  • Measurement of Freon 14 (CF4) in an Aluminium Production Plant
    Production of aluminium using traditional technology can result in the release of the "greenhouse gas " Freon 14 (CF4). In order to reduce the release of Freon 14 to the atmosphere, improvements must be made to the production process. To see the effectiveness of these improvements, Freon 14 must
  • Checking Cleaning Efficiency of Metal Parts
    For applications involving gas regulators, space shuttle components, weaponry parts or oxygen sensors, it is critical that metal parts must be free of hydrocarbon contamination before use. Prior to its ban due to ozone layer depletion, Freon was the most commonly-used solvent for metal parts
  • New ASTM Method for Measuring Oil and Grease in Water and Soil
    A quick and easy field analysis method for determining oil and grease concentration levels is important for offshore oil platforms, soil remediation sites and industrial wastewater measurement of Fats, Oils and Grease (FOG). Prior to the Montreal Protocol, infrared (IR) analysis using Freon
  • Ammonia Pressure Measurement using Thermal Flash Protection (.pdf)
    Situation: Ammonia offers refrigeration pump and compressor manufacturers an improved efficiency over Freon based systems. However, the thermodynamic behavior of ammonia is very different from Freon. When the refrigeration pump turns on, the ammonia temperature rapidly changes from 100°F to -70°F
  • Produced Water Monitoring (.pdf)
    Due to the non-availability of Freon, there is need for an alternative method to measure the concentration of hydrocarbons in the effluent today. Current methods use solvent extraction and IR analysis of water samples. In this paper we present an alternative method, which does not use any solvents
  • MICRO: Products In Action
    properties of PFPE coolants do not break down, thus eliminating the need for expensive resistivity monitors and filtration systems that often have been required for other coolants, such as ethylene glycol, glycol/ deionized-water mixtures, and Freon. PFPE fluids are known for being clean and inert and having
  • The Hidden Costs of Compressed Air/Gas Leaks
    , Carbon Dioxide, and Freon systems can be. The focus of this article will be not only how leaks can negatively impact the system as a whole, but also how leaks can affect the environment and quite possibly the well being of the personnel that have to work around them.
  • Air Dryer Adds Hundreds of Dollars of Production/Week on High-Precision Slitting Machines
    the machines to rust and stick. At least three times a week one of the slitting machines was down for an hour while the valves were cleaned or replaced. The new air dryer uses advanced membrane separation technology instead of refrigerants or freon to remove 99.9 percent of the moisture from
