  • Oil Analysis-Proper Testing for Maximum Value and Equipment Condition Information
    In order to quickly and accurately determine the "cause and effect" of oil and wear related problems, proper tests and procedures based on the equipment sampled and its application must be performed. This paper details the appropriate test slates for various types of industrial equipment
  • New ASTM Method for Measuring Oil and Grease in Water and Soil
    . D 3921 used Freon as the extraction solvent. The new ASTM Method D 7066 ­ 04,. Standard Test Method for dimer/trimer of chlorotrifluoroethylene (S-316) Recoverable. Oil and Grease and Nonpolar Material by Infrared Determination, uses a similar. extraction procedure with a more ozone friendly
  • Zeta Potential Measurement (Aqueous and Non-Aqueous, Iso-Electric Point Determinations)
    for regulatory authorities. Samples can be presented as dry powders, or suspensions in aqueous, oil or organic solvent media. Image analysis can be used to measure particle size from 0.7 micrometers to 2 mm. By its very nature its dynamic range is more limited than with the other, ensemble, techniques
  • Incremental Ring-core Determination of the Principal Residual Stress in a Duplex Stainless Steel Centrifuge (.pdf)
    Large separator centrifuges are widely used in the production of corn oil, cornstarch, and starch derivatives found in many household products including bread, toothpaste, diapers, and filters. A photo of a large centrifuge is shown in Figure 1. Centrifuges are used to efficiently separate
  • American Airlines Refuses To Be Distracted from Long-Term Goals
    but also provided American with greater stability. And, during the oil price spike, as most other airlines deferred or canceled aircraft orders, American continued to accelerate its narrow-body replacement plan and even announced a huge order for Boeing's new 787 model. In these and many other areas
  • Using Portable IR Analyzer to Measure Soot Levels in Diesel Oils
    to absorbance which is proportional to concentration for quantitative determination. þÿ The soot is maintained in suspension by the dispersant additives of the lubri-. cant. As soot levels increase, the viscosity of the oil also increases. At high. levels, this suspended soot can become abrasive, and can
  • Particle Size Analysis for Drilling in Petroleum Industry (.pdf)
    In order to drill a successful oil well, most drilling operators will use a good drilling fluid or mud (figure 1). Mud cools and lubricates the drilling tool, helps to attack the rock by injection under pressure, and cleans out the hole, carrying away the pieces of crushed rock. These mud systems
  • are not. Salt water is a mixture of water and NaCl and is homogeneous if thoroughly mixed, with all the salt dissolved. Oil in water is a heterogeneous mixture. Both types of mixtures can be separated into their component parts by physical means. A salt water mixture can be separated by distilling
