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?10/22/2004
Many industrial plants use dissolved air flotation to remove fats, oils and grease, and suspended solids from wastewater. Chemical additions are often kept higher than necessary to account for variations in influent water quality that are characteristic of industrial facilities. Continuous monitor04/02/2013
Flexible Intermediate Bulk Containers (FIBCs) have found their niche in the worldwide transportation of powdered, flaked and granulated products. FIBCs are typically made of woven plastic with some type of liner insert and are often referred to as super sacks, big bags or bulk bags in industry. During filling and emptying of FIBCs there is a steady accumulation of static charge that can result in electrostatic discharges from the FIBC. This may in turn provide sufficient energy for ignition of combustible particulate solids or flammable vapors, not to mention unsettling shocks to nearby personnel. In this white paper we review the NFPA 654 Standard for the Prevention of Fire and Dust Explosions from Combustible Particulate Solids and the importance of why identifying the Minimum Ignition Energy (MIE) of your combustible dust or flammable vapor is a necessary component for selecting the correct FIBC Type for your application.

Industrial automation is no longer limited by the walls of a production facility. More and more automation is being handled via remote communication, whether its from the office or from the comfort of your own home. Todays PLCs give you the ability to access your control system to handle such tasks as monitoring via a website to determine the condition of a machine or check other statistics.04/24/2006
Many companies have invested heavily in mission-critical business software initiatives. Much time and effort has gone into deploying sophisticated customer relationship management solutions, adaptive supply chain software, ambitious data migration projects, and other endeavors. All too often, however, these worthy but expensive initiatives fail to deliver anticipated benefits because theyre hobbled by poor data.

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
Calibration of weighing equipment is one of the most important activities within any quality management system. But is a passed calibration enough?
This white paper from Mettler Toledo explores the difference between calibration and adjustment. Uncover why the true value of calibration lies in assessing according to your own tolerances. Learn how to improve your weighing processes by identifying your safe weighing range and how to prevent poor product quality due to weighing devices.12/07/2016
Today’s global challenges — climate change, water scarcity, food provision, declining ecosystem services, human development, and the overall transition to a sustainable society and planet — require solutions of unprecedented scale. Public policy and behavior change will play a significant role in addressing these challenges. So, too, will business and technology. In the decades ahead, these challenges offer tremendous opportunity for organizations that can contribute to tackling them.
This Chemical Processing eHandbook takes a look at how chemicals manufacturers are meeting these challenges head on. Download this Chemical Processing eHandbook for insights and strategies including:
- How organizations such as Dow, Solvay, Dupont and BP are adapting strategies for their water conservation efforts;
- How a new purification process that’s carbon-negative and energy-positive can save energy;
- Why sustainability metrics spur product development efforts to improve conservation efforts

Corrosion and premature piping failure are two problems that plague chemical piping applications everywhere. Metallic systems are necessarily limited in their life spans by corrosion concerns, and operations managers must always face the question of when their pipes will eventually need repair or replacement. Polymer piping systems have made great strides across multiple industries in the past few decades, and investigating the benefits that can be realized by making the switch from metallic systems can help to bring unexpected value to many applications.
This paper will specifically evaluate the benefits of polymer piping systems in three industries: power generation, chemical processing, and mineral processing.09/22/2014
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.10/22/2004
The unfortunate propensity of dust explosions to destroy entire facilities and claim lives is very real. Powder handling processes often are comprised of interconnected enclosures and equipment. Flame and pressure resulting from a dust explosion can therefore propagate through piping, across galleries, and reach other pieces of equipment or enclosures, leading to extensive damage. In this Chemical Processing Special Report, we take a look at the latest NFPA standards and dust explosion mitigation strategies. This Special Report covers:
- Significant revisions to dust explosion standards – NFPA 654 major changes include new administrative requirements
- How to defuse dust dangers - carefully consider and then counter risks of fire and explosion
- Five common dust explosion misconceptions that can lead to a false sense of security
