  • High Flow Delivery Systems for Bulk Specialty Gases
    concentration in gas phase for hydrogen chloride and ammonia was measured by an FI1R spectrometer. The efficiency of Matheson Tri-gas' Nanochem series purifiers was tested at a wide range of flow rates. Heat was introduced to the Bulk Specialty Gas Unit (BSGU) and the distribution system during the purification
  • Flow Switches for Oil/Gas Refinery Water Treatment
    The water used in the the cooling units, desalter units, and other water from throughout the plant creates a large amount of wastewater with VOC's that must be treated before it is recycled or discharged. There are many different types and choices of systems, chemicals, filters, membranes, screens
  • Micro Fluidic Flow and Pressure
    The footprint of mass flow and pressure sensors can be substantially. reduced using MST/MEMS. Equipment manufacturers are looking for compact. solutions to monitor or control the gas flow or pressure. within their systems. As these systems are getting smaller. and smaller, the incorporated flow
  • Natural Gas in Venezuela
    Hoffer Flow Controls has recently supplied two computerized natural gas turbine flow measuring systems to Venezuela's gas industry. These systems accurately measure "mass" flow rate and total. Venezuela has enormous gas resources and measuring it accurately is critical because of its value. In one
  • Package Hermeticity and Gas Analysis
    leak rate range of interest. Most test methods cited use a pressurization cycle with a tracer gas or fluid, followed by a measurement of the amount of tracer entrapped in the package, or its rate of flow from the package (per unit time).
  • Eliminating Need For Gas Preheat in Pressure Regulation
    and is not. affected by the gas flow rate through the unit.
  • Flowmeters Benefit From Silicon Advances
    and provides an end-to-end width that is identical to an ASME BPE 180 elbow. Sensor Detects Low Gas, Liquid Flows Well-suited to pulsing or periodic flows, these in-line flow sensors provide rapid response and can monitor changes as low as 5 ml/min (0.001 GPM). Solid state device has no moving
  • 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
