New Method for Designing Distillation Columns of Multicomponent Mixtures
This paper presents a series of calculation procedures for computer design of ternary distillation columns overcoming the iterative equilibrium calculations necessary in these kind of problems and, thus, reducing the calculation time. The proposed procedures include interpolation and intersection methods to solve the equilibrium equations and the mass and energy balances. The calculation progra...
متن کاملA simple design method for multicomponent distillation columns
Multicomponent-distillation calculation methods are classified as rating or design methods. A few rating methods are widely used but none of the design methods has found general acceptance. Recently, a few design methods have been proposed using the stage-tostage calculations and starting from one of the ends of the column, but they require tedious calculations. We present here a simple design ...
متن کاملEconomic Optimization of the Reflux Ratio of Two Components Stage Distillation Columns
Distillation columns are complex processes for modeling and controlling. These columns are significant parts of most chemical industries for separation of components. Control of this process is essential for achieving certain purity for products with a minimum cost. However, nonlinearities, multivariable interaction, non-stationary behavior and severity of disturbances inside the column made th...
متن کاملState Estimator Design for Multicomponent Batch Distillation Columns
I n the control of batch distillation columns, one of the problems is the difficulty in monitoring the compositions. This problem can be handled by estimating the compositions from readily available online temperature measurements using a state estimator. In this study, a state estimator that infers the product composition in a multicomponent batch distillation column (MBDC) from the temperatur...
متن کاملModified method to improve the design of Petlyuk distillation columns
BACKGROUND A response surface analysis was performed to study the effect of the composition and feeding thermal conditions of ternary mixtures on the number of theoretical stages and the energy consumption of Petlyuk columns. A modification of the pre-design algorithm was necessary for this purpose. RESULTS The modified algorithm provided feasible results in 100% of the studied cases, compare...
