Use these methods to ensure the flow curve used for engineering design is both accurate and relevant.

Making early estimates of a product's cost components enables developers to manage resources wisely and evaluate the product's economic viability.

Consisting of a flow tube, field-generating coils, electrodes, and a transmitter, a magmeter accurately measures the flowrate of conductive fluids over a wide range of conditions.

By viewing resiliency as a property of complex systems, it may be possible to develop resilient systems that can withstand unanticipated failures without disastrous consequences.

Follow this roadmap to understand the abatement technologies available for controlling emissions of volaitle organic compounds and hazardous air pollutants and the criteria for choosing among them.

Many gloves offer protection from chemicals. This article will help you understand what type of glove can provide the best protection for your application.

The key to low injury and incident rates is creating a work environment that encourages employees to always take action to resolve potential problems. Here's how to do that.

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.

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...

Previously published methods can be tricky to apply and may lead to improperly sized valves. Here is a stepwise, detailed method that more-accurately determines the orifice area.

Understand the economic state of the chemical industry and trends in capital investment to make wise corporate-spending decisions.

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.

These profiles of a dozen engineers in different stages of their careers offer snapshots of where chemical engineers are employed.

Use these graphs and equations to calculate liquid viscosity at any temperature.

Inline direct steam injection is more energy efficient than indirectly heating water in a tank. Use this overview of DSI equipment to select the appropriate system for your application.

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.

In water chemistry control, fluorescent tracing technology can quickly and effectively determine and deal with the root cause of a problem.

Ten lasting chemical engineering achievements — and 100 markers of chemical engineers’ progress toward them.

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...

We as a society should keep these lessons in mind as we set future environmental goals, policies, laws and regulations.

Implement these procedures to consider human factors, not simply human error, in control-room architecture and reduce the chance for incidents in the plant.

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.

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.

Establish an effective monitoring program by following these recommended practices.

Repairing natural gas piping is inherently dangerous. Follow these safety protocols to avoid potentially catastrophic results from improper installation and repair of natural gas lines.

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.

In order to avoid incidents involving reactive chemical hazards, it is useful to understand the types of chemicals and types of equipment involved, as well as the root causes of the incidents.

Tower-related problems can be difficult, time-consuming, and expensive to diagnose and fix. Here’s how to avoid difficulties and improve operating efficiency.

Match the appropriate sensor to the intended application for accurate level measurement.
