for example in a vegetable or animal oil and aliphatic monoalcohol transesterification process, permits the instantaneous detection of the presence of glycerol (glycerin) in the ester stream by arranging a turbidimeter at the adsorbent bed outlet.
