Distillation pinch points and more

Rising energy costs have spawned renewed interest in improving methodologies for the synthesis, design and/or retrofitting of separation rocesses. It is well known that energy use in many process industries is dominated by separation tasks—particularly distillation. In this work, the hortest stripping line approach recently proposed by Lucia, Amale, & Taylor (2006) is used to find minimum energy requirements in distillation. he new aspects of this work show that this shortest stripping line approach can find minimum energy requirements for
