  • 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.

  • 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.

  • 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

  • CP Powder eHandbook: Effective Powder Processing

    As many chemical processors know, processing powders can be tricky. Powder properties can be affected if the materials are stored for long periods. Powders can be compressed, vibrated, aerated and exposed to moisture. And specific processes like granulation, blending, drying, milling, lubricating and compression put requirements on how powders can be handled. In this Chemical Processing Powder eHandbook, we take a look at how to effectively process powder including:
    • Compression dryers – the case for choosing a solution that produces optimal air quality and low energy consumption
    • GHS – understanding the requirements and what it means to chemicals processors
    • Predicting powder flow behavior
    • Vibratory screen cleaning methods
    • Fine powder flushing - eliminating a common bin-afflicting problem caused by trapped air
    • Tubular Drag Conveying Technology – an alternative to pneumatic conveying
    • Addressing dust hazards – including explosions

  • 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.

  • Chemical Processing’s Powder eHandbook: Tips for Successful Powder Processing

    Powders and the dust they create have a tendency to create a myriad of material handling headaches. For example, dust can wreak havoc on the performance and accuracy of many level sensors, rendering them inaccurate and unreliable. Powder particles under the influence of gravity can become compacted resulting in inter-particle friction that may prevent flow movement. In this Chemical Processing Powder eHandbook, we offer a few tips for optimizing powder processing.

  • Chemical Processing’s Powder eHandbook: Make the Most of Powder Processes

    Powders developed to meet certain product performance targets often suffer from inconsistent and unpredictable flow. The reasons for this are many. A material's characteristics - adhesiveness, cohesiveness, aeratability, pressure-sensitivity - often change during processing and can cause flow problems to crop up. Couple this with changes in the processes themselves and costly downtime can be the result. In this Chemical Processing Powder eHandbook, we take a look at strategies and solutions for overcoming powder processing challenges including:

    • Making the most of flow additives - understand their impact on overall powder behavior to optimize flow
    • Improving performance of gravimetric feeders - tips to avoid poor accuracy and frequent downtime
    • Protecting against combustible dust explosion - economical approaches for protecting spray dryer processes and solutions

    No matter what industry you’re in, chances are you use some form of conveying. Whether it be pneumatic, flexible screw, aeromechanical or other, different conveyors are required to handle different products. But which conveyor is best suited for your operation? Despite the fact that conveyors have been around for almost a hundred years, this question still baffles many industries. In order to choose the right conveyor for your operations, you need to consider your conveyor's use - production, processing, packaging, and you need to consider your business objectives - improve operations? reduce labor?

    In this special report, we look at the different types of conveyors, discuss the use of tubular bag conveyors, and provide 10 tips to prevent a variety of common problems that could occur with pneumatic conveyors.
