  • 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 flowability - how new measurement methods now make it easier to evaluate flow
    • Process safety -  properly designed weigh model can optimize safety and improve efficiency
    • A multivariate approach to powder processing -  an overview of several methods that can help determine which powder properties have the greatest influence on performance

  • eHandbook: Take the Pressure Off Your Process

    When thinking of the processing of chemicals, we think of any activity including storing, using, handling, manufacturing, or moving chemicals at a site, and any combination of these activities. A common state in many of these activities is the flow - or rate - at which the chemicals are moving through a process. Accurately measuring flow can be a challenge for many chemical processors since so many factors can influence the chemical properties and subsequently the  rate of flow. In this Chemical Processing Pressure eHandbook, we discuss considerations for flow management including:

    • Pressure transmitters -  how noise can pinpoint process problems
    • The use of orifice plates -  how insufficient flow conditioning often undermines measurement accuracy
    • Robust Inferential Sensors - easier-to-develop-and-maintain sensors offer significant benefits for chemical processes

  • 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.
