Overcome the challenge of corrosion
Article Abstract:
Corrosion or the deterioration of material, typically metal, because of reaction with its environment, is a constant danger which practicing chemical engineers must always watch out for since it can lead to structural or equipment failures, some of which may be catastrophic. Some practical examples will demonstrate a number of typical pitfalls that lead to some of the more, or less, common forms of corrosion that can occur, given certain combinations of material and environment. It is argued that what is not always appreciated are the circumstances of an environment.

Switch materials to prevent pollution
Article Abstract:
Material substitution is one approach to preventing pollution during the processes involving chemicals, including petroleum processing, chemical manufacturing, surface cleaning, natural gas sweetening and surface coating applications. The approach involves replacing hazardous substances with materials that are less harmful to humans and the environment. For it to be successful, chemical engineers must be able to determine which substances are harzardous and identify potential substitutes.

Choose materials for high-temperature environments
Article Abstract:
Selecting materials for high-temperature applications is not an easy decision to make, since the process environment and intended use, come into play. Problems may occur due to distortion and cracking caused by thermal expansion and contraction. For instance, a hight-temperature alloy could change 1/4 in/ft from ambient to 1,000 degrees c. The designer has to understand that the process environment will significantly influence the selection of the material at all stages of the task.
