Process Plant Layout — Becoming a Lost Art?

Plant layout is as important a part of process plant design as it ever was, but it is rarely taught as part of chemical engineering courses While process plant layout is a critical aspect of chemical process industries (CPI) operations,…

Pump Safety: Flirting with Disaster

Be vigilant about parallel pumping conditions that can lead to catastrophic failures During my career, I have seen several massive centrifugal pump failures caused by pump users attempting to operate pumps in parallel without the proper equipment review, procedural review…

Considering Fugitive Emissions During the Conceptual Design Stage

The ability to reduce fugitive emissions through the use of strategic design modifications not only protects workers and the environment, but reduces losses of valuable process materials The industrialized nations of the world have all placed increased emphasis on the…

Cybersecurity: You Cannot Secure What You Cannot See

Follow this guidance to understand today’s cybersecurity risk landscape and take the necessary steps to create a sound industrial control system cybersecurity program, including the development of a comprehensive, in-depth cyber-asset inventory In industrial facilities, cyber incidents typically result from…

Using Excel VBA for Process-Simulator Data Extraction

Engineers can make better use of the results of process simulations by automatically exporting data into heat and material balance tables in Microsoft Excel Chemical engineering projects require process simulation to validate the chemical reactions and mechanical operations of the…
