  • Detection of abnormal wear particles in hydraulic fluids via electromagnetic sensor and particle imaging technologies

    Abstract Particle imaging, electromagnetic, ferrographic, and spectroscopic methods were used to evaluate hydraulic oil samples collected from machines known to be generating abnormal wear particles. Analytical ferrography confirmed the presence of large reworked ferrous particles and small rubbing wear particles in the oil samples. ICP emission spectroscopy was limited in its ...

  • Eliminate Degassing When Measuring Viscosity of Compressor Oils

    Compressor oils can create unique challenges when trying to measure viscosity. Dissolved gases from refrigerants, in particular, tend to bubble out when these oils are measured using traditional viscometers. This can create errors in the measurement, typically causing readings to be much lower than they should be. One way to get around this problem is to ...

  • 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 ...

  • Experimental investigation of effects of oil shale composition on its calorific value and oil yield

    This paper reports results of a detailed geochemical analysis carried out on representative oil shale samples obtained from the Attarat Um Ghudrandeposit, in Jordan. The conducted tests aimed to determine main features of the studied samples, such as oil yield, calorific value, organic and inorganic composition and moisture content. Based on obtained results of a large number of oil shale ...

  • Sulphur removal from used automotive lubricating oil by ionising radiation

    In this work, gamma radiation was used to remove sulphur from used automotive lubricating oil. The sample was fractioned and irradiated with 10, 20, 50, 100, 200 and 500 kGy doses in a 60Co irradiator (Gammacell-220 – 12 kCi). Fifty percent and 70% (v/v) of MilliQ water and 30% (v/v) of hydrogen peroxide were used to improve the radiolysis. The sulphur content, before and after the irradiation, ...

  • Case study - Oklahoma crude oil forensic analysis

    An oil company used Sitelab’s laboratory to perform oil forensic analysis testing crude oils from different well sites to determine the percentage of oil content from two formations. The wells tap into these zones at different depths, thousands of feet below the ground. Knowing what type of oil being pumped is important. All six oil samples had similar GRO content, but the PAH content in ...

  • Organochlorine pesticide and PCB residues in pharmaceutical, industrial and food grade fish oils

    Oils rendered from whole fish and from fish offal are an important primary dietary item in many areas of the world. In addition, fish oils are used extensively in the food industry as raw materials and ingredients. An extensive specialist market also exists for fish oils in dietary supplements. Traditionally, benefits have been conferred by their high vitamin D content in the prevention and cure ...

  • Establishing wear particle limits using the theory of Dynamic Equilibrium Condition (DEC) to predict when abnormal wear modes are taking place in machinery

    The basis of modern oil analysis programs is the use of optical emission spectroscopy (OES) to measure the ppm (parts per million) levels of wear metals, contaminants, and additives in oil samples. Whatever an oil lab may need to measure, multi-elemental analysis is the core of an in-service oil analysis program. This paper gives an overview of Rotating Disc Electrode Optical Emission ...

  • Petroleum biomarkers as tracers of Exxon Valdez oil

    Over the past quarter century, petroleum biomarkers persisted in sequestered Exxon Valdez oil in Prince William Sound and the Gulf of Alaska, hence the oil remained identifiable. These biomarkers are molecular fossils derived from biochemicals in previously living organisms. Novel pattern matching indicated the presence of Alaska North Slope crude oil (ANSCO) over the entire observation period ...
