Chemical demulsification is widely used in the petroleum industry to remove water from crude oil all over world. In this work, relationship between rheological properties of oil/water interfacial film and emulsions was investigated. The results showed that elastic modulus critical factor for dehydration ratio, high ratio when demulsifiers reduced oil–water a certain extent (below 5 mN/m). Correlations equilibrium tension, dynamic loss were also no correlation tension (IFT), modulus, ratio....
Demulsification efficiency with alternating hydrophobic blocks of the polyether is investigated by dissipative particle dynamics.
In the present work, effects of shear fields on aggregation asphaltene molecules in heptane were investigated by means dissipative particle dynamics simulations. The geometries aggregates without studied, and simulation results provide an interpretation experimental microscopic level. also accessing radial distribution functions, spatial orientation correlation radii gyrations. We show that can destroy conformational order damaging organized structure isolating asphaltenes. As radius...

High internal phase emulsions (HIPEs), in which the dispersed water exceeds 70%, play a critical role enhancing oil recovery through situ permeability modification. However, their stability remains major challenge due to frequent inversion and coalescence. In this study, formation stabilization mechanisms of water-in-oil HIPEs were investigated using multiscale modeling approach that combines dissipative particle dynamics (DPD), molecular (MD), density functional theory (DFT). Fourteen types...
Abstract This paper proposes a process for fabricating poly-dopamine-silk fibroin sponge (PDA-SF) by using dopamine self-assembly and coating the skeleton of silk sponge. The PDA-SF was characterized SEM, TEM, XPS, XRD FT-IR. It found that exhibits sheet structures with pore size 60 ± 20 μm poly-dopamine adhered to surface pure through noncovalent bond forces. With hierarchical porous structure, derived provides fast flow channels abundant active sites, which will benefit diffusion removal...
Herein the adsorption characteristics of zwitterionic dye pollutant Rhodamine B (Rh+B–) on a g-C3N4 surface were investigated by both an attenuated total reflection spectroscopy (ATRS) experiment and molecular dynamics simulation (MDS). For experimental investigation, was coated silica optical fiber (SOF) to fabricate film. According ATRS response, thermodynamics results in situ obtained evaluated. The isothermal Langmuir model used calculate equilibrium constants (Kads) energies (ΔGads) for...
ABSTRACT Iron oxide nanoparticle has been successfully modified by polyacrylamide and the magnetic nanoparticles (PMMNs) were applied to remove Cr(VI) in wastewater. The vibrating sample magnetometer (VSM) spectra indicated large saturation magnetization superparamagnetic property of PMMNs. This made iron easily separate with liquid phase. Scanning electron microscope (SEM) results showed that both synthesized PMMNs nanoscale. Batch adsorption studies had carried out determine effect pH,...
