Feature Reports Compilation Guidebook – 2018



Chemical Engineering’s Feature Reports provide concise, factual information that aids in solving real problems. The practical, how-to orientation of these articles ensures that they can be directly applied to chemical engineers’ daily jobs. Each story applies to a relatively broad section of the chemical process industries as opposed to focusing on just one niche.

All 2018 articles are compiled into this one convenient location.

Delivered in a PDF format, 194 pages.

Articles include:
