  • Tank Blanketing in Hydrocarbon Processing Facilities

    During industrial manufacturing, many companies use a wide variety of chemicals from methanol, acetone and benzene to foodstuffs like wine and edible oils stored in large tanks at different points in the manufacturing process. In a technique called “chemical tank blanketing,” or “padding” nitrogen is commonly applied to protect chemicals stored in tanks against contamination, degradation or chemical change as well as to prevent fire or explosions. This white paper first discusses blanketing basics and benefits. It reviews considerations for tank blanketing  systems and discusses a newer approach, which is typically more  cost effective for most applications, is that of generating nitrogen on-demand in the plant itself.

  • 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

  • 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

  • Powder Processing Best Practices

    A material’s characteristics and how they may change during processing can affect HOW these materials are processed. Key factors affecting powders include aeration, moisture absorption, electrostatic charging to name a few. Many bulk solids are sensitive to heat and humidity. As these levels rise, either in the feeder system or via outside conditions, flow problems crop up. As the powder gains strength, jams and poor flow conditions begin to appear. Costly downtime and a loss of product are incurred while a search is made for a solution to the flow problems. In this Chemical Processing Powder eHandbook, we take a look at key factors affecting powders and today’s best practices for overcoming the processing of powders including:
     

    • Looking beyond the physical properties of particles and treating powder as a bulk entity
    • How scanners take volume to a new level - acoustics-based sensors can help accurately measure the volume of powders in vessels
    • How to determine a coating’s volatile content  - advancements in rapid loss-on-drying techniques significantly reduce testing time
    • Testing powder flow - advances in test methods help better predict flow behavior at elevated temperature and humidity levels

  • Understanding Dust Explosion Dangers

    The unfortunate propensity of dust explosions to destroy entire facilities and claim lives is very real. Powder handling processes often are comprised of interconnected enclosures and equipment. Flame and pressure resulting from a dust explosion can therefore propagate through piping, across galleries, and reach other pieces of equipment or enclosures, leading to extensive damage. In this Chemical Processing Special Report, we take a look at the latest NFPA standards and dust explosion mitigation strategies. This Special Report covers:
     

    • Significant revisions to dust explosion standards – NFPA 654 major changes include new administrative requirements
    • How to defuse dust dangers - carefully consider and then counter risks of fire and explosion
    • Five common dust explosion misconceptions that can lead to a false sense of security

  • Save Money, Time, and Water With Rotary Impingement Tank Cleaning

    Tank cleaning has always been viewed as a necessary evil for manufacturers. During the cleaning process, a significant amount of resources (time, chemicals, water, electric and labor) is required between batches to ensure a reliable, uncontaminated, quality batch is produced. Although these repeating expenditures have a significant effect on the bottom line, many chemical manufacturers continue to rely on outdated processing for cleaning, not realizing the potential opportunity for substantial cost reductions and revenue recovery through CIP optimization.This whitepaper includes specific case studies on the benefits of rotary impingement and CIP optimization vs. the standard tank cleaning processes. These benefits include drastic savings in time and water usage as well as employee safety.

  • Powder eHandbook: Efficient Powder Process Handling

    The mechanisms of powder flow are complex. They are influenced by an array of different parameters; some relate to the particles’ physical attributes, such as size and shape, and others, such as humidity, to the system itself. Although there is a general understanding of these individual mechanisms, the multitude of interactions that govern the specific behavior of a given powder can many and in turn, affect how these powders are processed. In this Chemical Processing Powder eHandbook, we take a look at technologies and strategies for handling powders including:
    • How to Optimize Humidity for Efficient Powder Handling - too much or too little moisture can cause problems during processing and storage
    • How to Select the Right Conveying and Feeding System - successful bulk handling of calcium carbonate depends on a variety of factors
    • Suppressing Explosions for Process Protection - A properly designed and engineered suppression system offers many advantages

  • 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.

  • Mixing Solutions and Slurries -- Effectively, Economically and Safely

    Effectively mixing liquids and solids to create an optimal slurry is one of the perpetual challenges in the chemical industry. This case study demonstrates how an eductor-based mixing system can effectively handle a wide range of materials, utilizing the least amount of floor space, energy and human resources to achieve an optimized process. In addition, the eductor mixing system offers increased efficiencies over a conventional system of mixing by allowing solutions and slurries to be made on demand – as opposed to pre-mixed in large holding tanks. Another important benefit is the system limits exposure to operators, and mitigates issues of delivering solid material in a large vapor space. The design flexibility of an educator-based mixing system offers a high level of customization.
