separation process engineering course

Which one of the following answers is incorrect? a. The CP-rules of PDM (Pinch Design Method) ensure that the temperature profiles of exchangers at the pinch diverge away from the pinch. b. Stream splitting criterion for a HEN design depends ONLY on stream number and CP criteria. Oc. In section below the pinch, the composite hot gives heat to composite cold with only residual cooling required. Od. There exists a correlation between AT min and utility usages. Oe. The Pinch Design Method (PDM) requires CPH2CPC (for cold end design) and CPHSCPC (for hot end design) for avoiding ATmin violation, in all stream matches. CLEAR MY CHOICE
