Effects of liquid-liquid interfaces on flow of oil-in-water emulsions in a capillary tube

Chisato Tajima et al.

Summary: We studied the flow of oil-in-water emulsions in capillary tubes of various sizes and oil droplet volume fractions. The front position of the flowing emulsions can be accurately described by a power law formula. The ratios of the oil-water interfacial area to water volume and water-wall interfacial area to water volume are important factors in describing the front position. The role of liquid-liquid interfacial area is also discussed.

Upcycling Waste Pine nut Shell Membrane for Highly Efficient Separation of Crude Oil-in-Water Emulsion

Haoyu Li et al.

Summary: The discharge of oily sewage and frequent oil spills have caused serious harm to human production, life, and the ecological environment. The presence of surfactants in water makes oil-water mixtures form oil-in-water emulsions which are difficult to separate using traditional methods. The oily wastewater containing water-soluble pollutants like dyes and heavy metal ions also poses great harm to human health and the environment. A cost-efficient and environmentally friendly underwater superoleophobic pine nut shell membrane (PNSM) was prepared, which allows the separation of oil-in-water emulsion and adsorption of dyes and heavy metal ions. The PNSM also showed excellent toughness and flexibility, making it a promising candidate for multifunctional oily water remediation.
