CLASS 9 EUROINVENT 2009 CLASA 99.3.Method for selective separation of citric acid fromTitle ENfermentation brothsProcedeu de separare selectiva a acidului citric din lichidele deTitlu ROfermentatieAuthors Dan Cascaval, Anca-Irina Galaction, Lenuta KloetzerGheorghe Asachi Technical University, IaşiInstitutionFaculty of Chemical Engineering and Environmental ProtectionPatent no. RO 119629The patent presents a new method for selective separation ofcarboxylic acids (citric acid) from citric fermentation broths.DescriptionThe method consists on reactive extraction and increases theENseparation efficiency, decreases the required steps number and,implicitly, reduces the separation cost.DescriereROInventia se refera la un procedeu nou se separare selectiva aacizilor carboxilici (acidul citric) din lichidele de fermentatie.Aceste procedeu, bazat pe extractia reactiva, mareste eficientasepararii, reduce numarul de etape necesare purificarii si,implicit, reduce costurile separarii9.4.Equipment for extraction and transport through liquidTitle ENmembranes (pertraction)Titlu RO Instalatie pentru separarea prin membrane lichide (pertractie)Authors Dan Cascaval, Anca-Irina GalactionGheorghe Asachi Technical University, IaşiInstitutionFaculty of Chemical Engineering and Environmental ProtectionPatent no. RO 119690The equipment could be used for separation of the bioactivecompounds, with pronounced chemical and thermal lability, byextraction and transport through liquid membranes, without orDescriptionwith addition of a carrier (free or facilitated pertraction). ThisENequipment does not require the use of tensides for stabilizing theliquid membrane, thus increasing the purity of the pertractedcompounds.DescriereROInventia se refere la o instalatie de separare a unor compusibioactivi, labili chimic si termic, prin extractie si transport prinmembrane lichide (pertractie), in absenta (pertractie libera) sauin prezenta unor agenti purtatori (pertractie facilitata). Princonstructia sa, echipamentul nu necesita utilizarea unor agentide stabilizare a membranei lichide, ceea ce sporeste puritateacompusilor separati.90
