The document outlines different approaches to reactor design flowsheets from ideal to realistic. It starts with an ideal reactor design flowsheet that considers only chemical and physical data and mathematical models. It then shows a more traditional design that incorporates laboratory, bench, and plant scale tests from semiworks to pilot plants. Finally, it presents a realistic design flowsheet that compares models to actual performance and modifies models based on physical plant data.
