  • Continuous Vacuum Filtration Technologies for Sulfuric and Hydrochloric Acid Slurries

    This white paper discusses highly acidic chemical process slurries and the use of continuous vacuum filtration technologies for filtration, cake washing and drying.

    First, the basics and benefits of continuous vacuum filtration technologies are reviewed followed by case-studies. In this first process, the precipitated solids are in sulfuric acid slurry. The challenge is to process 2200 kg/hour of dry solids for filtration, counter-current washing and drying in a contained environment.

    In this second process, the objective is to process precipitated solids in an hydrochloric acid slurry. The white paper concludes with a framework for vacuum technology selection and how this can be applied to other toxic and difficult chemical process filtrations.

  • Dry Media Dust Collector or Wet Scrubber?

    Wet scrubbers and dry media dust collectors are two very different technologies used to capture dusts generated during production processes. Both types have inherent advantages and disadvantages. Which is best for your application? The choice is not always clear-cut, but this white paper will help with the decision process by providing a comparison between wet and dry dust collectors. It will outline general parameters for equipment selection with respect to dust properties including combustibility, explosibility, particle size, moisture and adhesiveness. It will also discuss how to apply NFPA 484: Standard for Combustible Metals, the standard that best addresses wet collection. Though NFPA 484 is specific to metals, some of its content can and should apply to nonmetal combustible dusts.

  • 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.

  • 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.
