A New Semiautomatic PVT Apparatus for Characterizing Vapex Systems

摘要

Knowledge of fluid properties is critical to the design of Vapex projects and other enhanced oil recovery processes that use solvent vapor extraction,yet very few pertinent data exist in the published literature.This paper describes a new apparatus for the efficient and accurate measurement of the physical and phase behaviour properties of mixtures of heavy oils and solvents such as propane and butane.The apparatus combines advanced capabilities that make it superior to conventional designs:The automated functions improve the speed at which the data are acquired and reduce operator error.
