Use this step-by-step procedure to apply safety instrumented systems (SISs) and continuously reduce risk.
Salvaged, remanufactured, refurbished or new-surplus equipment may be a cost-effective option. Here's how to recognize when such devices may no longer meet safety or regulatory requirements.

While chemical companies work toward complying with existing standards, legislators are poised to revise those very rules — with changes ranging from minor tweaking to major overhaul on the table.
This special products section looks at some of today’s equipment and service offerings alongside product write-ups and ads from the past.
A properly selected, configured and installed fire and gas safety instrumented system can reduce a facility's risk and maintain operational integrity.

Ignoring this hidden hazard can put both the public and companies that operate cooling towers at risk.
Some pharmaceutical companies are turning to radio frequency identification to protect against counterfeiting and theft of expensive drugs.
These automation tools help equipment vendors serve their customers better, support their sales force, and profit in many ways.

Many technology advances are underway to address cost, CO2 and reliability issues and expand the use of integrated gasification combined cycle (IGCC), a cleaner way to generate electricity from coal.
Suzanne A. Shelley
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.
Frank F. Liserio Jr.
Incorporating hurricanes, earthquakes and other forces of nature into an integrated process safety management (PSM) program can enable you to effectively identify these hazards and manage the risks.
R. Russell Rhinehart
By understanding the normal enrollment swings, employers and students can capitalize during the boom times and rideout the busts, while universities can allocate resources more effectively.
Ten lasting chemical engineering achievements — and 100 markers of chemical engineers’ progress toward them.
The first annual World Science Festival takes Manhattan by storm, with 120,000 people celebrating scientific diversity.
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.
Robert J. Conroy, Umesh Mathur, Robert D. Rounding, Daniel R. Webb
This methodology, based on steady-state and dynamic simulation, can be used to develop the necessary models— and avoid disruptive and costly step testing to the extent feasible.
Kristin M. Malosh
Achieving and maintaining ISO 14000 certification for an environmental management system (EMS) is a difficult task that can be made easier by following these suggestions.
Tomas B. Co
Dynamic process modeling based on non-uniformly sampled data and multiple sampling runs, even for nonlinear systems, can be performed using spreadsheet implementations of the weighted-least-squares (WLSQ) and Runge-Kutta WLSQ methods.
Rising gas prices and climate uncertainty have thrust energy and environmental policy to the forefront of modern American politics.
Travis W. Walker
Before solar and wind energy can be widely exploited, a method for storing the energy provided by these intermittent sources and releasing it as demand arises must be developed.
