Abstract

In Shipboard applications the height of a distillation column is particularly important, as shorter columns should be less susceptible to ship motions; forces other than gravity, due to column motion, can cause liquid maldistribution leading to reduced column stage efficiency. Therefore, when considering the design of a shipboard ASU, factors other than power and capital cost come into play, which may affect optimisation of the plant design.
