Analysis of distillation unit by using the meihod of flickernoise spectroscopy
(2015) Novakovska, Natalia; Kyshenko, Vasil
To establish the fundamental changes in the behavior of the distillation process, to prevent the occurrence of critical situations the proposed method of flicker-noise spectroscopy. The parameters of the method by studying the specific conditions of the object on the time-series operation bragorektifikatsionnry installation distillery.
Fractal analysis of distillation unit time series in prediction and control problems
(2016) Novakovska, Natalia; Kyshenko, Vasil
The behavior of distillation unit as a control object is characterized by stochasticand chaotic manifestations. This requires their identification by the nonlineardynamics methods for organizing the specific respective control strategies. Weused the synergetic methods and the theory of deterministic chaos for solving problems of distillation unit prediction and control. Time series analysis wasconducted using the Rescaled Range algorithm of the analysis of Hurst, the coatingmethod and the correlation methods. Time series are processed using the software package FRACTAN.
Intelligent system of technological monitoring of distillation unit
(2015) Novakovska, Natalia; Kyshenko, Vasil
Розглянута структура і визначені задачі інтелектуальної системи технологічного моніторингу процесів ректифікації. The structure and tasks defined intellectual systems of technological monitoring of rectification.
The main causes of the flooding column process of distiller
(2014) Novakovska, Natalia; Kyshenko, Vasil
The process of flooding is not calculated regime of column operation. The column can be no more than two or three minutes in this state. During this period reflux firstly fills the inner cavity of the column, then fills the distillation tube, and then accidentally releases from the column through the upper nipple of distillation tube - the tube of connection with the atmosphere. The process of column flooding is easy to hear as a specific «gurgling» noise in the column.
