Abstract
Rate-based calculations theoretically offer more rigor and reliability for assessing column performance than the traditional equilibrium-stage approach. Unfortunately the rate-based method is ultimately tied to equipment performance correlations with limited predictive capability. We have undertaken an effort to develop significantly improved correlating expressions for mass transfer in columns containing sheet metal structured packings. To accomplish this, we have collected and simultaneously analyzed HETP data from 443 distillation experiments (Bennett, et al., 1992; Bravo, et al., 1985; Fitz, et at., 1999; Gualito, et al., 1997; and others) and 410 mass transfer area experiments (Tsai, 2010). The correlating expressions for the mass transfer performance for these sheet metal structured packings are shown below: (Equation presented).
