I was taught that the word hopefully means “in a hopeful manner” or “full of hope.” Authors who start a sentence with the word hopefully usually mean “I (we) hope” or “it is hoped” — which is an incorrect usage of the word.
A contract welder and a foreman were repairing an agitator support on top of an atmospheric-pressure storage tank. The tank contained a polyvinyl fluoride slurry with a flammable concentration if vinyl fluoride in the vapor space. An explosion...

Not all polymers are useful and/or processable in their natural form. Thus, functional chemicals are added to polymer resins to facilitate processing and to enhance, extend, or otherwise modify the properties of the plastic products manufactured from polymer resins. Such plastic additives represent a $4.6-billion business in the U.S.

Pre-startup actions such as initial water treatment and equipment coatings in cooling tower water systems can increase system life expectancy and efﬁciency, and reduce corrosion and fouling.
By employing the latest virtualization solutions for process control systems, chemical plants can reduce PC hardware requirements, simplify system management, and lower the total cost of ownership, as well as improve site availability, reliability,...
The ﬁeld of chemical engineering is changing — research has expanded into new areas that include bio, nano, and environmental technologies, and career paths taken by chemical engineers after graduation have become more diverse.
Internet-based applications are changing the way chemical engineers collaborate. These virtual tools can help project teams make decisions more quickly, reduce costs, and increase productivity.
Avoid some common pitfalls by taking this holistic approach when implementing projects to reduce the consumption of steam.
Between March and April 2010, a powerful but seemingly limited computer worm, now referred to as Stuxnet, infected computers around the world, beginning in Iran and spreading to Indonesia and India. A recently published book uncovers ﬁndings on the origin of the worm and raises concerns that are relevant to chemical engineers everywhere.
More than 1,500 people died in the most famous maritime disaster in history. Thousands of pages have been written about the loss of the Titanic, and many documentary and ﬁctional movies produced. Many focus on the construction of the ship and the actions of its captain and crew. Whatever the construction and operating issues, attention to one particular issue could have saved many lives — emergency preparation.

They might be more expensive, but there’s probably no need to cancel your party plans just yet. “There’s lots of helium out there” says John Van Sloun, general manager — worldwide helium at Air Products, “but very little of it is being captured because the economics of doing so are not favorable.”
Seven years ago, I wrote a column for another publica tion entitled “The U.S. Chemical Industry: R.I.P.” This pillar of American economic strength, which a few years earlier was the leading exporter among U.S. manufacturing sectors (with net exports of $15–20 billion annually), was shriveling due in large part to policy blunders and regulatory mistakes.
This Beacon is not focused on a single incident, but on incidents that continue to occur across industry — nitrogen asphyxiation.
Actuators automate valves by converting an input signal into motion. This article explains the basics of electric actuator design and explores the different types of electric actuators.
