Abstract
The short-cut models for the atmospheric distillation column are extended to account for pressure drop in heat-integrated crude oil vacuum distillation columns. A model is developed for the vacuum steam ejector to calculate the steam requirements as a function of suction pressure at the top of vacuum column. These models for the distillation columns and the heat exchanger network are applied with in a non-linear optimization framework. The feed preheat temperatures, stripping steam flow rates, reflux ratio, and temperature drops are optimized to minimize the total annualized cost of the crude oil distillation system. This optimization framework can be used to achieve increased profits, reducing greenhouse gases emission , and throughput increase.
