Theoretical study of the change in the concentration of demulsifier due to the phase ratio in the product

Abstract

Phase separation in the oil gathering and transportation system is a significant process since it is determined by the preliminary stability of oil emulsions and the total energy expended in their destruction. The redaction of the emulsion stability requires the introduction of a demulsifier. The main requirement for demulsifier reagents used in the oil industry is to achieve the most complete destruction of emulsions. The degree of destruction of an emulsion depends to a large extent on the amount of the dosed demulsifier reagents and the degree of its reactivity. In the fields, there is often an unevenness of reagent loosening. Effective emulsion separation requires the establishment of a stable dosage determined by laboratory tests. There is an analysis of the variation in concentration of the demulsifier fed into the collection system as a function of the fluid flow properties. The paper also considers determining the change in concentration of the demulsifier fed into the collection system. Practical data show that the lower the concentration of the demulsifier, the higher the proportion of the dispersion phase (water) and the higher the viscosity of the dispersion medium (oil).
