Designing a Divided Wall Column

Two of the most important tasks facing refineries today are to increase conversion depth and to increase energy efficiency. To achieve deep conversion, refineries have started to invest in heavy residue processing. Increased energy efficiency is achieved by better utilisation of all energy sources and by increasing heat recovery in refinery processes. Distillation is the most common and important physical separation method. Therefore it is not surprising that attention is dedicated to increasing energy efficiency in this process. Distillation is also a process that is responsible for a large percentage of the world’s energy consumption. Due to its significant energy inefficiencies, some call it the ‘energy dark horse’. It is known that distillation represents about 95% of all separations in the chemical industry and that, in the US alone, about 40 000 distillation columns exist in all industries.
