  • Ferrography Made Easy With The FerroCheck 2000

    The measurement and trending of abnormal ferrous wear debris in machinery lubrication oils is arguably the most significant indicator of machinery health and a key predictor of catastrophic machinery failure. There are several methods available to measure the ferrous content of lubrication oil. ...

  • GC Analysis of Crude Oil Samples in Compliance with ASTM D5307

    In the ASTM D5307 test method, crude oil containing components with boiling points to temperatures in excess of 538C (C44 or equivalent) are analyzed by a simulated distillation GC system by the internal standard method. A detailed boiling point distribution graph is created for the fraction with boiling points lower than 538C. The fraction with boiling points above 538C is calculated as ...

  • Measurement of naphthenic acids in the receiving waters around an offshore oil platform by passive sampling

    Polar organic chemical integrative samplers (POCIS) were deployed in the vicinity of an offshore oil installation and analysed for naphthenic acids (NA). POCIS accumulated a range of mono to tetracyclic NA, with different degrees of alkylation, with monocyclic acids being the most abundant. POCIS or similar polar samplers may currently be the only way to measure exposure to NA from offshore ...

  • Characterisation of water–oil drainage process through a reservoir rock sample by digital core analysis

    Oil–water relative permeability and capillary pressure of a water–wet digital core are computed using the finite–volume/volume of fluid method and mimicking traditional laboratory steady–state experiments carried out on a water saturated sample. Commercial software is used for immiscible multiphase fluid flow simulations, carried out on a low–cost multicore workstation, and the pore–scale data ...

  • New ASTM Test Method Offers Quick and Easy Oil and Grease Measurement for Water and Soil Samples

    Onsite Field Measurement of Oil and Grease A quick and easy field analysis method for determining oil and grease concentration levels is important for both offshore oil platforms and soil remediation sites.. Prior to the Montreal Protocol, infrared (IR) analysis using Freon as an extraction solvent was a widely used field and laboratory method. In 1999, the U.S. EPA promulgated Method 1664A ...

  • Flaxseed Oil Waste

    A commercial manufacturer of flaxseed oil was having a problem obtaining the FOG and TSS level required by their local POTW. A sample was submitted to our laboratories for treatment analysis. The wastewater was at a pH of 7.0 so no adjustment was required. The sample was treated with Floccin J and the results met their ...

  • Oil in Power Plant Wastewater

    The water is from the operations of a steam power plant located in the Bahamas. The water samples were taken from the Unit 31 (lower oil content) and Tank #3 (a higher oil content). The samples were tested and it was found through the jartesting procedures that the Floccin K was the best choice for floc size and water clarity. The Unit 31 was dosed at 0.5 gram in 1,000 ml and the Tank # 3 water ...

  • Oil & Grease applications notes

    EPA Method 1664A & 1664Bwas developed to determine the precise amount of n-Hexane Extractable Material (HEM) and Silica Gel Treated n-Hexane Extractable Material (SGT-HEM) that exist within a water sample. The HEM or SGT-HEM that is extracted contains a mix of various hydrocarbons usually residing within the semi-volatile range with a boiling point greater ...

  • The analysis of polycyclic aromatic hydrocarbons in marine samples

    Polycyclic aromatic hydrocarbons (PAH) have been determined in marine samples for many years, but have only rarely been included in either national or international monitoring programmes. PAH can arise in the environment from natural sources, oil and petroleum products and combustion processes. Although oil spills influence PAH concentrations in local areas, the major sources of PAH are ...

  • Bioremediation of an Oil Spill

    Bioremediation is the method of choice to effectively clean up a small spill of hydrocarbons. In this case, five-hundred liters of BTEX has spilled from an above ground storage tank into a pasture that is located at the west edge of the Royal Roads University (RRU) grounds. The soil is classified as a Gleyed Eutric Brunisol based on recent laboratory analysis; it contains clay, but is fairly ...
