be changed to a less severe one that provides an economic advantage.

A list of possible justifications for using temperature and pressure conditions outside the ranges given
above are identified in Tables 6.1 through 6.3. The material provided in Tables 6.1 to 6.3 is based upon
elementary concepts presented in undergraduate texts covering thermodynamics and reactor design.

Table 6.1 Possible Reasons for Operating Reactors and Separators Outside the Temperature
Ranges of Special Concern

We describe below the rationale used to justify operating at temperatures that are of special concern
presented in Table 6.1. The justification for entries in Tables 6.2 and 6.3 has a similar rationale.
