Chemical characterization of oil and water accommodated fraction (WAF) at different temperatures
Results in Engineering, 2022 In this work, the formation and the chemical composition of Water Accommodated Fractions (WAFs) of Intermediate Fuel Oil 180, Naphthenic North Atlantic, and Marine Gas-Oil oils were studied at different temperatures (between 5 and 25 °C) with and without

Chemical Engineering of Polymer Dispersions
CHIMIA, 2001 The research activity on dispersed polymers – polymer particle size from tens of nanometers to hundreds of microns – carried out at ETH in our group is reviewed with a brief summary of the various projects currently in progress. These have been organized into two main categories: Polymer Reaction Engineering, where polymerization reaction and

On the chemical potential of nanoparticle dispersion [PDF]
Physics Letters A, 2020 Abstract Understanding of the mechanism describing the chemical potential of nanoparticle dispersions, whether from modelling or experimental perspectives, is missing in the literature. As nanofluids are widely used in engineering applications, predicting material properties correctly needs a correct formulation for their behaviour.

Dispersing Crude Oils of Varying Viscosities Using a Food-Grade Dispersant [PDF]
, 2020 The mitigation of crude oil spills in the ocean is generally done using chemical dispersants, which convert the oil slick into small droplets. These dispersants are mixtures of surface-active molecules (surfactants) dissolved in a solvent.

Chemical dispersants and quantification textural fractions by Bouyoucos and pipette methods
Acta Agronómica, 2015 An adequate individualization of particles is required for a correct granulometric analysis in order to quantify the real percent composition of particles in the soil. The aim of this study was to compare the percent of granulometric fractions determined

Influence of Scale on Chemical Dispersivity in Geomedia
Procedia Computer Science, 2012 AbstractChemical dispersivity is a common parameter needed for pollutant fate and transport models in geomedia environments. This study estimated the effect of distance on dispersivity measured in columns using X-ray computed tomography. Columns containing natural and homogeneous media were evaluated.

Microbial Functional Responses in Marine Biofilms Exposed to Deepwater Horizon Spill Contaminants
Frontiers in Microbiology, 2021 Marine biofilms are essential biological components that transform built structures into artificial reefs. Anthropogenic contaminants released into the marine environment, such as crude oil and chemical dispersant from an oil spill, may disrupt the ...
