Inerting and Blanketing: New Cost-efficient Solution with Polarographic Sensors
In this white paper, we review the new possibilities offered by measurement systems based on polarographic technology. Unlike other systems, polarographic sensors are built directly into the process gas stream, eliminating the need for cumbersome gas sampling and conditioning systems. Further, polarographic sensors require very little maintenance.
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.
Asking The Right Questions About Cartridge Dust Collection
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.

How Well Do You Know Your Dust?
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.
Unwelcome oxygen Tank blanketing is the process of filling the headspace in storage vessels and reactors with an inert gas to prevent its contents from exploding, degrading or polymerizing and to protect equipment from corrosion. A blanketing system is normally designed such that it operates under higher than atmospheric pressures, therefore preventing outside air from entering the vessel. As oxygen and moisture in the air can be undesired in numerous processes and applications, blanketing is done in a wide range of industries, varying from (petro)chemical to food and beverage, pharmaceutical to pure water.
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.
Rectifier design for fuel ethanol plants reduces energy
Plants have traditionally used trays in the distillation columns to produce fuels grade ethanol. Trays of various configurations have been adequate in this service and their technology is well founded. The ever-present desire to reduce the energy needed to produce a gallon of ethanol has opened the doors to structured packings being used in the rectification sections of ethanol distillation columns.

Process Moisture Analysis using FT-NIR
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.
Preventing Segregation During Powder Drying
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.
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.
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.
Hygienic Feeder Design
Specifying a hygienic bulk solids feeder is not a simple task. The wide variety of requirements needed
for specific applications are similar in scope to explosion proof environmental requirement variations.
