  • Intellisenc Greenhouse Controllers for control of CO2, Humidity and temperature

    Optimum and accurate CO2 level is important for effective and efficient plant growing. Too much CO2 creates diminishing return on expense and too little fails to utilize your capital investment. Optimum control of all facets of the growing environment results in high productivity at less costs. Plants need to be able to shed moisture to maintain their capacity to draw in nutrients from the soil. ...


  • Determining Proper Cooling Tower Size

    To maximize water-based cooling tower benefits, the appropriate tower size must be selected, requiring the identification of several critical factors. Cooling towers are a relatively inexpensive and reliable way of expelling heat from a number of industrial processes, including nuclear & thermal power plants, petroleum refineries, petrochemical plants, food processing plants, as well as HVAC ...

  • 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 ...

  • Effective Temperature Control for Cement Kiln Off-Gases

    INTRODUCTIONEffective off-gas temperature control without unwanted side effects can be achieved in many cement plants with state-of-the-art evaporative spray technology. Gas temperatures have elevated in recent years from as low as 180°C to over 370°C. This is coincident with a higher proportion of 'dry' operation kilns. Evaporative cooling water sprays in conditioning towers, ducts or at the ...


  • Stability and accuracy of CIRAS-2 Water Vapor (reference humidity): control option 1

    Summary Rapid large-scale fluctuations of carbon dioxide and water vapor, although unnatural and artificial in the plant world, are desirable attributes for gas exchange systems from a sampling efficiency standpoint. As PP Systems’ benchmark IRGA system for gas exchange and photosynthesis research, CIRAS-2 was designed for and expected to have exceptional response times to ...

  • Exergetic destructions in steam generation system: Azzour plant

    The aim of this research is to investigate the exergetic destructions of Azzour steam generation system. The exergy destructions (irreversibilities) of the steam generation system were analysed based on actual plant operating data. Three irreversible processes were investigated; combustion, heat transfer and streams mixing processes. Sensitivity analysis was carried out to study the effects of ...

  • PureAire Makes Oxygen Monitor for Nitrogen Generators

    Nitrogen generators are most commonly used in areas where on-demand nitrogen is preferred rather than, storing liquid nitrogen (LN2) in cylinders.  Nitrogen generators have a lower cost of operation, and can be used where smaller amounts of nitrogen are needed. Nitrogen generators are used in the pharmaceutical industry, testing laboratories, cryogenic facilities, welding manufactures, and ...

  • Monitoring radon and its progeny in the environment of the vertical 15 UD Pelletron accelerator facility

    Environmental radioactivity due to radon and its progenies in the ambient air at the vertical 15 UD Pelletron accelerator facility of the Inter University Accelerator Centre, New Delhi, India was evaluated to calculate the annual effective dose to the workers and users. The radon activity was measured with an active monitor. The activity concentrations of the radon progenies were measured ...

  • Case Study: Singapore Airlines

    Ellis was contacted after a client had several complaints from employees related to air quality. Ellis conducted exposure monitoring for CO2 and CO, and also took measurements of temperature and relative humidity. Results of the study showed CO2 and CO to be well under the PEL (Permissible Exposure Level) for those two gases. However, elevated temperatures occurring later in the day appears to ...
