  • Increasing Efficiency During Dewatering

    Identifying the optimal solids content of wastewater sludge, slurries and cakes can provide significant cost savings on chemical additives, haulage and incineration. It also helps optimize process control and ensure a consistent final product.

    There are several methods to test for solids content during the dewatering process. This paper will briefly explain the differences between the various methods and will be followed by an experiment to test the most common form of solids analysis - the oven method - against the advanced technology of the Computrac® MAX® 4000XL Rapid Loss-on-Drying Moisture and Solids Analyzer. The MAX® 4000XL will prove to be just as accurate as the standard reference method while being significantly faster and less dependent on operator technique.

  • Optical System Sets New Standards in Oxygen Measurements

    Optical Dissolved Oxygen Measurement in Power and Boiler Applications

    Over the past decade a few trends have started to gain pace within the industry, driving a change in instrumentation requirements for operations managers and plant chemists:

    • Maintenance and operations budget cuts have resulted in fewer plant personnel, forcing plant staff to optimize their workload even further
    • As the cost of building new power and boiler systems increase, many operators now look to plant life extensions as a solution to bridge gaps in production capacity at a lower investment premium

    These trends have changed the requirements in these applications. Starting from these trends, this article analyzes the options for oxygen measurements that are precise, reliable, stable, and above all require low to zero maintenance.

  • Filtering Samples to On-Line Process Analyzers

    Increasingly precise process control strategies, often linked to computer control, have accelerated the use of sophisticated on-line chemical composition analyzers in plant applications. Instruments such as gas and liquid chromatographs, ion chromatographs, laser optic instruments, atomic absorption instruments and specific ion analyzers, which were rarities in laboratories ten years ago, are now found routinely in plant settings.

    While continuing miniaturization and “rugged-ization” of the electronics are making the instrumentation circuitry more tolerant of the plant environment, the level of contamination in plant samples compared to laboratory samples continues to plague the process. This white paper reviews  the factors in plant operation that may affect the deliverability of acceptable samples  and provides guidelines for addressing these factors.

  • TOC Measurement in the Chemical Industry

    The most commonly used compound in the chemical industry is water – not only as a solvent in processing, but also as an energy carrier in the cooling or heating cycle. As vast amounts of water are needed, chemical industries are often located close to large bodies of flowing water. Water used as processing or cooling water is cleaned and subsequently led back to the river or stream. For environmental protection, these waters are subject to specific control and monitoring measures. As the total organic carbon (TOC) non-specifically detects all organic compounds, this parameter has proven to be invaluable here. This booklet introduces a variety of industry-specific applications, and how Shimadzu can provide TOC analyzers to meet specific chemical application needs.

  • Inerting Made Efficient: Replacing Extractive Oxygen Analyzers

    Extractive systems for oxygen measurement in inerting/blanketing applications require a great deal of maintenance. Even if well maintained they are subject to failure due to their complexity. In-line systems based on polarographic probes are far more reliable and require minimal maintenance.

  • Maximizing Power from Biomass

    Implementation of rapid loss on drying and ash analyzers significantly reduces testing times associated with traditional methods, allowing companies to bring products to market faster, increasing production. These features will aide biomass material manufacturers in maximizing control of the market.
