  • Who Needs Continuous Emissions Monitoring?

    Continuous emissions monitoring (CEM) is about monitoring air pollutants generated by a specific activity and emitted to the ambient air, typically through a tall stack or other exhaust pipe. The “activity” can be some industrial process like a power plant or a waste incinerator, but it can also be on a much smaller scale such as a car equipped with an internal-combustion engine. ...

  • Air Pollution Control in the Printing and Web Coating Industries

    For many U.S. companies in the printing and web coating business, the use of an Air Pollution Control System (APCS) to control harmful air pollutants is not new.  In these industries, depending upon their location, companies have been installing APCS since the early 1970's.  However, for some companies the clock is still ticking regarding their compliance with local, state and federal ...

  • Like a phoenix from the ashes

    Thanks to growing environmental awareness, waste is increasingly being separated and recycled. However, residual waste always remains that can't easily be recycled. This ends up in waste incineration plants (referred to as KVAs in Swiss German) for disposal and reclaiming, such as the KVA Linthgebiet in Niederurnen in the Swiss canton of Glarus. Due to the strict environmental specifications ...

  • Case study - Reactor vent emission control

    OVERVIEW Many chemical and petroleum companies use batch reactors to make their products.  These reactors typically have vents which are opened and closed during emptying, filling, mixing, heating or cooling and other steps of the production process.  The gases coming from these vents must be controlled under most government regulations.  Generally speaking, the ...

  • Case study - Destruction of inert process emissions

    Many chemical companies use batch reactors to make their products.  These reactors typically have vents which are opened and closed during emptying, filling, mixing, heating or cooling and other steps of the production process.  The gases coming from these vents must be controlled under most government regulations.  Generally speaking, the emissions produced are inert (little or no ...

  • An analysis of extinction coefficients of particles and water moisture in the stack after flue gas desulfurization at a coal-fired power plant

    Two important factors that affect in-stack opacity—light extinction by emitted particles and that by water moisture after a flue gas desulfurization (FGD) unit—are investigated. The mass light extinction coefficients for particles and water moisture, kp and kw, respectively, were determined using the Lambert-Beer law of opacity with a nonlinear least-squares regression method. The ...
