  • Combustible Dust: It Doesn’t Take Much

    A dust accumulation of 1/32 of an inch deep—about the thickness of a dime—covering just five percent of a room’s surface area doesn’t sound like much, but it’s enough to cause a catastrophic explosion, according to the National Fire Protection Association (NFPA). Although good engineering and safety practices to prevent dust explosions have existed for decades, there ...

  • Case study - Biogas desulfurization and siloxanes abatement

    MCFC project by CETAGUA (Mataró – Spain) Reducing the carbon footprint of our society is imperative. This can be achieved by capturing and confining anthropogenic CO2 emissions as well as by replacing fossil-based fuels with renewable or waste-derived fuels. MCFCs (Molten Carbonate Fuel Cells) are unique in being able to do both these things. Thanks to their operating ...

  • Simultaneous regeneration of exhausted zeolite and nitrogen recovery using an air stripping method at alkaline pH

    Ammonium nitrogen recovery using natural zeolite from the permeates of anaerobic membrane bioreactors was investigated with batch and continuous experiments. Regeneration of exhausted zeolite was compared between mechanical shaking and air stripping, and experimental results showed the superiority of air stripping over the shaking. Liquid circulation and air flow rates were optimized in a ...

  • Controlling Pharmaceutical Coating & Drying Process Emissions

    Capturing and destroying harmful emissions from pharmaceutical processes can be challenging. It’s not because the volatile organic compounds (VOCs) are difficult to destroy using catalytic or thermal techniques. It’s because their concentrations can be so high. These process streams raise safety concerns, both when they’re collected in vents and when they reach the final ...

  • ‘Everyone is exhausted and frustrated’: exploring psychosocial impacts of the lack of access to safe water and adequate sanitation in Usoma, Kenya

    The lack of access to safe water and adequate sanitation pose significant health challenges for many individuals and communities in low and middle-income countries. Aside from direct health issues, the lack of access to safe water and adequate sanitation is increasingly associated with psychosocial concerns that affect the wellbeing of individuals and communities. However, the nature of these ...

  • Case study - Amine tail gas treatment

    COVERING YOUR TAIL GAS The discovery of new shale formations throughout the world and the development of new drilling technologies have increased natural gas production and prompted government agencies to instigate tighter air-pollutioncontrol regulations on processing operations. Unfortunately, meeting environmental regulations is not a profit-generating endeavor. Simply put, the time ...

  • Case study - Better maintenance starts with better documentation

    OXIDIZER SERVICE SERIES: PART 1 Your oxidizer system is both a significant investment in - and a long term commitment to - environmental compliance. Part of properly servicing your oxidizer system is maintaining the design documentation associated with that system. In the oxidizer design world, National Fire Protection Association (NFPA) standards are often viewed as good practice. However, not ...

  • Case study - Kiln emission control technologies

    Overview A specialty ceramic material manufacturer in the United States operates several custom-built furnaces in their manufacturing process.  Sometimes referred to as kilns, these high-temperature process devices are generally a major source of air pollutants and require an abatement technology to meet environmental regulations with the state or federal agencies.  As is the ...

  • Adsorption of hexavalent chromium by crosslinked chitosan–iron(III) in an air-lift reactor

    Column experiments were conducted in an airlift reactor containing a certain amount of crosslinked chitosan–iron(III) (Ch-Fe), to examine the effects of adsorbent mass, flow rate, and influent concentrations on Cr(VI) removal. The breakthrough time increased with an increase in Ch-Fe mass, but decreased with an increase in initial Cr(VI) concentration. The exhaustion time decreased with an ...

  • Tenax extraction as a simple approach to improve environmental risk assessments

    It is well documented that using exhaustive chemical extractions is not an effective means of assessing exposure of hydrophobic organic compounds in sediments and that bioavailability‐based techniques are an improvement over traditional methods. One technique that has shown special promise as a method for assessing the bioavailability of hydrophobic organic compounds in sediment is the use of ...

  • Optimizing the Slaking Process

    Poorly-slaked lime can have a major negative impact on lime consumption and the operating cost at an end-user’s site. The amount of lime used in the process is determined by a combination of slaking parameters. The optimisation of the slaking process will help drive operating costs down and also reduce CO2 emissions.  When the slaking of lime (ie, the conversion to calcium hydroxide ...
