This guidance applies to reactive systems subject to fire-induced runaway reactions, tanks that store reactive materials, and two-phase flow of reactive materials.
Increasingly, project managers are called upon to employ laser scanning technology. However, little information available to aid with its specification. This article discusses the basics of laser scanning and the parameters that should be included...
As businesses strive to improve productivity, process modeling can be a powerful tool. This article explores the role of modeling in enhancing the effectiveness and efficiency of process development and manufacturing.

OSHA-mandated hearing conservation programs reduce incidents of noise-induced hearing loss. Here's how to select the appropriate personal protective equipment.
Nearly 1,300 members responded to our online questionnaire about the future of chemical engineering. Here’s what they said.
Noncontacting infrared thermometers can be used in many applications that are too harsh or impractical for thermocouples and resistance temperature detectors. Understand their principles of operation and their advantages and limitations to select...
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.
Reviewing incident reports at a HAZOP meeting is more than just a lessons learned activity. It can spur sharper thinking and lead to a more telling analysis of your processes.
Determining maximum capacity and ensuring that permit limits are federally enforceable are critical to calculating PTE.

The increased complexity of security systems may come at the expense of the user. Thus, they must be designed to match their operators' capabilities and limitations.
Innovative advances continue to benefit all three of today's air separation technologies, helping to reduce power consumption and capital costs, and, in turn, expand their markets.

This article demonstrates that the repair and expense costs of process trains are not proportional to their capital costs and that, in most cases, building one plant with a single process train is the most economically efficient choice. <br>...
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.

Age and life are not suitable parameters to compare catalyst performance. The proper ones are the rate of reaction and the rate of deactivation.
