  • Holcim Ste. Genevieve Cement Plant - Case Study

    Big and beautiful The new cement manufacturing facility of Holcim (US) at Ste. Genevieve with a production capacity of four million tonnes per year went on stream mid-2009 and is one of the most environmentally-efficient cement plants in the Holcim Group. It is 40 percent more energy-efficient than the Holcim (US) plants that were closed in 2009 and emits 10 to 25 percent less ...

  • Primary Standard Gas Flow Calibration—The Only Guarantee of Accuracy

    At Sierra, we have a saying: “An instrument’s accuracy is only as good as its calibration.” The accuracy of your mass flow controller (MFC) is essential in assuring the efficiency, performance, and quality of your flow meter. In many cases, if your instrumentation is not calibrated, then a decline in performance is possible due to ...

  • The Challenge AER-200 Respirqmeter System for anaerobic applications

    The CHALLENGE AER-200 Respirometer System consists of one or more biological reaction vessels, gas flow measuring cells, and a computer. The gas measuring base contains eight flow cells and associated interconnecting circuitry. As gas flows through each cell under the influence of a slight pressure caused by gas production in the reaction vessel, bubbles of a fixed volume are formed in the lower ...

  • Influence of spray dryer parameters on exergetic performance of microencapsulation processs

    Exergy analysis of fish oil microencapsulation process by spray drying was carried out. The process was performed on a mini–spray dryer and skim milk powder was used as the coating wall material. The drying experiments were conducted to find the effects of inlet drying air temperature, drying air mass flow rate, feed mass flow rate, and spraying gas mass flow rate on inlet exergy, outlet exergy, ...

  • Characteristics of three-phase internal loop airlift bioreactors with complete gas recirculation for non-Newtonian fluids

    Hydrodynamic and gas–liquid mass transfer characteristics, such as liquid velocity, gas holdup, solid holdup and gas–liquid volumetric mass transfer coefficient, in the riser and downcomer of the gas–liquid-solid three-phase internal loop airlift bioreactors with complete gas recirculation for non-Newtonian fluids, were investigated. A mathematical model for the description of flow behavior and ...
