Advanced models for cryogenic distillation columns
2014 IEEE International Conference on Automation, Quality and Testing, Robotics, 2014Cryogenic air separation plants are widely used in industry but are energy consuming processes. The operating costs justify the need for an efficient control of the distillation process. Dynamic models of separation columns are complex and of high order making their use in control design practically impossible.

Robust Control of Benzene Distillation Column
2019 22nd International Conference on Control Systems and Computer Science (CSCS), 2019In the paper are presented the authors' research on the design of a robust control system for the quality of benzene obtained by a distillation process. Initially, the distillation column control structure is presented, followed by the analysis of existing automation systems.

Industrial comunication in distillation column model
IFAC Proceedings Volumes, 2012This paper introduces the model of distillation column for the steam distillation. After the introduction of a steam distillation process, the model description and list of actuators and sensors is mentioned and described. In the last chapter brief overview of model control is shown.

Robust Analysis of Distillation Column Dynamics
IFAC Proceedings Volumes, 1995Abstract The robust stability and performance of a binary distillation column model is analysed using a minimal state space representation. The uncertainty modelling of the column is resulted in an LFT form with a four element diagonal block structure taking into account the dependence between the steady state gains.

Modelling and dynamics of an extractive distillation column
The Canadian Journal of Chemical Engineering, 1983Much of the published research literature on distillation column dynamics and control has been focussed on binary systems or on multicomponent systems in which key components are used to define the operations. This paper presents both non-linear mass and energy balance models and experimental results for an extractive distillation system separating ...

Distillation columns are unit operations that are very common in chemical, petrochemical and even sometimes in metallurgical industries. Moreover, they consume a large part of a plant’s total energy. Consequently, their close control is very important. The model of a typical distillation column is detailed. Different control strategies are explained by

Robust algorithm for control of distillation column
2017 4th International Conference on Control, Decision and Information Technologies (CoDIT), 2017The paper describes the robust algorithm for distillation column under parametric uncertainties of column parameters and external disturbances in feed. The proposed control system uses the auxiliary loop algorithm which allows us to get effective controller. The proposed algorithm guarantees the compensation of perturbations with the required accuracy.
