  • Wind Energy Production Estimates: Moving Beyond Time Averages

    No need to be a statistician to see that averages are often useful to compare different things. And yet, they often fall short as a true measure of performance. For instance, we use averages to compare the current weather against the climate normals or to get a sense of how our favorite sport team or player is doing. Team (player) statistics are a concise way of combining the scores from many ...

  • Two Detector Solution to Analyzing Sulfur

    Sulfur compounds are reactive, corrosive to pipes, and destructive to catalysts in petroleum refineries. Sulfur emission are strictly regulated globally. When released into the atmosphere sulfur dioxide converts to sulfuric acid resulting in adverse effects on human health and the environment. Sulfur detection is found useful in many other industries; therefore, detection of sulfur compounds in ...

  • The Boiler Optimization Journey

    The Boiler Optimization Journey talks about the evolution of power plant optimization software over the past 15 years, from neural network-based systems that advised operators how to bias fuel and air in the furnace to reduce NOx emissions, to integrated closed-loop combustion and sootblowing systems that use hybrid AI technologies, solve a broad range of challenges, and provide enhanced ...

  • Optimization of a Sulfur Recovery Unit

    Prior to Suncor’s purchase of the Spirit River facility, little attention was given to the LO-CAT unit. In general, over injecting chemicals into a LO-CAT unit will not result in operating problems, just higher than required operating costs. Consequently, in remote gas plants such as Spirit River, it is sometimes difficult to convince operators to change operating conditions if the unit is not ...

  • Optimal GPR antenna selection

    It is common knowledge to anyone practicing Ground Penetrating Radar (GPR) technology that lower center frequency antennas mean higher penetration and lower resolution. In the same way it is correct to say that higher center frequency antennas mean lower penetration and higher resolution. This is without any doubt an axiom that provides us with a rule of thumb on what to use and what not to use ...

  • Every kilowatt utilised optimally

    Heat recovery with AERZEN blowers As a part of an extensive renovation project, the city of Filderstadt modernised the Bombach wastewater treatment plant, located in the district of Bonlanden. Now, Delta Hybrid rotary lobe compressors made by AERZEN provide optimal oxygen supply, and, thanks to heat recovery measures, the energy balance has improved further. Although ...

  • Signs of optimism for a smarter future

    There are grounds for growing optimism around the opportunities for smart, data-driven technologies in the water sector, given the views of Amir Cahn, Director of Research and Business Development with SWAN, the Smart Water Networks Forum. He puts the proportion of water utilities who are moving forward with such technologies at only 5-10%, but he points also to the growing number of strong case ...

  • New Optimism for a Cleantech Future

    If you’ve not been paying much attention to cleantech in the last little while, it’s time to sit up and take notice — because post-Solyndra, cleantech has been quietly gaining momentum. We had the chance to take a close look at the fundamentals of cleantech over the last two months in co-authoring a new (and free!) 38-page research report in conjunction with Oakland, ...

  • Power use methods for optimal design of WDS: history and their use as post-optimization warm starts

    This paper describes an extension to the optimal power use surface (OPUS) methodology, which consists of applying a metaheuristic post-optimization process after a network has been designed through the OPUS algorithm. Four different types of metaheuristics were tested in this study. The OPUS methodology focuses on the setting up of efficient ways in which energy is dissipated and flow is ...
