Investigation of Oil-in-Water Emulsions Treatment by Crude
Abstract Investigation of Oil-in-Water Emulsions Treatment by Crude Oil Degrading Bacteria and Coagulation with Cationic Polyacrylamide. Milad Parhamfar, Zeynab Bayat, Maryam Parhamfar, Mehdi Hassanshahian and Samaneh Sadat Hosseini. Background: Oily wastewater which is released from different industries is one of the most common pollutants.
Emulsions of oil droplets in water but more typically water droplets in oil are common in the production, transportation, and refining of petroleum and related products. Emulsions of water in petroleum or petroleum-derived liquids can be stabilized by a variety of surface-active compounds and components present in petroleum and also with which petroleum comes into contact.

Demulsification of Water-in-Crude Oil Emulsions
Microwave radiation to promote the destabilization of water-in-crude oil petroleum emulsions is already an alternative technology for heating. Recent studies have suggested that microwave heating is more effective than conventional heating. This study assessed the following effects on the demulsification process: the aging of emulsions for the two types of heating (microwave and conventional
Seeking highly efficient, rapid, universal, and low-cost demulsification materials to break up the crude/heavy oil-in-water emulsion and emulsified oily wastewater at ambient conditions has been the goal of the petroleum industry. In this work, an amphiphilic material, graphene oxide (GO) nanosheets, was introduced as a versatile demulsifier to break up the oil-in-water emulsion at room
Stabilization of Water in Crude Oil Emulsions. Part 2
Conventional wisdom says that asphaltene adsorption at the water−oil interface is the main source of high stability of W/O emulsions in petroleum systems. Although this approach is partiallly correct, it does not explain all experimental data. High-resolution Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometry data show that the composition of the surface material collected
Two oil sand froth treatment methods are investigated: 1) dilution with an aromatic solvent followed by centrifugation (AS Method); 2) dilution with a paraffinic solvent followed by gravity settling (PS Method). The effectiveness of the methods is assessed in terms of bitumen recovery and the water content in the recovered diluted bitumen.
Viscosity of Water-in-Oil Emulsions from Different
Water-in-oil (W/O) emulsions are very common in oil field operations and are formed as a result of energy input from turbulence caused by the flow in the production pipelines, pumps, and valves. Understanding emulsion rheological behavior is crucial to deal with flow assurance issues. This paper presents and discusses a series of rheological experiments carried out with synthetic emulsions
Water-in-oil emulsions were prepared by mixing crude oil and water (4:1 v/v) to obtain 20% (v/v) water content. The emulsification was carried out using a homogenizer at a rate of 10000 rpm for 5 minutes to get a stable emulsion with droplets ~10 μm in diameter. About 10 mL of emulsion sample was prepared and preheated to 70 °C.
CHEMICAL DEMULSIFICATION OF MODEL WATER-IN-OIL EMULSIONS
Abstract. The demulsification of model water-in-oil (w/o) emulsions containing 1% wt. water by [Omim][PF 6] and Aliquat ® 336 ionic liquids (IL) as demulsifiers was investigated in batch mode at different temperatures (30, 45 and 60 °C) and demulsifier concentrations (2.5×10 ‒3, 1.2×10 ‒2 and 2.9×10 ‒2 mol L ‒1).The model oil is a mixture n-heptane/toluene (70/30% wt.) with 1% wt
The formation of water-in-oil emulsions during crude oil production is a problem for crude oil industry. Until now, the most common way of separating water from crude oil is by using chemical demulsifiers [1].Although chemical demulsifiers are widely used in crude oil industry, they are not very efficient [2].Until recently, ultrasonic irradiation was considered as an efficient method to
