  • NEO Monitors conquers the Quasi-impossible

    China is a world factory powered by its abundant coal resource. China is facing a huge environmental challenge brought together with the fossil-fired power plants. China has therefore been conducting technical retrofit to the engines of its economy, by introducing emission control facilities. Selective Catalytic Reduction (SCR) technology is one of the most widely applied emission control ...

  • Plant reduces utility expenses with new emission control system - Case Study

    The steadily increasing natural gas prices near the end of 2004 were becoming a substantial operating cost burden on a facility producing automolive painl and coatings and developing coating products. The major consumers of natural gas at this facility were the main system of boilers which supplied steam energy throughout ihe facility and two Regenerative Thermal Oxidizers (RTOs) which controlled ...

  • U.S. Air Force DOD Project - Case Study

    Environmental Issues Controlling the off-gas from a remediation project, where high concentrations of petroleum hydrocarbons are present, can be a difficult if not dangerous process when utilizing internal combustion engines and conventional oxidation technology. In more recent years, the use of high vacuum pumps to accomplish both liquid and gas phase extraction — ...

  • Studying the Effect of Global Warming on Tropical Crops

    Researchers have long been using impact studies to study the effects of climate change on cocoa growth. These studies mimic conditions predicted at the end of the century1 such as higher levels of drought and higher levels of atmospheric CO2. Studies have shown that increased levels of CO2 may help offset the negative effects of reduced water availability on the ...

  • Selecting the Right Air Quality Monitor

    There are many types of air quality monitors available, but which one is the best choice for measuring gaseous air pollutant concentrations? There are two classes of such air quality monitors: sampling monitors and in-situ monitors (“in-situ” = “in the original position”). Sampling monitors utilises a manifold through which the air to be analysed is pumped. A small air ...

  • Adsorption and catalytic oxidation of organic pollutants using Fe-zeolite

    In this work, a natural zeolite, modified and loaded with iron (NZ-A-Fe) as a heterogeneous catalyst, was characterized for its suitability as a permeable reactive barrier (PRB) material for treatment of aromatic hydrocarbons in groundwater. Adsorption and oxidation processes were analyzed. Batch adsorption tests for benzene, toluene and xylene (BTX) aqueous concentrated solutions were ...

  • Real-Time Weather Data

    When the University of Minnesota Solar Vehicle Project (UMNSVP) team was looking for a weather station to compete in the Bridgestone World Solar Challenge, they contacted Columbia Weather Systems. The Magellan MX Weather Station with meteorological parameters plus GPS and compass readings gave the team the data they needed to complete the grueling race across the Australian Outback with their ...

  • Nature Energy article: ‘Open discussion of negative emissions is urgently needed’

    At the moment, nearly all model-based scenarios that limit global warming to 2 °C or less use negative CO2 emission technologies (NETs), particularly bio-energy with carbon capture and storage (BECCS). Still, investments in these technologies continue to be relatively small, and concerns are being raised regarding the large-scale application of such technologies. If no explicit policy ...

  • Multi-point monitoring of nitrous oxide emissions in three full-scale conventional activated sludge tanks in Europe

    The large global warming potential of nitrous oxide (N2O) is currently of general concern for the water industry, especially in view of a new regulatory framework concerning the carbon footprint of water resource recovery facilities (WRRFs). N2O can be generated through different biological pathways and from different treatment steps of a WRRF. The use of generic emission factors (EF) ...
