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
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. Clumping; effective, economical and safe slurry mixing; dust management and dust explosion risk mitigation 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:
Clumping – the 10 most common sources of agglomeration in bulk solids and how to effectively manage them
Strategies for optimal slurry mixing
Level management detection in storage vessels
Dust explosion risks – how to identify and mitigate when processing solids
Managing solid cohesiveness with flow strategies

In chemicals processing, significant hazards exist -- such as those from fire, explosions or toxic release. The processes themselves, the chemicals being processed and the procedures followed, or lack thereof, can all contribute to the risk exposure of these hazards. What can processors do to mitigate these risks? For chemicals processors, it's crucial to implement processes and solutions to detect and prevent these hazards from occurring in the first place.
Chemical Processing has taken an in-depth look at plant safety -- how to identify the hazards and implement processes and procedures to ensure a safer working environment. This comprehensive Chemical Processing Special Report titled: Improve Plant Safety is now available to download for free.
A large number of analytical and highly empirical correlations including monograms reflecting changing standards have been or are being proposed separately for gas and dust explosion relief venting. This white paper provides a generalized formula that is applicable to both gas and dust deflagrations including subsonic and sonic pressure relief conditions and is consistent with available experimental data and industry experience. Application of the model is illustrated for dust explosions. Download now.
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.
In March 2008, OSHA reissued its Combustible Dust National Emphasis Program (NEP) notifying approximately 30,000 companies nationwide that they will be targeted for inspections over the next few years. Mettler Toledo recognizes that many manufacturers are not up-to-date on the latest hazardous area compliance regulations or may not know that their industry is subject to those regulations. Don't wait until your facility receives a surprise visit from OSHA or worse yet, for a catastrophic incident to occur. Take the proactive approach to addressing the "hazardous area advisory level" in your facility.
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.

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.
Fine powders present problems that bulk solids do not when they are contained in a bin, hopper or processing vessel. The primary problem is the powder's flow pattern. This 10-page PDF whitepaper discusses solutions to this problem.
This 26-page white paper from Monitor Technologies discusses the difficulties in measuring bulk solids and powders in bins, silos and hoppers. Download this document to learn which technologies are out there that can make this job easier.
