  • In-House Oil Analysis Lab Saves Gold Mine Millions in Downtime, Repair and Replacement Costs

    A low-grade surface mining operation depends upon huge and expensive equipment such as Hitachi 5500 shovels and Caterpillar 793 haul trucks. Oil analysis is essential to identify problems so they can be corrected before they cause equipment to go down for major repairs. In the past, a multinational mining firm sent samples to an outside lab for analysis but the cost of this approach limited the ...

  • Techniques for Soot in Oil Analysis

    Since no engine is 100% efficient, products other than carbon dioxide and water will be formed during combustion. One such product produced from incomplete combustion is soot. Soot is a mass of mainly carbon particles that are typically spherical in shape. As soot levels rise, the soot particles begin to clump together and ...

  • Guide for Measuring Fuel Dilution in Lubricating Oil

    Fuel dilution in oil can cause serious engine damage. High levels of fuel (>2%) in a lubricant can result in decreased viscosity, oil degradation, loss of dispersancy, and loss of oxidation stability. Fuel dilution is one of the most important lubricant failure modes in internal combustion engines. It usually occurs due to ...

  • Measuring Oil Chemistry: Nitration, Oxidation, and Sulfation

    An in-service lubricant encounters air, heat, pressure, corrosive agents, and other factors that cause chemical changes in the oil. A change in oil chemistry can affect the ability of the lubricant to do its job (for example if crucial additives have been depleted). Over time, these chemical reactions can result in build-up of ...

  • E-Guide Measuring Oil Viscosity

    The most important physical property of a lubricating oil is viscosity. Viscosity determines the load carrying ability of the oil as well as how easily it circulates. The correct balance between high viscosity for load carrying and low viscosity for ease of circulation must be considered for any lubricant and its application. ...

  • Viscous Pumping in Focus

    The performance of a pump is influenced when it handles viscous fluids such as crude oil. For the configuration and design of pumps, this is key. In the industry, pump performance curves are developed by testing with water at temperatures around 25°C and corrected to a specific gravity of one. Engineers use this standard so that they have comparable measurement values around the ...

  • 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 allow the oil ...

  • Vacuum systems for tall-oil applications

    Tall oil is a viscous oily liquid and considered one of the most important by-products of wood pulp manufacturing. Through a fractioning process crude tall oil can be turned into valuable fatty and resin acids. Vacuums play a key role in this procedure. An application in Finland currently proves that technology from Hanover-based Körting is ideally suited for this purpose. ...

  • Correlation and prediction of saline solution properties for their use in mineral processing using artificial neural networks

    Artificial neural networks (ANNs) are applied to correlate and predict physico-chemical, transport and thermodynamic properties of seawater. Values of these properties are needed in the design, simulation and optimization of processes in which seawater is used, mainly in the mining industry. Density, vapor pressure, boiling temperature elevation, specific heat, viscosity, thermal conductivity, ...

  • Artificial neural network modeling of scale-dependent dynamic capillary pressure effects in two-phase flow in porous media

    A computationally efficient and simple alternative platform for the prediction of the domain scale dependence of the dynamic capillary pressure effects, defined in terms of a coefficient named as dynamic coefficient (τ), is developed using an artificial neural network (ANN). The input parameters consist of the phase saturation, media permeability, capillary entry pressure, viscosity ...

  • Development of low-cost rotational rheometer

    Liquids with non-Newtonian properties are presented in many engineering areas, as for example in membrane bioreactors where active sludge exhibits shear thinning properties. Therefore, the ability to determine the rheology's dependence on shear is important when optimising systems with such liquids. However, rheometers capable of determining the viscosity are often expensive and so a ...
