The present invention provides an improvement to the two inaccurate, traditional approaches relating concentration to density. The first of these assumes that the solute is completely insoluble in the solvent; the second is based on a soluble solute. The present improved relationship is referred to the CONCENTRATION-DENSITY MODEL. This model allows for a theoretical determination of the concentration-density relationship for a multi-component solid/liquid (sand/water) or liquid/liquid (CMC/water) mixture. In the Concentration-Density Model is a new concept referred to as ADDITIVE VOLUME COEFFICIENT (AVC) (Fig. 1). This concept compensates for the fact that the net volume of a mixture does not always equal the sum of the volumes of each component. This improved Concentration-Density Model provides fluid-handling manufactures with a method for accurately determining a mixture's concentration on-line with the aid of current density measurement instrumentation.
La présente invention propose une amélioration de deux approches classiques et inappropriées concernant le rapport concentration-densité. La première stipule que le soluté est complètement insoluble dans le solvant, et la seconde se base sur un soluté soluble. La présente invention concerne un modèle concentration-densité. Ce modèle permet de déterminer de manière théorique le rapport concentration-densité pour un mélange solide/liquide (sable/eau) ou liquide/liquide (CMC/eau) à multiples composants. Le modèle concentration-densité présente un nouveau concept connu sous le nom de coefficient de volume d'addition (AVC) (Fig. 1). Ce concept compense le fait que le volume net d'un mélange n'est pas toujours égal à la somme des volumes de chaque composant. Ce modèle concentration-densité amélioré permet d'utiliser dans des installations de traitement de fluide un procédé permettant de déterminer avec précision la concentration d'un volume en ligne à l'aide d'instruments de mesure de densité de courant.
