There are typical ranges for process temperatures and pressures.
There should be a reason for operating outside these ranges.
In previous chapters, process flow diagrams (PFDs) were accepted without evaluating the technical features of the process. The process topology and process operating conditions were provided but were not examined. Economic evaluations may be carried out, but without confirming that the process would operate as indicated by the flow diagram.
