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.

Issues such as sterility, isolation and contamination must be considered when choosing seals for use in biotech and pharmaceutical processes. This overview describes common types of seals and offers guidance on selecting the appropriate seal for...
Engineers typically don’t learn the “soft skills” of team and project management in school. Here is a game plan to help you supplement your technical expertise with effective leadership.

Understanding when and why mixing fails in the laboratory is often the only way of avoiding a similar failure in a production-scale reactor. Here we examine mixing in stirred-tank reactors and provide guidance on scale-up.

This article introduces a novel approach to solving flow and pipe-sizing problems based on two new dimensionless quantities that are independent of line size and flow.
Robert J. Fisher, Thomai Panagiotou
This continuous bottom-up approach allows precise control of the crystallization process to achieve size, distribution and quality goals, as well as realize the benefits of process intensification.
