  • Measurement of oxygen during the purification of glycerin – Case Study

    Background information Glycerin is a basic chemical which is used in creams and ointments, in antifreeze and brake fluid for vehicles, as a plasticizer, and as a base for paints and lacquers. Glycerin is produced as a by-product during the manufacture of soap. This was the main source of glycerin for many years. However, the production of biodiesel has increased greatly in the last ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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. ...

  • 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. ...

  • 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 ...

  • How viscosity affects flow rates

    Choose the Best Peristaltic Pump for the Job! A frequent question regarding peristaltic pumps is how viscosity affects flow rate. The short answer is; as viscosity increases, flow rates decrease. That being said, there are various factors which need to be understood when considering a peristaltic pump for any application that requires pumping viscous fluids. The physical ...

  • Application notes - viscosity measurement

    Most laboratory viscometers employ the well-known principle of rotational viscometers to measure viscosity by sensing the torque required to rotate a spindle at a constant speed while it is immersed in the sample fluid. This is because the torque, generally measured using the reaction torque on the motor, is proportional to the viscous drag on the immersed spindle and thus the viscosity of the ...
