  • Additives for fuel economy: a modern view

    Fuel additives. A private car doesn’t just give you the pleasure of a quick and comfortable ride, but it also requires everyday expenses for maintenance, and the biggest expense is the cost of fuel. The question of saving on fuel is very relevant. The Internet offers many tips. One of the ways to save fuel is to use special additives. But experience shows that these additives have both ...

  • While Oil Prices are Down, Get Up on Compliance

    It’s no secret that the oil and gas industry has taken a hit lately, with per-barrel prices dipping to as low as $27. The saturated market and low prices have many companies putting a hold on drilling. While no one in our industry likes dipping oil prices, there are two things you can do to weather the storm until those prices take a (much welcomed) upward turn: Stay up to date on ...


  • Studies on behaviour of a DI diesel engine fuelled with bio oil biodiesel emulsions

    This paper discusses the results on the use of Jatropha methyl ester (JME) - Wood pyrolysis oil (WPO) emulsion as an alternative fuel in a compression ignition (CI) engine. Three different emulsions were prepared by adding WPO in 5%, 10% and 15% by volume with JME 95%, 90% and 85% by volume respectively using a surfactant Span 20 at 4% on volume basis. The engine behaviour in terms of the ...

  • Where Did These New Quality Assurance Requirements for Opacity Monitors Come From?

    U.S. EPA promulgated the long awaited ‘‘Quality Assurance Requirements for Continuous Opacity Monitoring Systems at Stationary Sources’’ used to demonstrate continuous compliance with opacity standards specified in new source performance standards (NSPS).  This has an effective date of November ...

  • Utilisation of pulverised coal fly-ash as filler and rice straw as fibrous raw material for manufacturing of special grade paper

    This innovative research study is based on utilisation of two solid waste materials, pulverised coal fly-ash and rice straw for manufacturing of laminate base paper. Fly-ash can prove to be a very good filler for laminate grade coloured base papers and other specialty papers where very high opacity is sought but whiteness is not important. The paper samples with 22% filler have opacity of 99.6% ...

  • An experimental investigation on the performance, emission and combustion characteristics of preheated calophyllum inophyllum linn oil (honne oil) fed DI diesel engine

    The present work examines the use of a non–edible vegetable oil namely honne oil, a new possible source of alternative fuel for diesel engine. The use of honne oil (unheated and preheated) in an agricultural direct injection (DI) diesel engine has not been reported in the literature. The high viscosity of honne oil can be reduced by preheating (preheated to 60°C). The effect of ...

  • Effect of injection timings on the performance, emission and combustion characteristics of DI diesel engine running on Calophyllum inophyllum linn oil (honne oil)

    The present work examines the use of a non–edible vegetable oil namely honne oil, a new possible alternative fuel for diesel engine. A direct injection (DI) diesel engine typically used in agricultural sector was operated on neat diesel (ND) and neat honne oil (H100). Static injection timing (start of static injection timing) was changed to study the performance, emission and combustion ...

  • Performance of a direct diesel engine using aviation fuels blended with biodiesel

    In this study, jet fuel (JF) and railroad fuel (D2) with SME blends (5%, 20%, 50%) were used in a four–cylinder, naturally aspirated, direct (DI) diesel engine. The engine was operated under full load and tested at various speeds to determine the engine's performance and exhaust emission characteristics. The experimental results show that as the SME ratio of the fuels increases, the break ...

  • Triiodophenyl acrylate–based microbeads find important use in the medical field

    Preparation of polymeric micro– and nanoparticles has significantly become an effective approach for achieving efficient drug targeting to tumour tissues. A promising solution could be the use of a radio–opaque polymeric system carrying iodine groups. In this context, radio–opaque polymeric microparticles based on methyl methacrylate (MMA) and an 2,4,6–triiodophenyl acrylate (TIPA) were ...

  • Multi-pollutant control creates fuel options for whiskey distillery

    The distillation of fine whiskey requires the application of appropriate amounts of heat in the form of steam. The generation of that steam can come from multiple sources of energy. The Wild Turkey Distillery located in Lawrenceburg, KY has utilized an EISENMANN Wet Electrostatic Precipitator Dual Field (WESP- 2F) to provide multi-pollutant air pollution control on the plants new biomass fired ...

  • Environmental impact of using biodiesel as fuel in transportation: a review

    The environmental pollution and global warming associated with the use of fossil fuels, has forced a search for alternative fuels in transportation. This paper presents a review of the use of biodiesel in CI engines and its environmental impacts. There is a significant reduction in the emission of unburned hydrocarbons, polyaromatic hydrocarbons and soot, particulate matters, carbon monoxide, ...

  • Marine Industry experience with Aalborg Industries

    Port Authorities and Governing Bodies state that a ship cannot emit smoke of >20% opacity for more than 3 minutes when in port. The IMO set similar limits for on-board incinerators. The DSL-220 Opacity Monitor has been used successfully to measure smoke emissions from diesel engines, incinerators and boilers on board ship ensuring that environmental concerns are ...

  • An analysis of extinction coefficients of particles and water moisture in the stack after flue gas desulfurization at a coal-fired power plant

    Two important factors that affect in-stack opacity—light extinction by emitted particles and that by water moisture after a flue gas desulfurization (FGD) unit—are investigated. The mass light extinction coefficients for particles and water moisture, kp and kw, respectively, were determined using the Lambert-Beer law of opacity with a nonlinear least-squares regression method. The ...

  • Comparison of four methods to assess biofilm development

    Two nondestructive methods of biofilm quantification (optical density via a flatbed scanner and biofilm thickness) have been evaluated and compared to two destructive methods (Crystal Violet staining after biofilm disintegration and dry weight). The methods were tested on biofilms that developed on a modified rotating biological contactor (RBC) that was inoculated with urban wastewater and fed ...

  • Israel and the bomb

    In spite of its policy of ambiguity, Israel's nuclear military capability is universally admitted. This raises the question of the underlying doctrine and the function played by the bomb in the political-military relations between Israel and its neighbours since the end of the 1950s. This paper shows that instead of contributing to deterrence, the bomb has been irrelevant (at best) or ...

  • Assessment of bagging operators exposure to with pvc airborne particulates

    The hazard potential of airborne particles is dependent on the mass concentration as well as the particle size. Particle size determines the deposition site within the respiratory tract and the subsequent health effects. Particle-size is considered from two viewpoints: The sizefraction most closely associated with the specific health effect, and the mass concentration within that size fraction. ...

  • Chemical Plant Desulfurization

    KRONOS’ facility in Leverkusen, Germany produces titanium dioxide, the most important material used by the paints and plastics industry for whiteness and opacity. When new German guidelines set maximum emission limits for SO2 in 1989, KRONOS was required to eliminate the COS from the off-gas at their titanium dioxide production facility to meet the new requirements.Complicating this application, ...
