This 6-page primer explains the various forms of nonwoven media, their special characteristics, as well as filter configurations and function. It discusses advantages and disadvantages, and application trends.
Process control vendors are migrating plant control technologies to more open network and operating environments. This White Paper explains how layered security can be accomplished by adopting a "best practices" model, developing and implementing an access control plan, and compartmentalizing the network.
This 8-page primer describes a method for identification of major acute risks in existing process facilities that can potentially affect on-site and off-site populations and for prioritization of mitigation methods.
Most companies have completed at least three process safety management(PSM) compliance audits of their covered facilities since the promulgation of the OSHA PSM standard. These companies, however, are not seeing noticeable improvements in their PSM programs. In fact, many companies feel that their PSM programs have become less effective. What has happened and why? Are there any lessons learned from the Enron collapse and its auditing program? What needs to be done?
A global manufacturing company needed to transfer data from their plant in Detroit, Michigan to a process data storage system in St. Paul, Minnesota. Their Control Systems Engineering Group chose OPC technology as the communication medium.
Many catalytic reactions rely on platinum, palladium and other precious metal catalysts. When the activity of the catalyst declines to the point that it must be replaced, the used catalyst can be sent to a refiner to recover precious metal. This 8-page paper discusses the variouis factors that should be considered when using a refiner.
The design of the expansion tank plays an important role in the successful operation of a heat transfer system using organic fluids. It can contribute to longer fluid life and lower maintenance. This paper describes the proper sizing, piping and valving, instrumenting, and inerting of the tank.
Manufacturers of heat transfer fluids assign a maximum temperature rating to each fluid. This rating must be considered to ensure the safe and efficient operation of the fluid. This paper explains the basis of the rating, how fluids degrade, and how the temperature profile in a heat transfer system affects fluid performance and life.
