ABSTRACT
This and the next chapter present methods that help one create a comprehensive list of design options. This chapter explains a process for developing flow sheets that reduce the tendency to converge rapidly, thus keeping open possible options. It involves focusing on technical functions before considering specific unit operations or equipment. Chapter 9 describes tools that will stimulate one’s thinking about possible options. Good list creation involves considering all the options before selecting one. Thus, before selecting an option, one must answer questions like:
• What are all the different unit operations that might be used for a technical function?
