  • OSHA & NFPA Compliant: Keeping Your Plant Safe

    In March 2008, OSHA reissued its Combustible Dust National Emphasis Program (NEP) notifying approximately 30,000 companies nationwide that they will be targeted for inspections over the next few years. Mettler Toledo recognizes that many manufacturers are not up-to-date on the latest hazardous area compliance regulations or may not know that their industry is subject to those regulations. Don't wait until your facility receives a surprise visit from OSHA or worse yet, for a catastrophic incident to occur. Take the proactive approach to addressing the "hazardous area advisory level" in your facility.

  • Particle Image Understanding – A Primer

    This paper will discuss the use of pattern recognition techniques to identify and differentiate different particle types contained in a heterogeneous solution. This application involves imaging the microscopic particles in real-time as they flow in a solution, segregating each individual particle as a separate image, and then applying pattern recognition techniques to differentiate the individual particle types.A framework for discussing the complexity of a pattern recognition operation in this application will be proposed, along with some specific examples showing how this framework applies.

  • Powder eHandbook: Efficient Powder Process Handling

    The mechanisms of powder flow are complex. They are influenced by an array of different parameters; some relate to the particles’ physical attributes, such as size and shape, and others, such as humidity, to the system itself. Although there is a general understanding of these individual mechanisms, the multitude of interactions that govern the specific behavior of a given powder can many and in turn, affect how these powders are processed. In this Chemical Processing Powder eHandbook, we take a look at technologies and strategies for handling powders including:
    • How to Optimize Humidity for Efficient Powder Handling - too much or too little moisture can cause problems during processing and storage
    • How to Select the Right Conveying and Feeding System - successful bulk handling of calcium carbonate depends on a variety of factors
    • Suppressing Explosions for Process Protection - A properly designed and engineered suppression system offers many advantages

  • Powder eHandbook: Preclude Powder Problems

    Process design and process safety are critical considerations in chemical production and processing. With design and safety paramount at the outset of any new development or equipment retrofit, firms can minimize risk exposure, maximize productivity and position themselves to remain compliant and competitive. Whether retrofit or new, chemical processing is continually challenged by combustible dust. Combustible dust can pose a hidden hazard when accumulation occurs in unseen locations such as in mechanical spaces, above false ceiling, ventilation systems and dust collection systems. In this Chemical Processing Powder eHandbook, we take a look at strategies and solutions for mitigating combustible dust hazards including:

    • Identifying hidden hazards - a case study outlining how a facility finds danger from accumulated dust and effectively addresses it

  • Powder Processing Best Practices

    A material’s characteristics and how they may change during processing can affect HOW these materials are processed. Key factors affecting powders include aeration, moisture absorption, electrostatic charging to name a few. Many bulk solids are sensitive to heat and humidity. As these levels rise, either in the feeder system or via outside conditions, flow problems crop up. As the powder gains strength, jams and poor flow conditions begin to appear. Costly downtime and a loss of product are incurred while a search is made for a solution to the flow problems. In this Chemical Processing Powder eHandbook, we take a look at key factors affecting powders and today’s best practices for overcoming the processing of powders including:
     

    • Looking beyond the physical properties of particles and treating powder as a bulk entity
    • How scanners take volume to a new level - acoustics-based sensors can help accurately measure the volume of powders in vessels
    • How to determine a coating’s volatile content  - advancements in rapid loss-on-drying techniques significantly reduce testing time
    • Testing powder flow - advances in test methods help better predict flow behavior at elevated temperature and humidity levels
