  • Flow Stabilisation in Simulated Moving Bed Chromatography Using Flow Meters and Feedback Control
    , flow perturbations (e.g. from gas bubbles) have to be accounted for when designing process robustness. For investigating the applicability of feedback flow control, a Knauer C9116 lab scale SMB unit was equipped with Mini CORI-FLOW M13 coriolis flow controllers.
  • Air Emissions from the Automobile Manufacturing Industry: A Bio-Oxidation Pilot Study of Paint Emissions Control
    were made to airflow (adjusting residence time) and sump water recirculation spray (biotrickling filter flow rate and biomatrix chamber timing) while monitoring the VOC inlet and outlet concentrations using a gas chromatograph equipped with a flame ionization detector (FID - Method 25A).
  • White Paper - Thermal Processing Optimization: Using Advanced Rotary Tube Internals to Achieve Operational Improvements
    The use of tube internals in a rotary furnace can increase heat transfer surface area, improve radial mixing, improve gas-solid interactions, control gas flow direction, and even control material dwell time or velocity through the tube. All of these can result in a reduction of residence time
  • Medical Device Link .
    , improvements in gas pressure and flow control enable more-detailed control of process variables. The stand-alone gas unit is wired into the injection molding machine. It uses process signals to time and control the gas-assist process sequence. The gas unit is also linked to a
  • MICRO: Critical Materials
    device geometries is the delivery of gases to the process tools. Controlling gas delivery, in turn, requires accurate flow control devices such as mass-flow controllers (MFCs). Typically, gas delivery is accomplished by means of an MFC located on a process tool among other gas-delivery components. Most
  • Proportional valves eliminate design headaches
    of closed-loop control systems. Proportional valves are a great alternative when an application requires more than on-off control, but not the high precision and expense of servovalves. As such, proportional valves are widely used in a multitude of applications, including the control of gas and air flow
  • Crossflow Scrubber and Air Filtration Pilot System
    This design utilizes stage-wise scrubbing and filtering of gases and contaminants in a compact, easy to maintain package. Inherent in the design is the flexibility to collect a diverse range of contaminants and at a high gas flow turndown (allowing for large swings in the gas volume). Kimre TM
  • MICRO: 2004 Greatest Hits
    water generators. Designed to supply DIO water to single-wafer cleaning tools, the compact and self-contained unit provides ultrapure DIO with a high and accurate ozone concentration at a constant delivery pressure. The unit delivers DIO water with ozone concentrations between 5 and 55 ppm at flow
