Fluids and Solids Handling

Jesse Yoder

This effective approach to flowmeter selection involves a step-by-step method that begins by matching the application with the flowmeter(s). Then, a series of criteria are applied to narrow the selection.

Tools to Model Multiphase Separation

Fluids and Solids Handling

David Connolly, Saeid Mokhatab, Timothy Newton

The flow fields in multiphase separators are often extremely complicated, making it difficult to model such systems. Computational fluid dynamics (CFD) and visual dynamic modeling (VDM) can be used together to overcome some of the challenges.

Chem Economics

T. Kevin Swift

Not all polymers are useful and/or processable in their natural form. Thus, functional chemicals are added to polymer resins to facilitate processing and to enhance, extend, or otherwise modify the properties of the plastic products manufactured from polymer resins. Such plastic additives represent a $4.6-billion business in the U.S.

Chem Economics

Martha Gilchrist Moore

The terrorist attacks that occurred on September 11, 2001, changed the world and forever altered the way American chemistry conducts business. While improving facility security is not a new endeavor for chemical companies, the industry has increased...

Spreadsheet Problem-Solving for ChemEs

eLearning (online) Course

This eLearning course provides instruction for using Excel for a wide range of spreadsheet applications and skills relevant to practicing chemical engineers.

Integrated Process Synthesis

In-Company Training

As a chemical engineer, before you can make proposed process alterations you must consider the potential investment return. Yet, typically this involves detailed simulations and design work. Join process synthesis and integration experts Diane Hildebrandt and Bilal Patel and learn novel design and analysis techniques you can implement early on to avoid costly revisions to processes while reducing material and energy consumption and carbon dioxide emissions.
