This 4-page case history by Jeroen van den Berg of Bolz-Summix discusses how changing process conditions within a conical screw dryer eliminated granulation and minimized product segregation.05/02/2006
Manufacturing a pure product can be critically important to the next steps in the manufacture of a powder-based product. As a result the removal of residual moisture and solvents from the crystallization, filtration and drying steps can be crucial to producing a stable product.06/28/2006
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
Combustible dust explosions are a risk in many areas of a chemical plant. Are you in compliance? This white paper reviews the OSHA NEP for combustible dust, NFPA standards on explosion hazards, equipment used for explosion protection, and how to avoid the most common shortfalls to compliance.01/27/2014
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.03/16/2010
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.

Combustible dust explosions are a risk in many areas, but one of the most common locations is the dust collector. This white paper reviews OSHA and NFPA standards, how to identify hazards, and the types of equipment used for explosion protection. It also examines common shortfalls to compliance.09/25/2012
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.03/04/2011

Preventing Phenolic Resin Reactor Accidents: Easy to Use Procedure for Checking Adequacy of Emergency Relief Vent Sizes
An easy to use generalized vent sizing formula is illustrated to be consistent with large scale industry experience and dedicated phenolic runaway reaction tests performed by Fauske & Associates, LLC. The formula also clearly explains the 1999 catastrophic failure of a phenol-formaldehyde reactor resulting from a grossly undersized relief system.06/25/2012
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.
