APPARATUS AND METHOD FOR CHARACTERIZING AN INTERFACIAL PROPERTY OF A DISPERSION

摘要

An improvement in a PVT apparatus, which improvement includes a fluid pathmodel having a fluid path and a sampling section, wherein the depth of thefluid path within the sampling section is substantially uniform and is lessthan about 100 ~m. The apparatus may be configured to provide a micron-scaleslim tube which may be used in a manner similar to a conventional slim tubeapparatus. A method for characterizing an interfacial property of a dispersionsuch as, for example, miscibility of a first fluid and a second fluid as afunction of pressure. The method includes collecting sets of transmittanceimages representing transmittance of electromagnetic radiation through thedispersion, generating values of a general interfacial property factor fromthe transmittance images, and characterizing the interfacial property usingthe values of the general interfacial property factor.
