Abstract :
The distillation process remains as the most common method of separation in chemical
process industries. The energy used from this process accounts for an estimated 3% of
the world energy consumption. The Dividing-Wall Column (DWC) for separation of
multi-component mixtures has recently become a major concern ofindustries. The design
of DWC is based on Thermally Coupled Distillation System (TCDS) eliminating some of
the operational equipment. This paper presents the results of simulation of a DWC by
using 3-simple sequence column model based on shortcut method by a commercial
chemical Engineering software for purification of 1,3 butadiene unit.
From the results, it is shown, by using a DWC instead of two conventional sequential
column, the heat duties of both the condenser and the reboiler are reduced about 28.5%
and also desirable purity of the key-components for the case of study have been achieved.
