Pinch design process changes

In the new revamp study (Alanis and Sinclair, 2002), a pinch analysis study considering both process changes and heat integration was conducted to identify process design changes that can reduce refrigerant compressor shaftwork. Pinch and... [Pg.478]

FEHE Model There are no phase changes or small pinch temperatures in the heat exchanger. Therefore a 10-lump model is used for this unit. The steady-state exit temperatures predicted by the lumped model are close to those calculated by the rigorous countercurrent model used in the steady-state design. Table 7.2 compares the steady-state conditions for the process obtained from the dynamic model with those obtained in the steady-state design. [Pg.381]
