Many industrial gases are transported, stored and used in liquid form, a situation that poses significant health and safety risks. This one-page reference highlights good safety practices for preventing personnel injury when working with cryogenic fluids. High-purity industrial gases, including nitrogen, oxygen, helium, argon and other noble gases, are commonly generated by air-separation units (ASUs)...

Water scarcity is one of the most serious global challenges of our time. Desalination and water reuse are effective and reliable means to provide new water resources. Among the many methods available to treat water, reverse osmosis (RO) has widely demonstrated superior reliability and cost-effectiveness at removing dissolved species, such as salts and trace contaminants. This article reviews the...

Leaks in a chemical process industries (CPI) facility can run the gamut from creating a costly waste to prefacing a catastrophic failure.. They can be an annoyance, by creating pools of liquid on concrete that can become a possible slipping hazard and housekeeping problem, or a leak that can emit toxic vapors, causing various degrees of harm to personnel. In some cases a leak may be a simple housekeeping...

Large petroleum-refining complexes often have dozens of fired heaters, making broad-based competency in this area essential to overall reliability, safety and energy efficiency. Despite industry’s widespread familiarity with fired heaters, they continue to pose significant challenges during initial control-system design and unless properly specified, operated and maintained, fired heaters can hinder...

"As long as fossil fuels and carbon-intensive industries play dominant roles in our economies, carbon capture and storage (CCS) will remain a critical greenhouse gas reduction solution. With coal and other fossil fuels remaining dominant in the fuel mix, there is no climate friendly scenario in the long run without CCS." So begins the 2013 edition of the Technology Roadmap — Carbon Capture...

When flammable or combustible atmospheres are present, uncontrolled discharges of static electricity are potentially dangerous or even catastrophic. A significant portion of industrial explosions and fires are attributable to static electricity each year. In theory, controlling static electricity by grounding potential sources is simple, but in practice, doing so effectively requires thorough knowledge of...

Big-time security threats and breaches, like the recent Target data breach involving confidential consumer information, remind us of how vulnerable our interconnectivity makes us. And yet, the advantages of the technological advances that we enjoy are so many that there is no turning back. In his keynote presentation at the recent ARC Industry Forum (February 2014; Orlando, Fla.; www.arc.com), ARC Advisory...

About thirty years ago, my golf foursome learned an important safety lesson and we credited the Dalai Lama. We were all big fans of the movie “Caddyshack.” In that movie, Bill Murray’s character talks about caddying in the Himalayans for the Dalai Lama and states, “So I’m on the first tee with him. I give him the driver. He hauls off and whacks one — big hitter, the Lama...

The chemical process industries (CPI) are, by their very nature, global in scope. While chemical process operators share many common aspects (in terms of the use of chemical engineering unit operations), the location of their operation brings about different requirements when it comes to managing gaseous and particulate pollutants, because different countries have different regulations with regard to air...

Polymers like polyethylene, polypropylene, polyvinyl chloride and polyester have become ubiquitous in manufacturing. The properties of polymer-based materials that make them so desirable — they are generally cheap to produce and boast high chemical and thermal stability — also make them abundant, disposable and, in many cases, non-degradable. As landfill space decreases, and with some European...

As an owner or manager of a company whose product is regulated by the U.S. Food and Drug Administration (FDA), you will, at some point, be subjected to an FDA inspection. And once an inspection is underway in your facility, anything affecting the drug or food product directly or indirectly in an adverse manner is within the purview of the FDA inspectors. If discrepancies are found during such an...
