  • 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.

  • Case Study: The Solex Heat Exchanger for Cooling Polypropylene Powder

    Samsung General Chemicals manufactures various petrochemicals and polymers. The cooling step in their polypropylene line was a bottleneck that limited the amount of powder polypropylene that they could produce per year. The PP is used for a wide variety of applications ranging from packaging films to automotive components.

  • What Does It Cost To Own Your Dust Collector Filters?

    When choosing filters for your cartridge dust collector, a Total Cost of Ownership (TCO) calculation allows you to make the most economical and sustainable choice. TCO is a step-by-step evaluation that explores energy use, maintenance and other factors to compare the real costs of operating a dust collector with different filters. This white paper explains how to perform TCO calculations to save money, time and energy.

  • 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.

  • Asking The Right Questions About Cartridge Dust Collection

    Over the past decade, cartridge-style dust collectors have overtaken baghouses as the preferred technology for dust collection in the chemical processing industry. Combining high efficiency filtration with compact size and reduced pressure drop, a high efficiency cartridge dust collector will in most cases be the system of choice.

    Choosing the best cartridge collection system for a given application, however, involves research and attention to detail. This article will review four key areas of investigation. By reviewing these topics with a knowledgeable equipment supplier and knowing the right questions to ask, chemical manufacturing professionals will be better equipped to make informed dust collection decisions.

  • Process Moisture Analysis using FT-NIR

    Manufacturing a pure product can be critically important to the next steps in the manufacture of a powder-based product. As a result the removal of residual moisture and solvents from the crystallization, filtration and drying steps can be crucial to producing a stable product.

  • Chemical Processing Powder eHandbook: Address Challenges Posed by Powders

    One of the trickiest materials to process, powders are comprised of solids or particulates, a continuous gaseous phase (usually air) and, almost always, a liquid component. Many factors influence powder composition including size and distribution, surface roughness and hardness. And, how powders are processed -- vibration, compaction, attrition, segregation -- can influence how powders react. In this Chemical Processing Powder eHandbook, we take a look at how to effectively handle powders, safer dryer operations and how to manage phase changes when processing powders.

  • Chemical Processing Powder eHandbook: Succeed at Solids Handling

    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. Clumping; effective, economical and safe slurry mixing; dust management and dust explosion risk mitigation 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:
    • Clumping – the 10 most common sources of agglomeration in bulk solids and how to effectively manage them
    • Strategies for optimal slurry mixing
    • Level management detection in storage vessels
    • Dust explosion risks – how to identify and mitigate when processing solids
    • Managing solid cohesiveness with flow strategies

  • 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
