Emulsification of pyrolysis oil produced from plastic waste has been experimented. The employed cascade heating steps and heating rates pyrolysis process provides 80% product yield using waste plastic or recycles HDPE pellets as a raw material. Water-in-oil emulsion is produced ultrasonically and mechanically with Span80 as a surfactant. The emulsion stability was assessed by water droplet size and visual observation of any phase separation. An ultrasonic mixer is found to be more effective than mechanical homogenizer in terms of homogenous stability to emulsify plastic oil with water. For emulsion with 10% water by volume, the emulsion is observed to be stable for up to 24 hours after mixing.

A state-of-the-art, portable dispersion characterization rig (P-DCR) is used to investigate the effect of nanoparticles (NP) on oil-water emulsion formation and stabilization. Spherical silica NP of different wettabilities were used to investigate their effect on separation kinetics of solid stabilized emulsions in terms of solid particle concentration, wettability, initial dispersion phase, water-cut, and shearing time. The main findings of the study include the following: NP, even at concentrations as low as 0.005% or 0.01% (by weight), can significantly increase separation time of oil/water emulsions from a few minutes to several hours or even days. The P-DCR is recommended as an effective inline tool to measure emulsion stability in the field.

Water In Oil Emulsion

In this paper, the EDM performance of water-in-oil (W/O) emulsions dielectric with different surfactant concentration is investigated by correlated to its physical properties, such as viscosity and droplets size, which is predominantly determined by the surfactant concentration. Experimental results show that the stability of the W/O emulsions increases with increasing surfactant concentration, whereas the EDM performance deteriorates with increasing surfactant concentration. So, taking a comprehensively consideration of the emulsion stability and EDM performance, the concentration of surfactant must be appropriately selected.
