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
- Vacuum Conveying equipment and the issues of safety, security and sanitation

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.02/24/2012
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.04/28/2016

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

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
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.10/18/2016
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.08/12/2013

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
