Abstract

A new generalized algorithm for design calculation of various kinds of complex distillation columns(with multiple feeds

vapor and liquid phase side withdrawals and intermediate heat exchangers) has been developed. Based on specified independent variables: conditions of feeds

yields of light and heavy key components

yield and concentration of specified component in side-cut product

etc.

a set of optimum design variables (reflux ratio

number of equilibrium stages required

feeds and sidewithdrawals locations

etc. )were determined by optimization technique. This new algorithm as coupled with the SHBWR or PR model for vapor-liquid equilibrium and enthalpy calculations

has been tested on five-light hydrocarbon complex distillation columns(including three field operating columns)

with quite satisfactory results.
