In chemical production and processing, process design and process safety are crucial considerations – especially when powders are part of production and processing. Inherent challenges such as increasing throughput, accurately measuring powders to manage inventory and removing excess solvents are all challenges that chemical processors need to contend with. In this Chemical Processing Powder eHandbook, we take a look at these powder processing challenges and identify solutions and strategies to overcome them. Learn more about:
- Vacuum conveying - customization, automation and safety

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

Process design and process safety are critical considerations in chemical production and processing. With design and safety paramount at the outset of any new development or equipment retrofit, firms can minimize risk exposure, maximize productivity and position themselves to remain compliant and competitive. Whether retrofit or new, chemical processing is continually challenged by combustible dust. Combustible dust can pose a hidden hazard when accumulation occurs in unseen locations such as in mechanical spaces, above false ceiling, ventilation systems and dust collection systems. In this Chemical Processing Powder eHandbook, we take a look at strategies and solutions for mitigating combustible dust hazards including:
- Identifying hidden hazards - a case study outlining how a facility finds danger from accumulated dust and effectively addresses it
- Powder flowability - how new measurement methods now make it easier to evaluate flow
- Process safety - properly designed weigh model can optimize safety and improve efficiency
- A multivariate approach to powder processing - an overview of several methods that can help determine which powder properties have the greatest influence on performance

- Understand Powder Flow Characteristics: a powder’s variables and external factors will greatly impact blender size and type.
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

This article discusses process filtration approach developed for each technology stage starting from batch filtration in the lab to continuous filtration for the full-scale commercial operation. Process engineers must not “jump to conclusions”, a reference from Sherlock Holmes and Dr. John Watson who prove time and again is that there is no benefit to jumping to conclusions. Therefore, laboratory / bench top filtration testing is covered for problem analysis, technology selection and pilot and demonstration scale-up. The paper continues with the filtration testing and then scale-up to the commercial size. Finally, the paper concludes with a general review of the problem-solving skills of Holmes and Watson and how these skills can be utilized by process engineers as a framework for “idea-generation” when analyzing a new process scale-up.06/02/2015
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.02/25/2014
