RFID in Manufacturing
In the wake of a Wal-Mart mandate requiring top suppliers to put Radio Frequency Indentification (RFID) tags on cases and pallets of consumer goods by January 2005, Rockwell Automation offers this white paper to help educate manufacturers on how to maximize their investment in RFID technology throughout their enterprise and supply chains. The paper provides a practical guide to extracting measurable value from RFID implementations in plant and warehousing operations.
Risk-Based Process Safety Design
Safe design has long been a priority in the process industries. A safe design basis, together with a formal safety management system and safety practices, procedures, and training, is critical for providing that level of confidence required for risk management. The goal of process safety management is to consistently reduce risk to a level that can be tolerated by all concerned. A systematic, risk-based approach to safety design can help eliminate hazards that pose intolerable risk from the process and mitigate the potential consequences of hazards.
Succeed at Dynamic Modeling of Batch Reactors and Batch Distillation
This paper reviews the basic techniques for dynamic modeling of these two key operations. It covers considerations related to heat transfer, reaction chemistry, mass balances and the control system. It also discusses equipment configurations, performance characteristics and operational constraints.
Tracing the accuracy of calibration gases
Calibrating your instruments using specialty gas will only yield results as accurate as your gas mixture. This three-page white paper discusses analytic traceability and how it relates to gas mixture accuracy.
Permit-Required Confined Spaces
This new U. S. Occupational Safety and Health Administration paper describes OHSA's confined-space satndard, and discusses how to meet it by controlling hazards, administering entry permits and assigning duties, as well as how to deal with emergencies and OSHA assistance available.
Design Tips for Admittance Probes
This white paper from Delta Controls outlines a range of selection and installation criteria for using admittance probes to monitor the level of powders, liquids and other materials. Dielectric constants of more than 200 common industrial materials are included.
Push Maintenance: The New Frontier in Asset Management
The convergence of innovative technologies using open industry standards simplifies communication between software and technology. Now you can centralize key performance diagnostics, push critical information to the workforce, and problems can be solved from anywhere.
How to Choose a Vacuum Dryer
Vacuum drying can be applied in a range of processes in several industries, including chemical, pharmaceutical, food, plastics, and metal powders. This article first discusses vacuum drying benefits and limitations and dryer components and operation, then explains the differences between tumble and agitated vacuum dryers and how you can select one for your application.
Design Guidelines for Distillation Columns in Fouling Service
This 33-page paper discusses the wide variety of factors that can cause fouling and the impact of this fouling on the performance of a distillation column. It then provides details on practical methods for mitigating fouling, including equipment design, surface treatment, and use of additives.
Understanding Regulated Health and Safety Standards--Part 1
This paper provides the viewpoint of the American Conference of Governmental Industrial Hygienists (ACGIH), a private not-for-profit, non-governmental corporation open to all industrial hygienists or other occupational health and safety professionals. The authors have the opinion that there are misunderstandings about the use of regulated health and safety standards.
In part one of this article, they provide some information on how regulations are formed and advice on using these values to conduct business. Employers and employees need this fundamental understanding to make informed health and safety decisions. This information is also useful for guiding public decisions about everyday toxic exposures.
Accurate liquid phase density on aerated liquids
This white paper discusses SONAR-based, clamp-on gas volume fraction meters which recently have been introduced to the industry that provide an accurate, real time, measurement of entrained gases. Coupling entrained gas volume fraction monitor with most types of process density meters, enables accurate determination of liquid and the liquid-solid components of aerated mixtures.
Special Report: Chemical Industry Sees Green
For years the industry has been talking green. But what real strides have been made? Will a Presidential Executive Order compel the industry to speed up efforts to actually go green? While pollution prevention was the original goal of green chemistry, todays efforts promise to have a substantial economic impact. This Special Report will bring you up to speed on fruitful efforts to go green including an update on the growing interest in bio-based feedstocks.
Intelligent Rotary Control Valve
NELES rotary control valves with Q-Trim have greater capacity than comparable globe-style linear valves with noise reduction trims widening rangeability, reducing weight and valve dimensions, and a 50% cost reduction compared to linear valves of comparable Cv. NELES rotary control valves from Metso Automation. Intelligent Reliability leads to Intelligent Results.
