  • Experimental investigations on diesel engine fuelled with methyl esters of cotton seed oil

    In this investigation, cotton seed methyl ester (CSME) was prepared by transesterification using potassium hydroxide (KOH) as catalyst. The engine performance was analysed with different blends of biodiesel and was compared with neat diesel. It was concluded that the lower blends of biodiesel are closer to diesel as far as thermal efficiency is concerned. In the lower blends, the brakes specific ...

  • Reaching Euro VI emissions limits

    The requirements of low and lowest detectable exhaust analysis has prompted Eco Physics to launch a broad range of analyzers for NO/NOx detection. Emissions tuning is one of the targets of the EURO VI regulations as well as US EPA 2010, which are: Reduction of Particulate Matter (PM) and reduction of Nitrogen Oxides (NOx). In the past 15 years – since the first European regulation for exhaust ...

  • 80-95% NOx Reduction SCR without the use of urea

    A new, patented catalyst developed by scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory that can reliably and economically reduce between 95 percent and 100 percent of the nitrogen oxide (NOx) emissions from diesel fueled engines has been licensed to Integrated Fuel Technologies, Inc. (IFT), a Kirkland, Wash.-based start-up company. IFT plans to integrate the ...


  • Exhaust Gas Treatments for NOx Reduction to Add to Global Warming

    The enforcement of year 2007 stringent emission norm for reduced NOx reduction/oxides of nitrogen gases from the diesel exhaust and the after treatment to reduce them will add to global warming by several fold according to renowned engine combustion kinetics, emission control process expert and inventor -Mr.Srinivasan Gopalakrishnan, Hydrodrive Systems & Controls Pvt. Ltd, India. His invention ...

  • NOx in Non-Utility Industries - Part II - Control options and monitoring methodology

     This the second in a two-part series. Part I, which appeared in our June 2001 issue focuses on air emission origins of nitrogen oxides (NOx) in non-utility industries. Choice of the NOx control technology is dependent on many factors, including regulatory requirements, technical feasibility, cost and public perception. Figure 1, compiled based on publications [1-5], presents a summary of ...


  • Staten Island Ferry, Alice Austen, SCR demonstration project case study

    In December of 2003, the Port Authority of New York and New Jersey (PANYNJ) undertook a project to retrofit the Staten Island Ferry vessel, Alice Austen, with selective catalytic reduction (SCR) and diesel oxidation catalyst (DOC) exhaust aftertreatment.  Alice Austen was selected for the first SCR demonstration project as it is one of ...

  • Midwest contractor turns pollution into profits - Fred Weber

    Ed Moss knows a good thing when he sees one.  When Moss, maintenance manager for the major construction firm of Fred Weber, Inc., first tried out a fuel-saving device on one of the company’s diesel engines, something clicked right away.  Those first test results, conducted on an engine loading limestone at a mine, showed a fuel savings of 33 per cent, Moss said. What’s more, when his ...

  • Air as Clean as the Driven Snow

    While California is the most populated state in the nation, it is also home to some of America’s most natural and pristine wilderness and recreation areas. One such venue is the Snow Summit Ski Resort in Big Bear Lake.  Situated just over two hours from Los Angeles, Snow Summit is a fullservice winter resort that opened in 1952 and operates an average of 142 days a year. ...

  • Going green means saving the green for Midwestern contractor
