Design Tips for Sensing Probes
This application note from Delta Controls outlines selection and installation criteria for using admittance probes to monitor the level of powders, liquids and other materials. Dielectric constants of more than 200 materials are included.
Preventing Phenolic Resin Reactor Accidents
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.
Gas And Dust Explosions -- Relief Sizing Formula
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.

Dangers Lie in the Dust - A Chemical Processing Special Report
The dangers posed by combustible dusts are no longer being swept under the rug. Tougher regulations and greater corporate resolve are making dust hazard management an increasingly important topic for every manufacturing sector including the chemical, food and pharmaceutical industries.
This Special Report, brought to you by Chemical Processing details the dangers posed by combustible dusts and includes:
the latest thinking on both hazard identification and mitigation; it identifies how to mitigate dust hazards in oral solid dosage facilities; it takes an in-depth look at regulations and the thinking behind suppression technologies as a result of past activity; more!
Use CFD to Improve Crystallization | Chemical Processing
In this article, Kumar Dhanasekharan, Ph.D., technical specialist with the computational fluid dynamics (CFD) specialist Fluent, Inc., shows how modelling crystallizers using CFD can help improve process understanding, control crystal size distribution (CSD) and improve pharmaceutical crystallization results.
Chemical Processing Special Report: Conveyors
No matter what industry youre in, chances are you use some form of conveying. Whether it be pneumatic, flexible screw, aeromechanical or other, different conveyors are required to handle different products. But which conveyor is best suited for your operation? Despite the fact that conveyors have been around for almost a hundred years, this question still baffles many industries. In order to choose the right conveyor for your operations, you need to consider your conveyor's use - production, processing, packaging, and you need to consider your business objectives - improve operations? reduce labor?
In this special report, we look at the different types of conveyors, discuss the use of tubular bag conveyors, and provide 10 tips to prevent a variety of common problems that could occur with pneumatic conveyors.
Particle Image Understanding A Primer
This paper will discuss the use of pattern recognition techniques to identify and differentiate different particle types contained in a heterogeneous solution. This application involves imaging the microscopic particles in real-time as they flow in a solution, segregating each individual particle as a separate image, and then applying pattern recognition techniques to differentiate the individual particle types.A framework for discussing the complexity of a pattern recognition operation in this application will be proposed, along with some specific examples showing how this framework applies.

7 Applications You Didn’t Know Were Compatible with Microwave
Microwave energy in chemical processing has really come of age over the past few years. Many companies are experiencing the benefits that microwave offers over conventional drying technologies. Other functions include: sterilization, pasteurization, cooking, tempering, dehydration and heating.
While you may have guessed a few of the applications we’re profiling, or may even work with them yourself, we hope at least one or two applications off our list will catch your eye and perhaps start you thinking.
• Analytical Chemistry
• Treatment of Biomass & Biosolids
• Powder Processing
Animal Blood Plasma
• Pyrolysis for Recycling & Waste-to-Energy

OSHA & NFPA Compliant: Keeping Your Plant Safe
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.
Integrating Process Weighing Data
Efficient transfer of weighing process data to higher level PLC, MES or ERP systems makes manufacturing processes more efficient and more transparent. But identifying and implementing the most effective system for data transfer and integration can be challenging.

Drying Compressed Air in Hazardous Atmospheres
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.
Aseptic PAT and Particle Monitoring
In this white paper, Mark Hallworth, pharmaceutical manager for Particle Measuring Systems, discusses continuous monitoring methods, how theyre evolving, and why theyre important.
