Tips to Scale-up & Design

Chemical Engineering knowledge is necessary for scale-up consideration, process design, trouble shooting etc. Although the knowledge taught at the universities is important as foundation, we need more experience to address these areas in the practical situations.
PreFEED has obtained and is developing the practical knowledge by working with process industries. We would like to share some of our experience for you to use as tips.
