  • Case study - Engine cell exhaust: Catalytic oxidizer

    Overview Endurance testing of outboard motors for boats has typically been done in lakes and sometimes on barges. This testing was time consuming, presented logistic problems and removed the testing from the R & D department and the factory. When a company in Oklahoma decided to build their own endurance test cell area, the Environmental Protection Agency required them to control the ...

  • Composition and textural properties of soot and study of their oxidative elimination by catalytic process

    Diesel soot and reference carbon black samples have been characterised by analysis of the organic compounds fraction and determination of textural characteristics (specific area). The potential to eliminate such carbonaceous particles has been investigated using a Cu/ZrO2 solid catalyst promoted by potassium additives. The reactivity of soot samples depends on the organic compounds content. In ...

  • Modification of thermal and oxidative properties of biodiesel produced from vegetable oils

    Trans esterification of three vegetable oils, sunflower oil, linseed oil and mixed oils as; sunflower-soyabean and olein were carried out using methanol, and potasium hydroxide as catalyst. The methyl esters of the corresponding oils were separated from the crude glycerol and characterized by physical-chemical methods to evaluate their thermal ...

  • 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 ...

  • 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 ...


  • 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 ...


  • The emission characteristics of a compression ignition engine operating on castor oil methyl ester

    Diesel vehicles are a major form of transportation, especially in developing countries. Recent concerns over the environment, increasing fuel prices and the scarcity of its supply have promoted interest in the development of alternative sources of petroleum fuels. In this investigation, castor oil methyl ester was prepared by transesterification using potassium hydroxide (KOH) as a catalyst and ...

  • 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 ...

  • 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 ...

  • 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. ...

  • Common Treatment Technologies for Nonhalogenated VOCs

    Soil vapor extraction (SVE), thermal desorption, and incineration are the presumptive remedies for Superfund sites with nonhalogenated VOC-contaminated soil. Because a presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site, the presumptive remedy approach will accelerate site-specific ...

  • Dredging Up Power

    Caterpillar Marine was selected to power three 3500 m³ trailing suction hopper dredgers for the Jan De Nul Group with Cat 3500E IMO III and EPA Tier 4 certified engines. Cat said the 3500E incorporates selective catalyst reduction (SCR) after-treatment technology with closed-loop NOx sensing and application optimized performance for minimized owning and operating costs. “Embedded ...
