ideal reactor. The functions E(t) and F(t) will be developed for ideal PPRs, CSTRs and laminar flow reactors. Examples are given for diagnosing prob-lems with real reactors by comparing t m and E(t) with ideal reactors. We will then use these ideal curves to help diagnose and troubleshoot bypassing and dead volume in real reactors.
