Résumé -Applications de la DSC pour la caractérisation des systèmes émulsifiés -Cet article décrit comment l'analyse calorimétrique différentielle (DSC) peut être utilisée pour caractériser les émulsions, en particulier les émulsions eau-dans-huile opaques et concentrées rencontrées dans l'industrie pétrolière. Après une présentation de la technique, nous expliquerons comment il est possible, à partir d'un simple test réalisé sur un échantillon d'émulsion non dilué, d'obtenir des informations sur les propriétés de solidification et de fusion de ces systèmes complexes, notamment le type d'émulsion, la quantité d'eau, la présence de soluté, la stabilité et même la taille des gouttes. Quelques exemples d'applications sont donnés, en particulier sur les émulsions de champ rencontrées en production et sur les boues de forage à base d'huile.

Re´sume´-Conge´lation dans les e´mulsions : aspects the´oriques et applications techniques -Cet article se concentre principalement sur le comportement a`la conge´lation des e´mulsions qui sont conside´re´es soit comme des syste`mes permettant d'obtenir des informations sur les mate´riaux en surfusion, soit comme des syste`mes disperse´s complexes implique´s dans les proce´de´s industriels. En raison du fait qu'il existe une phase disperse´e sous forme de fines gouttelettes dans les e´mulsions, des retards a`la solidification sont observe´s et les gouttelettes de liquide persistent meˆme en dessous du point de fusion du mate´riau. La corre´lation entre la tempe´rature de solidification des gouttelettes et leur taille peut eˆtre donc utilise´e pour suivre l'e´volution de la morphologie de l'e´mulsion en fonction du temps aussi bien sur terre que dans des conditions de microgravite´(projet FASES soutenu par l'ESA). Une description de ces phe´nome`nes observe´s principalement par microcalorime´trie sera donne´e pour des corps purs disperse´s ainsi que pour des solutions disperse´es. Dans certains cas, les e´mulsions peuvent eˆtre recherche´es pour leurs proprie´te´s spe´cifiques, telles que la grande taille de l'interface huile/eau, conduisant a`des transferts de masse ame´liore´s; les e´mulsions peuvent eˆtre par conse´quent utilise´es comme des membranes liquides pour l'extraction, le stockage et la libe´ration controˆle´e de matie`res actives. Dans d'autres cas, la formation d'e´mulsions a un effet ne´faste sur les proce´de´s, comme dans l'industrie pe´trolie`re ou`des e´mulsions eau-dans-pe´trole tre`s stables se forment facilement et compliquent l'ope´ration de de´shydratation du pe´trole brut.Abstract -Freezing Within Emulsions: Theoretical Aspects and Engineering Applications -This article is mainly focused on the freezing behaviour of emulsions which will be considered either as systems permitting to get information about undercooled materials or as complex dispersed systems involved in industrial processes. Due to the fact that there exists a phase dispersed as tiny droplets in emulsions, solidification delays are observed and liquid droplets are still observed under the melting points of pure materials. The correlation between the solidification temperature of the droplets and their size may be therefore used to follow the evolution of the emulsion morphology versus time on ground as in microgravity conditions (FASES project supported by ESA). A description of these phenomena mainly observed through microcalorimetry experiments will be given for dispersed pure materials as for dispersed solutions. In some cases, emulsions may be sought after for their specific properties, such as their large oil/ water interface, leading to enhanced mass transfers; emulsions may be consequently used as liquid membranes for extraction, storage and controlled release of active materials. In other cases, the formation of emulsions has a detrimental effect on the process. It is the case in the oil industry where very stable w...

The formulation of omega-3 emulsion using rubber (Hevea Brasiliensis) seed oil based on the best performance of the emulsion in terms of higher viscosity, smaller droplet size, lower moisture content and slightly acidic pH value supported by degree of creaming in varying the type and composition of emulsifier used. Rubber seed oil contains significant value of alpha-linolenic acid which plays an important role in maintaining human health. Therefore, formulation of rubber seed oil emulsion is important to become a new source of omega-3 emulsion instead of fish oil. Rubber seed oil was mixed with distilled water and nonionic emulsifier which were lecithin and span 80 by homogenizer. From the analysis conducted, the best formulation was the emulsion with 50% of distilled water, 6% of lecithin and 47% of rubber seed oil.
