  • Monitoring hydrocarbons in Bilge water - Case study

    The Situation Various processes onboard ships, such as machinery wash-down, maintenance, and leakage, generate oily wastewater. This contaminated water flow collects in the bilge of the ship. Marine diesel, lubricating oils, grease, as well as other contaminants may be present in bilge water. The bilge water is discharged overboard, with oil and grease concentrations in the discharged ...

  • Guide To Coolant In Oil Test Methods

    Liquid cooled engines and rotating equipment use glycol based coolants because of their excellent heat transfer abilities. However, glycol based coolants are not desirable at all in lubrication oil itself – Coolant ingression to the lubricant is a particularly nasty contaminant for the variety of damage it can cause. Glycol coolants break down in the high temperature engine environment, ...

  • Solution blooming for fracking spills?

    Blooming salts may clean up after brine spills North Dakota's oil boom can have a salty side-effect. Wastewater from oil drilling and hydraulic fracturing – or fracking – is often laden with salts and can spill, contaminating soils. In 2014, for example, 42 such brine spills per week, on average, were recorded in North Dakota. Brine spills introduce so ...

  • Fabrication of polysiloxane-modified polyurethane sponge as low-cost organics/water separation and selective absorption material

    Through sol-gel and dip-coating processes, commercial polyurethane sponge modified by polysiloxane was fabricated under low temperature (60 °C) and atmosphere. The contact angle of the obtained polysiloxane/polyurethane sponge is 145 ± 5°. Hence, the polysiloxane/polyurethane sponge could float on water and selectively absorb organics from the surface of the water, indicating simultaneous ...

  • Effect of bank curvatures on hyporheic water exchange at meter scale

    The micro-topography feature of a riverine system is a controlling attribute to induce the change of patterns and magnitudes of hyporheic water exchange. The study aims to determine how hyporheic water exchange is affected by the bank curvatures of test points at meter scale. A one-dimensional heat steady-state transport model was applied to determine patterns and magnitudes of vertical ...

  • Case study - Nigeria crude oil in soil site

    Safic Technologies, Ltd. - Port Harcourt A pilot study was conducted testing soil samples collected from a pipeline spill. Split samples were sent to Sitelab for EDRO analysis and results were the same. Samples were also sent to a Nigerian lab and a highly reputable lab in the United States for confirmation. After testing the samples a second time, the American lab got better results. ...

  • Biosurfactant produced by a Rhodococcus erythropolis mutant as an oil spill response agent

    Biosurfactants have been considered as superior alternatives to currently used surfactants as they are generally more biodegradable, less toxic, and better at enhancing biodegradation. However, the application of biosurfactants is limited by the availability of economic biosurfactants and the corresponding producers that can work effectively. Hyperproducers generated by metabolic engineering ...

  • Effects of chemical dispersant and seasonal conditions on the fate of spilled oil – modelling of a hypothetical spill near Saint John, NB

    The proposed Energy East pipeline project has raised concerns about potential oil spills in Saint John, New Brunswick. While environmental conditions could pose challenges for using mechanical recovery methods if a spill occurs, chemical dispersant could be an alternative. However, the application of chemical dispersant in shallow water and costal zones remains an issue of debate. Furthermore, ...

  • Detection of polycyclic aromatic hydrocarbons (PAHs) in raw menhaden fish oil using fluorescence spectroscopy: Method development

    Raw menhaden fish oil was developed for biomonitoring polycyclic aromatic hydrocarbons (PAHs) using fluorescence spectroscopy. Menhaden (Genus Brevoortia) were collected from Delaware Bay, NJ (DBNJ), James River, VA, Vermillion Bay, LA (VBLA) and Barataria Bay, LA (BBLA) in 2010 and/or 2011. Barataria Bay, LA received heavy oiling from the DeepWater Horizon (DWH) oil spill. Method development ...

  • What’s the most important measure of success?

    As 2014 comes to a close and we prepare to celebrate Ensia’s second anniversary this coming February, I wanted to take a moment to reflect on the journey we’ve been on over these past couple of years. In my role as Ensia’s director, I often meet with potential partners, supporters, thought leaders and others. More often than not, one of the first questions I’m ...

  • Enhancing the hydrophobicity of mangrove bark by esterification for oil adsorption

    Oil spills generally cause worldwide concern due to their detrimental effects on the environment and the economy. An assortment of commercial systems has been developed to control these spills, including the use of agricultural wastes as sorbents. This work deals with raw and modified mangrove barks (Rhizophora apiculata), an industrial lignocellulosic waste, as a low cost adsorbent for ...

  • Portable IR Analyzers Provide Petroleum & Wastewater Industries with Accurate Oil Content Measurements

    Fixed filter infrared (IR) analyzers have been used to test oil levels in produced water on off-shore and on-shore drilling platforms for well over 45 years. U.S. EPA methods 418.1 and 413.2 were used extensively on a worldwide basis until the Montreal Protocol called for Freon (the solvent used in the analysis) to be phased out. Infrared analysis using tetrachloroethylene (perchloroethylene) is ...
