  • Cloud Point of Diesel Fuel #3074

    The Cloud Point of a diesel fuel is the temperature below which wax forms giving the fuel a cloudy appearance. This parameter is an important property of the fuel since the presence of solidified waxes can clog filters and negatively impact engine performance. The traditional laboratory methods for the measurement of Cloud Point are optical in nature, but rely on cooling the fuel for the wax formation to occur. Guided Wave’s process analyzers can measure compositional changes in the fuel that will be directly related to the wax formation and hence the Cloud Point. This note will discuss the use of Guided Wave hardware and software tools for the measurement of the Cloud Point of diesel fuel using fiber optic-based, near-infrared (NIR) spectroscopy. NIR can be applied in real time directly in process.

    Measurement solution for CFC analyser

    CFCs are used in the manufacture of insecticides and herbicides and the environmental impact of their use must be well controlled. The treatment of CFC emissions to reduce the emissions in the intermediary steps of production needs to be monitored with 100% efficiency. Protea’s portable CFC analysers and continuous CFC monitoring systems can be configured with various sample inlets and analytical modelling to enable multi-samples to be measured on the one system. This means that both inlet and outlet to abatement systems can be monitored using the one analyser.

  • Analysis of aqueous solutions

    IR-Spectroscopy is not limited to gases, solid materials and pure liquids but also facilitates the measurement of solutes in aqueous media. Though, due to the strong and temperature dependent absorption of water, the usage of conventional IR-transmission and ATR accessories is not very suitable for the analysis in water. The CONFOCHECK is a dedicated FT-IR system for the fast, easy and sensitive analysis of aqueous samples. Using this system, preparing, measuring and evaluating any aqueous sample takes typically about 1 minute.

  • Variable frequency drive controls AC motors

    Consider integrating a variable frequency drive. It often can optimize energy efficiency by enabling you to match motor speed to the demands of the system. Look for opportunities, for example, to replace throttle valves or dampers used to restrict flow. However, a variable frequency drive may not make sense if the load on the motor is relatively small and constant — because speed changes will occur infrequently and any benefits from varying the speed will be negligible. So, thoroughly assess the system load profile to determine the scale and frequency of required speed changes before deciding about installing a variable frequency drive.

    Gas analysis & monitoring system for gas purity

    The purity of a gas is an indication of the amount of other gases contained in it. A high purity refers to a low amount of other gases. High purity gas are considered to be of better quality and are generally more expensive. The purity of the gas can be expressed as a percentage or as a decimal fraction. Applications for checking the purity of the gases across different industrial sectors by air separation plants, cryogenic facilities, the quality control of industrial gases to the steel mills, etc.

    Measurement solution for on-line carbon bed system

    Commonly, activated carbon beds are used as abatement systems on plant, with emissions being reduced by adsorption onto the bed. The efficiency of any abatement system is critical to its operation, not just in ensuring emissions are reduced as much as possible, but an efficient bed has cost savings for the operator.
