Computer-based environmental compliance training offers a number of advantages. This article discusses the benefits of computer-based training, outlines its most important components, and provides tips for structuring and writing a course.
Piping and instrumentation diagrams belong to a family of flowsheets that includes block flow diagrams and process flow diagrams. Technology advances have transformed these resources into intelligent documents, capable of storing layers of digital...
Single-use systems have advanced from a limited product line to several new products for a wider range of unit operations. As these technologies evolve, new size, cost, and regulatory needs continue to fuel industry growth.
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.
Poor design, inadequate maintenance, and improper operation can all lead to mechanical failure. The basic concepts of pressure relief, when understood and applied properly, can help prevent this failure
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.
This article explains how to use layers of protection analysis (LOPA) to evaluate various process safeguards, determine if safety instrumented functions are required, and establish what safety integrity levels are needed to reduce risks to tolerable...
Use Exponential Functions to Correlate Temperature Dependence Asymptotic exponential equations may provide a more-accurate or easier-to-use representation of a property’s temperature dependence than commonly used polynomial expressions.
Recovery has stalled in developed nations. Debt, unemployment, and the emerging recession in Europe will encumber U.S. growth prospects in the years ahead. One bright spot, however, is the shale gas story.
Promising nanotechnology-enabled sensors, monitoring devices and analytical instruments continue to advance toward commercialization for diverse industrial, environmental, medical and military applications— but hurdles remain.
