  • Meeting Emission Control Through Improved Actuation

    Reducing fugitive emissions, particularly methane, is a major priority in the fight against climate change. Although valves and actuators have been the focus for reduction efforts because valve leakage accounts for more than half of total fugitive emissions, the problem is mainly old valves that weren’t designed using the latest materials and technologies. New technologies can also help to ...

  • Case No : 601: Reducing NOx emissions from Nirtic Acid Manufacturing Plants with NOx Abatement or NSCR

    NOx Abatement is a Non-Selective Catalytic Reduction (NSCR) technology that has a long and proven track record for controlling NOx emissions from nitric acid manufacturing plants. It can be used to alter the NO to NO2 balance (decolourization) or to eliminate NOx through catalytic reaction with a fuel as a reductant. Nitric Acid Production The first part of the nitric acid process involves ...

  • A Non Regenerative DPF fitted to a Perkins 3012TAG2A Standby generating set - Case Study

  • Recent degassing jobs - case study

    PURGIT has recovered hundreds of tons of tank vapor. Our process takes tank vapor and recovers it by condensing the vapor to liquid that can be recycled or sold. PURGIT does not waste valuable natural resources. The PURGIT process condenses tank vapor meeting environmental regulations and the recovered condensate is available for recycling. This is the most interesting and sophisticated vapor ...

  • Greenhouse Gas Emissions Control

    Most of the time, people think about Greenhouse Gas (GHG) emissions with carbon dioxide, which is the most common of the GHGs. While fairly typical, carbon dioxide isn’t the only GHG U.S. Environmental Protection Agency (EPA) regulates. Since EPA has begun regulating GHG emissions under its Clean Air Act authority, sources of emissions from others may require add-on air pollution control ...

  • Case No. 501: New QXC Silencer/Converter Installed on Waukesha H24GSID 375 KW Natural Gas Engines Achieves 2007 California NOx Regs

    Generating power with natural gas engines in large commercial buildings, while controlling emissions and noise from the engines requires a unique catalytic solution. Johnson Matthey’s new QXC model 3-Way converter silencer was chosen for the task. This design contains a unique catalyst element sealing system that insures against pollutant bypass.   Background Equity Offices had a need to ...

  • Hurricane Cyclones: Dedusting and Emission Control - Case Study
