  • Choosing the Correct Emission Control Technology

    Increasingly stringent clean air standards and heightened concerns over greenhouse gas emissions are driving technology enhancements in the chemical processing industry. This white paper explains some of the abatement challenges this industry faces and demonstrates how many chemical processors are integrating newer, more efficient emission control technologies for the destruction of Volatile Organic Compounds (VOCs) and Hazardous Air Pollutants (HAPs).

    The paper also includes a case study, demonstrating how one Pure Terephthalic Acid (PTA) plant saved nearly one million dollars by upgrading to a newer thermal oxidizer technology.

  • Process Filtration Technology: Making Informed Decisions

    Solid-liquid separation is an instrumental part of chemical processing. To separate the solid particles, filter media made of textile or metallic materials and of composite materials are used as the basis for the filter cake. Often there will also be a washing process to improve the purity of the filter cake or to increase the yield of the liquid phase. Solid-liquid separation can be carried out in continuous or batch operation. There are many factors for selecting the right process filtration system for your specific application. This white paper reviews methods for identifying the right process filtration technology for your application and highlights case studies illustrating the methods discussed.

  • 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

  • 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.

  • 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.

  • 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.
