  • Exhaust Products - Case Study

    Project Background High radiant heat emitted from the muffler shell can cause grass browning*, engine vapor lock**, fires and excessive bumper and shroud temperatures.  Muffler temperatures started increasing an engine OEM's created leaner burning engines to meet the EPA Tier 1 Regs issued back in 2001.  The engines continue to become increasingly leaner burning to meet Tier ...

  • VOC Abatement Technology Saves on Operating Costs for Aerospace Paint Finishing

    For over 10 years, a Canadian aircraft manufacturer has saved over $500,000 annually in fuel and electricity consumption by using Munters rotor concentrators to control solvent emissions from its facility’s paint booths. Before purchasing Munters equipment in 2002, the manufacturer struggled with the inconvenience of having their aircraft systems flown to be painted in subcontracted paint ...

  • How can lead be so crucial, but also so toxic?

    Why is everyone talking about lead? Not long ago, like so many historic buildings in the UK, a local parish church near to where I live had the lead stolen from its roof.  Sadly, this is not so unusual and all the more distressing in this case, both because it holds special memories as the church where my wife and I were married, and also because the lead was stolen during heavy ...

  • Superheated water pretreatment combined with CO2 activation/regeneration of the exhausted activated carbon used in the treatment of industrial wastewater

    This paper examines a novel method of regenerating saturated activated carbon after adsorption of complex phenolic, polycyclic aromatic hydrocarbons with low energy consumption by using superheated water pretreatment combined with CO2 activation. The effects of the temperature of the superheated water, liquid–solid ratio, soaking time, activation temperature, activation time, and CO2 ...

  • Hot weather on its way ... Check the condition of your cooling tower

    The approach of summer is a good time to check the performance and, more importantly, the physical condition of your cooling towers. After all, it’s easier to repair a tower when weather conditions don’t put a strain on its cooling capacity. A cooling tower passes air over tiny droplets or the exposed surface of a water film. In both cases, a small amount of water is vaporized, ...

  • High Rate Biological Odour Control Demonstration for Biosolids Exhausts

    Abstract Biorem has successfully demonstrated its high rate odour control system for biosolids exhausts at Ashbridges Bay sewage treatment plant in Toronto, Ontario. The demonstration used XLD™, a biofiltration media engineered specifically for biosolids odours. The system has achieved 95% odour removal in less than 20-s Empty Bed Residence Time (EBRT) despite high concentration of ...

  • Application of PdCe-HMOR catalyst as NOx CH₄-SCR system for heavy-duty vehicles moved by natural gas

    Abstract In this work a cobalt-free zeolite-based catalyst formulation is proposed for NOx CH4-SCR towards a commercial application of after-treatment system for heavy-duty vehicles moved by natural gas (lean-gas burn engines). PdCe-HMOR catalyst was characterised by H2-TPR, DRS UV–Vis and TEM/EDS. The effect of [CH4]/[NO] in the ...

  • Catalytic NO oxidation in the presence of moisture using porous polymers and activated carbon

    Abstract NO oxidation catalyzed by porous materials is difficult to implement under industrial conditions because moisture in combustion exhaust streams blocks oxidation sites, decreasing NO conversion. In this work, hydrophobic cross-linked polymers are tested as NO oxidation catalysts to overcome these negative impacts associated with moisture. Although activated carbons (ACs) ...

  • Case study - ETO sterilizer abatement

    OVERVIEW Product sterilization companies are generally required to utilize a pollution control device for treatment of exhaust gases from their aeration room and sterilization chambers.  In the United States, they need to be in compliance with NESHAP (National Emission Standards for Hazardous Air Pollutants) regulations that dictate a 99% destruction efficiency of EtO (Ethylene ...

  • Experimental method for marine engine’s emissions analysis

    Abstract The world is considering various solutions to reduce exhaust emissions, the use of alternative fuels and the development of more efficient marine engines. IMO the company gave guidance for future borders of individual exhaust components, taking into account a variety of applications and conditions for the operation of marine engines. Engine ...

  • Case study - Engine test cell exhaust: RTO

    Overview A Mid-western outboard engine manufacturer bought a three year-old plant for the production of its marine engines. When finished, the engines are removed from the assembly line and run for quality control. The 25,000 SCFM of exhaust from testing contains volatile organic compounds (VOCs) that require regulatory compliance. Also within this exhaust is a great deal ...

  • Thank You All for the Success of MEXA-7000

    The MEXA-ONE, our new Motor Exhaust Gas Analyzer launched in 2012, has become our core product superseding the MEXA-7000 with a surge in the number of shipments since the beginning of 2014. The MEXA-7000 had evolved continually over the nineteen years since its introduction in 1995 to respond to the significant changes that took place in emission regulations, types of fuel and new technology in ...

  • Combined bio-regeneration and ion-exchange system for perchlorate removal

    In order to prove that perchlorate-laden resins could be bio-regenerated through direct contact with perchlorate-reducing bacteria (PRB), a combined bio-regeneration and ion-exchange (IX) system was operated. Two kinds of perchlorate-laden resins, nitrate-selective A520E and perchlorate-selective A530E, were successfully regenerated by PRB cultivated under anaerobic conditions. The ...
