Some Key Problems Encountered for Demulsifier Research

Abstract:

Main reasons, of which viscous crude emulsion and chemical flooding emulsion are difficult to demulsify, is that their compositions and structures have tremendous differences to water flooding emulsion. To resolve main difficulties encountered in demulsifier research today, such as demulsification of viscous crude oil emulsion, demulsification of chemical flooding emulsion, some research value routes, such as increasing aromaticity, molecular weight and branch degree of demulsifier molecule, and leading double-function groups meeting W/O type and O/W type emulsion and groups with alkyl carbon number matching equivalent alkyl carbon number of the crude oil into demulsifier molecule, were suggested according to demulsification mechanisms and their emulsion characteristics, and action mechanisms of the above-mentioned research routes were elaborated at the same time.
