The efficient operation of a chemical process engineering system depends on several key factors. Chief among these are the proper selection of materials, the proper design of the process equipment and the proper selection of operating conditions. Poor selection of materials can result in process failure, increased costs and safety risks.

An inadequate design may lead to inefficient use of resources and increased downtime. Operating conditions that are either too hot or too cold can impact the reaction rate and produce undesired products. The ideal chemical process engineer must be knowledgeable in all these areas to ensure that the process is optimized for maximum efficiency and safety.
