RT info:eu-repo/semantics/article T1 Concentration by pervaporation of representative brown crab volatile compounds from dilute model solutions A1 Martínez Velasco, Rodrigo A1 Sanz Díez, Mª Teresa A1 Beltrán Calvo, Sagrario K1 Volatile compounds K1 Concentration K1 Pervaporation K1 POMS membrane K1 Chemical engineering K1 Ingeniería química AB In this work, the pervaporation technique is investigated in the separation of dilute solutions of volatile compounds from brown crab effluent in order to obtain a valuable food flavoring fraction. A systematic study of the pervaporation process has been carried out on dilute model solutions of some of the compounds identified in the brown crab effluent as typical volatile compounds. The membrane used in this work was a hydrophobic membrane with a selective layer of POMS (polyoctylmethyl siloxane). The effect of some operating variables, such as feed flow rate, feed concentration, feed temperature and permeate pressure was analyzed on the pervaporation performance of the membrane.
