Process control of a distillery
Sejkora, Martin ; Kopečný, Lukáš (referee) ; Veselý, Libor (advisor)
This master‘s thesis deals with the design of a control system for a distillation column. It deals with the issue of distillate production and acquaints the reader with the necessary knowledge that is necessary to understand the purpose of the work. The practical part of the work presents a specific distillation column, the means for its control and the method of implementation of the control system, then the visualization of the control system and the method of control. Part of the work is the evaluation of the results and benefits of the work.

Batch control for model of distillation column
Vobejda, Lukáš ; Kacz, Peter (referee) ; Štohl, Radek (advisor)
This thesis deals with the batch controlling of a distillation column model. The thesis is divided into several parts. The first part, which is more theoretical, summarizes the description of the batch controlling, the distillation process and the equipment used, including the model of the distillation column itself. The second part is focused on the practical implementation. The beginning of this part displays different types of the models produced by the Standard 88. This section is followed by a description of a device database in the environment of FactoryTalk Batch Equipment Editor, creation of a logical phase codes using functions of the PhaseManager in the environment of RSLogix5000 and a creation of a recipe in the environment of FactoryTalk Batch Recipe Editor. The last part of this thesis deals with the visualization created in the FactoryTalk View Studio SE and final testing of the entire process.

Utilization of waste heat from rectification
Frank, Vojtěch ; Konečná, Eva (referee) ; Touš, Michal (advisor)
The purpose of the thesis is to draw up a model of the energy and material balance using technical and technological analysis of the current state of production of waste heat in the process of distillation. Using these results, subsequently evaluate the energy potential of individual streams and propose optimal energy savings using waste heat. Emphasis is placed on the modelling of the process and the various proposed savings options. The result is also an evaluation of the potential of the proposed savings based on the results of the calculation.

Seawater desalination
Kamenický, Robin ; Hájek, Zdeněk (referee) ; Maar, Tomáš (advisor)
Každodenní nedostatek pitné vody vede ke snahám tento problém řešit. Jedna z možnosti je odsolování ať už destilační, za pomoci membrán a osmózy, či dalších nekonvenčních způsobů jako je zmražení vody. Tato práce se zabývá možnostmi odsolování. Popisuje způsoby destilační, reverzní osmózu, solární odsolování a nezapomíná ani na separaci pitné vody pomoci zmražení. Spolu se získáváním pitné vody ze slané nastává také otázka energetických zdrojů. Využití fosilních paliv, obnovitelných zdrojů energie a jaderné energie, je tedy další nepostradatelné téma popisované v této práci. V neposlední řadě se zde také můžete dočíst o možném dopadu odsolování na životní prostředí, ať už z hlediska globálního v podobě možné produkce skleníkových plynů nebo dopadů lokálních. V závěrečné kapitole je podrobná ekonomická analýza odsolovacího zařízení pomoci počítačového programu DEEP. Popisované zařízení je na bázi multi effect distillation a reverzní osmózy, pro které se získává energie z jaderné elektrárny.

Automatic table distillation column
Ružička, Michal ; Hanák, Pavel (referee) ; Dejdar, Petr (advisor)
The semester thesis deals with the issue of alcohol distillation and analysis for understanding at the level for construction of the facility itself. It deals with the requirements for the distillation equipment and parameters that may affect the quality of the distillate. On the basis of which is created automated control by microcontroller. This apparatus is exposed to tests and measurements of the required values during distillation. The cooling unit was also built and measured.

Design of column
Marko, Libor ; Buzík, Jiří (referee) ; Nováček, Filip (advisor)
The thesis contains information about the design of pressure vessels and describes their individual parts. It is mentioned production of individual parts and the process including assembly parts in one unit. The thesis includes options of control and testing of pressure vessels. It is described kinds of built-ins of distillation column and the basic principles and types of distillation. It is created stress analysis of pressure vessels parts according to ČSN EN 13 445 – 3, and also stress analysis of the selected part of column by using FEM. Mechanical drawing of distillation column is part of the thesis.

Control system for laboratory distillation column model
Chlad, Petr ; Šír, Michal (referee) ; Štohl, Radek (advisor)
The aim of this master’s thesis was to create a control system for laboratory distillation column model. There are two different models considered. Real and software model. For the real model suitable components were selected and the model was built. Software model allows safe testing of control algorithm functionality without the need of real model. The simple visualization that works with both models was developed. Both distillation column models - real and software - were tested as a last phase of work.

Influence of the temperature on the preparing of asphalt mixtures with higher amount of RAP
Škrobáček, Petr ; Koudelka, Tomáš (referee) ; Varaus, Michal (advisor)
This bachelor thesis is focused on the preparation of the reclaimed asphalt pavement for production of asphalt mixtures. In the thesis there is investigated the effect of the temperature of preparation the reclaimed asphalt pavement on the characteristic of the bitumen content. In the theoretical part there is described bitumen as such and reclaimed asphalt pavement. In the practical part there is described the preparation of the material for laboratory tests. The next step is the extraction and distillation of bitumen. These bitumens are tested according to depredescribed tests: ‘Determination of needle penetration (ČSN EN 1426)’, ‘The softening point (ČSN EN 1427)’ and ‘Dynamic shear rheometer’. In the last section of this bachelor thesis there is a comparison of the individual properties of the rendered bitumen of the asphalt mixtures of reclaimed asphalt pavement, with the aim of evaluating temperatures of preheating and degradation of the bitumen on the final characteristic of the asphalt mixtures witch higher quantity reclaimed asphalt pavement. The measured values of the temperature for preparation of reclaimed asphalt pavement shows that the temperature of the asphalt mixture before production has a significant effect on the characteristics of the bitumen, which is included in the reclaimed asphalt pavement. There is evident the difference between specimen of the asphalt mixture of reclaimed asphalt pavement and the reclaimed asphalt pavement. It is visible only from the bottom layer too.
