Oil-gas–water three-phase slug flow characterization and flow rate metering is an important issue highly related to the production safety and efficiency in petroleum industries. In this article, to ...

In this paper, we propose a multivariate multi-scale incremental entropy (MMIE) method to analyze the complexity of oil-water two-phase flow. Firstly, we verify the feasibility of MMIE by typical time ...

A salt-free cationic and anionic (catanionic) surfactant system was formed by mixing a double-tailed di-(2-ethylhexyl) phosphoric acid (DEHPA, commercial name P204), which is an excellent extractant ...

Quasi-ternary dextran-water-polyethylene glycol (D-W-PEG) systems can undergo a segregative phase transition from a homogeneous to two-phase state with one phase enriched in dextran, the other in PEG, ...
