  • Integrating Process Weighing Data

    Efficient transfer of weighing process data to higher level PLC, MES or ERP systems makes manufacturing processes more efficient and more transparent. But identifying and implementing the most effective system for data transfer and integration can be challenging.

  • Hygienic Feeder Design

    Specifying a hygienic bulk solids feeder is not a simple task. The wide variety of requirements needed for specific applications are similar in scope to explosion proof environmental requirement variations.

  • How Well Do You Know Your Dust?

    The collection and testing of dust samples is a long-established practice used by many powder and bulk processors to make informed dust collection decisions. Dust testing protocols have not changed markedly in recent years. The importance of dust testing, however, has changed, and the implications are significant. While knowing your dust has always been good practice, it is rapidly becoming a necessity in today's regulatory climate.

    This article will review two separate types of testing: (1) explosibility testing, which is used to determine whether a dust is combustible; and (2) bench testing, which pinpoints numerous physical properties of the dust. Both categories of tests are needed to determine the best dust collection system for your application and whether explosion venting equipment must be part of that system.

  • Gas And Dust Explosions -- Relief Sizing Formula

    A large number of analytical and highly empirical correlations including monograms reflecting changing standards have been or are being proposed separately for gas and dust explosion relief venting. This white paper provides a generalized formula that is applicable to both gas and dust deflagrations including subsonic and sonic pressure relief conditions and is consistent with available experimental data and industry experience. Application of the model is illustrated for dust explosions. Download now.

  • eHandbook: Make the Right Moves with Powders

    When designing a system to transport powders and granules there is a wide variety of considerations. Different applications, installation environments, equipment, material characteristics and how they may change during the process are all part of the equation. While many plants aim to keep costs low and often times use old equipment for a new project this can also further compound a complex challenge. And that's not even taking in to consideration our increased awareness of the risks of an explosion and the need to avoid hazardous emissions. In this Chemical Processing Powder eHandbook, we take a look at key considerations affecting today’s best practices for transporting and processing powders and granules including:

    • Installing pneumatic conveyors correctly - 10 steps to prevent a variety of common problems
    • How to understand accuracy in a bin level monitoring system
    • Tubular drag conveying - an alternative to pneumatic conveying
    • Vacuum Conveying equipment and the issues of safety, security and sanitation

  • Drying Compressed Air in Hazardous Atmospheres

    Hazardous locations have or could potentially have high concentrations of flammable gases, vapors, combustible dusts, etc. A small spark can lead to a horrific explosion dangerous to equipment and workers in the area. Equipment located in hazardous areas must be specifically designed to prevent ignition and explosion.

  • Dangers Lie in the Dust - A Chemical Processing Special Report

    The dangers posed by combustible dusts are no longer being swept under the rug. Tougher regulations and greater corporate resolve are making dust hazard management an increasingly important topic for every manufacturing sector including the chemical, food and pharmaceutical industries. This Special Report, brought to you by Chemical Processing details the dangers posed by combustible dusts and includes: the latest thinking on both hazard identification and mitigation; it identifies how to mitigate dust hazards in oral solid dosage facilities; it takes an in-depth look at regulations and the thinking behind suppression technologies as a result of past activity; more!

  • CP Powder eHandbook: Tips for Effective and Safe Handling of Solids

    One of the trickiest materials to process, solids are comprised of powders or particulates, a continuous gaseous phase (usually air) and, almost always, a liquid component. Processors that handle solids know only too well the types of throughput problems that come up on a recurring basis. Effective, economical and safe slurry management; flowability during processing, accurate inventory and volume level management are all very real challenges faced by processors of solids. In this Chemical Processing Powder eHandbook, we take a look at how to effectively handle solids including:
    • Properly accounting for how bulk solids actually will flow in a vessel or overall process -- we take a look at some simple parameters that can often provide a good sense of flowability
    • Strategies for avoiding slurry trouble
    • Mitigating pipe segment force imbalances with Reactor Excursion and Leakage Analysis Program
    • Acoustics-based level measurement for accurate powder measurement in bins, tanks and silos
    • Explosion protection methods including suppression, isolation and venting
