  • Put energy into emission control projects

    Many companies feel pressured to spend the least amount possible to meet environmental regulations, primarily because compliance isn’t a profit generating endeavor. What some environmental and compliance managers fail to realize is that emission control equipment can quickly become a profit decreasing endeavor with this penny wise-pound foolish approach. With mandatory greenhouse gas (GHG) ...

  • EPA Increases Ammonia Emissions Control

    Concern about ammonia emissions in the air and the water continues to grow, both officially and unofficially. As U.S. Environmental Protection Agency (EPA) moves to further reduce ammonia concentrations in surface waters, common water treatment methods transform what had been a water pollution problem into an air pollution issue. Earlier this year, EPA released its draft Integrated Risk ...

  • Carbon Fiber Emission Control Strategies

    Problem Carbon fiber (fibre) and graphite reinforced polymers are materials that have, and will continue to revolutionize the products we use everyday by making them stronger, lighter and more durable.

  • Continuous emission monitoring and control of packed tower odor control systems using the sycamore CEM

    ABSTRACT Packed-tower chemical scrubbers, with sodium hydroxide (caustic) and sodium hypochlorite (bleach), are commonly used to treat foul air from wastewater treatment processes. The available control mechanisms include a pH probe and controller for the sodium hydroxide feed, an oxidation reduction potential (ORP) probe with a controller toestablish the bleach feed, and proprietary ...

  • 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 ...
