  • Taxpayer dollars subsidizing destruction

    One way to correct market failures is tax shifting—raising taxes on activities that harm the environment so that their prices begin to reflect their true cost and offsetting this with a reduction in income taxes. A complimentary way to achieve this goal is subsidy shifting. Each year the world's taxpayers provide at least $700 billion in subsidies for environmentally destructive activities, such ...

  • Air Emissions/Off-Gas Treatment

    A number of technologies have been widely applied for removal of VOCs from off-gas streams. However, the application of these technologies to off-gases from site remediation may be quite limited. Biofiltration has been widely applied for VOC destruction in Europe and Japan, but it has only recently been used in the United States. Catalytic and thermal oxidation are widely used for the destruction ...

  • 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 ...

  • A warming world means more destructive storms

    Elevated global temperatures bring a number of threats, including rising seas and more crop-withering heat waves. Higher surface water temperatures in the tropical oceans also provide more energy to drive tropical storm systems, leading to more-destructive hurricanes and typhoons. The combination of rising seas, more powerful storms, and stronger storm surges can be devastating. Just how ...

  • Combating Corrosion - Committee G01 Standards Fight Nature’s Destructive Tendencies

    The evening news may leave many of us feeling war-weary, but one ASTM International technical committee has been successful in conflict of a different sort. It’s a commonplace but epic struggle between the natural and civilized worlds — the fight against metal corrosion. For the past half-century, the weapon of choice of ASTM Committee ...

  • Climate Change Driving Weather off the Charts

    Meteorologists are calling the typhoon that slammed into the Philippines with 195-mile-an-hour winds on November 8, 2013, the most powerful tropical storm to make landfall on record. Super Typhoon Haiyan had gusts reaching 235 miles per hour and a storm surge swelling as high as 20 feet, so the destruction it left behind matched that of a tornado combined with a tsunami. Three days later, at the ...

  • Modelling and exergoeconomic optimisation of a gas turbine with absorption chiller using evolutionary algorithm

    In this paper, thermodynamic modelling of a gas turbine cycle with absorption chiller is performed. A thermoeconomic approach is utilised to find the most optimal values of design parameters for practical applications. Some design parameters considered are compressor pressure ratio, compressor isentropic efficiency, gas turbine isentropic efficiency, gas turbine inlet temperature, HRSG pressure, ...

  • 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 ...

  • Composting generates cash for greenhouse gas benefits

    Chicago Climate Exchange (CCX) recently finalized an initiative to develop a protocol for issuing offsets to projects that avoid greenhouse gas (GHG) emissions through composting or other similar approaches. This article explores the development of the new protocol, reviews its key attributes and describes how an entity can earn tradable credits for its GHG mitigation project. In 1992, the U.S. ...

  • Thermal oxidizers for natural gas savings - Case Study

    It’s in the news every day; the natural gas production industry is experiencing record growth. The gas reserves in the United States are thought to hold enough natural gas for hundreds of years and the gas and oil industry has improved extraction techniques that make gas production more affordable and less impactful on the landscape. Good news for the country and our environment. The ...

  • Gas cell selection for analysis of electronic gases

    APIMS and FTIR remain the preferred analytical tools for monitoring impurities in the electronic  specialty gases used by the semiconductor industry, although other tools such as CRDS are currently finding application in selected cases. FTIR spectroscopy offers the advantage of the simultaneous measurement of all gaseous species that exhibit dipole moment changes during vibrations at ...

  • Why high temperature combustion of landfill gas?

    Due to the accumulation of knowledge and the tightening of environmental law, the landfill technology has increasingly become concerned with the management of trace compounds in landfill gas. With landfill gas, contamination is through sulphur, chlorine, fluorine, halogenated hydrocarbons and heavy metals. Other trace elements such as volatile organic compounds (VOC), impose environmental ...

  • Columbus, Georgia`s High-Efficiency, Low Cost, Digester-Gas-Fired Power Plant

    ABSTRACTGrowing concern over the cost of power and long-term availability of limited fossil fuel resources for the production of electricity have caused electrical utilities and governments to promote “green” or renewable power. Solar, wind, geothermal, biomass, biogas, and low-impact hydroelectricity are current acceptable green-power sources. Digester gas is a renewable, green energy resource ...
