Dispersants are among a number of options available to oil spill responders. The goals this technique remove from surface waters in order reduce exposure surface-dwelling organisms, keep slicks impacting sensitive shorelines, and protect responders volatile organic compounds. During the Deepwater Horizon response, unprecedented volumes dispersants (Corexit 9500 9527) were both sprayed on airpla...

Abstract Production activities of petroleum have resulted in extensive environmental pollution, due to accidents, leaks, and oil spills during these activities. Gathering Station is one production facility at the field that serves as a gathering place for several liquids produced from wells measure flow rate. Wastewater still contains oil, so before being discharged into water bodies should be ...

Nano particles of zinc borate were obtained by homogeneous precipitation method which is based on dissolving in ammonia and precipitating it as nano slow evaporation ammonia. The synthesized borates characterized advanced analytical techniques. Zinc used a lubricant additive to spindle oil having Span 60 dispersant. well dispersed shown optical microscopy the oils. Four ball tests lubricants in...

We illustrate in this paper the interest of cryo-field-emission gun scanning electron microscopy (cryo-FEGSEM) to investigate the stability of alumina suspensions. The stability is investigated through viscosity, zeta potential, total organic carbon measurements, and cryo-FEGSEM observations. We focus on two examples: the effect of the quantity of ammonium polyacrylate as dispersant and the eff...

The purpose of this study was to evaluate the physical properties and hydration evolution of calcium aluminate cement (CAC) compositions containing an advanced dispersant. The compressive strength, dimensional change, apparent porosity and quantitative X ray diffraction analysis (XRD) of the cement pastes were carried out over 1-15 days of curing (with the samples immersed in distilled water) a...

Titania is one of the most important white pigments currently used in the world with a total annual production of about 6 million [1]. Titania pigment slurry properties are very important for consumer industries such as paints, papermaking and plastics; if aggregates are present, the end-use properties including gloss, brightness, colour hue, opacity and storage stability will be highly affecte...
