متن کاملThree-component Distillation Columns Sequencing: Including Configurations with Divided-wall Columns
In the present work, the exergy analysis and economic study of 3 different samples of threecomponent mixtures have been investigated (ESI>1, ESI≈1, and ESI<1). The feed mixture has been tested under three different compositions (low, equal, and high contents of the intermediate component). A quantitative comparison between simple and complex configurations, considering thermally coupled, thermo...
متن کاملDistillation Startup of Fully Thermally Coupled Distillation Columns: Theoretical Examinations
The fully thermally coupled distillation column offers an alternative to conventional distillation towers, with the possibility of savings in both energy and capital costs. This innovative and promising alternative provides the opportunity to separate a multicomponent mixture into fractions with high purities merely in one column. A lack of knowledge still exists when dealing with the startup o...
متن کاملAnalysis and Control of Distillation Columns
Here MI is the total holdup inside the column, and MD and MB are the condenser and reboiler holdups. S = yD(1 xB) (1 yD)xB is the separation factor and Is = DyD(1 yD) + BxB(1 xB) is the \impurity sum". Note that Is may be extremely small for columns with both products of high purity (1 yD and xB both small) resulting in very large linearized values of 1. The response to changes in the internal ...
متن کاملShortcut Design of Extractive Distillation Columns
Extractive distillation is a common process for the separation of homogeneous azeotropic mixtures. In this process entrainer feed flowrate and reflux ratio of the extractive column represent the crucial design degrees of freedom which govern feasibility and operating cost. In this work feasibility and operational stability of the extractive column is related to the analysis of the nonlinear dyn...
