چکیده مقاله:

The distillation process remains as the most common method ofseparation 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 ofDWC 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 of1,3 butadiene unit. From the results, it is shown, by using a DWC instead of two conventional sequential column, the heat duties ofboth the condenser and the reboiler are reduced about 28.5% and also desirable purity ofthe key-components for the case ofstudy have been achieved.

a study on thermodynamic models for simulation of 1,3 butadiene purification columns

attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...

Design and Analysis of Divided Wall Column

In this study, an efficient design method has been proposed for determining the optimal design structure of the dividing wall column. Preliminary design parameters are fixed on the basis of well-known shortcut method (Fenske-Underwood-Gilliland). The rigorous optimization is used to obtain the optimal design parameters of the divided wall column. Divided wall column has total eight design varia...

Modeling and simulation of a wetted-wall column for SO2 absorption with aqueous ammonia solution

In a wetted-wall column of pilot-scale sulphur dioxide removal efficiencies were measured at 20 and atmospheric pressure with aqueous ammonia solutions. The liquid-phase mass transfer coefficient and gas-phase mass transfer coefficients of the system were determined. Based on the classical two-film theory the mathematical model was built to describe the complex absorption process. Combined with...
