Terahertz characterization and evaluation of crude oil emulsions
Abstract
Experimental researches including emulsion's stability, type identification and fluid interface detection have been carried out by terahertz technology in this paper. Stabilities of three crude oil emulsions and the demulsification process have been monitored by real-time terahertz spectroscopy. Meanwhile, O/W emulsions rather than W/O emulsions demonstrate characteristic absorption peaks at special frequency. These characteristic absorption peaks can be used to determine the concrete type of crude oil emulsions. The results will provide experimental foundation and data preparation for terahertz applications in quick quantitative evaluation and identification of crude oil emulsions.
