Blackbox with PLC and demonstration task
Frýdl, Lukáš ; Kacz, Peter (referee) ; Štohl, Radek (advisor)
The goal of this bachelor’s thesis was to create a simulation including visualization of a distillation column, with the primary aim to the thermal processes of simple distillation and of distillation with a water stream. Visualization is displayed on the HMI panel, which is placed on the front doors of the switchboard. The switchboard is designed as a blackbox, which means that the knowledge of the inside functionality is unnecessary for the user to work with the device. Both software and hardware test were performed. The functionality of the software was tested using a mixture of water and acetone. On the hardware side tests of inputs and outputs were done.

Characterization of intermediates and waste products of some fermentation productions
Kilian, David ; Skoumalová, Petra (referee) ; Márová, Ivana (advisor)
This bachcelor thesis was aimed on characterisation of intermediate and waste products of some fermentation productions. The theoretical part of this thesis is aiming on characterization of raw material and its fermentation, process of distillation, waste product and introduction of main active components of all these intermediates. In the experimental part were characterized intermediates and products regarding the contents of sugar, ethanol and polyphenol. All these extracts contain particular levels of polyphenol and sugar corresponding to individual phases of fruit distillates production. The chemical characteristics of extracts from different phases of fruit distillates production were compared. Parameters as total phenolics, flavonoids, glucose, fructose and ethanol were evaluated. Subsequently the changes between individual phases were described. In conclusion, a solution of further use of waste products formed during fruit fermentation process was suggested.

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.

Obsah přiboudliny v ovocných destilátech
Borko, Jozef
Fusel typical compounds for fruit juices, but also for distillate fractions (Luther head, heart, tail). Of the varieties TOPAZ was ready to leaven, which was converted by distillation to the mentioned distillate fractions. Samples of fresh apple juice and distillate stocks were stored in a cooling box at - 18 ° C. Analysis of fusel oils and other ingredients of fabric were determined SPME / GC / MS. Analytical treated sample (captured in the hollow fiber), followed by desorption of the liquid was divided column. The mass spectrometer analytical peaks quantified according to the standard for which is a recognized m / z. Of the amount of the analyte for each analytical unit (juice - boiling fraction) were separated substance of analytical chemical group of the alcohols, branched alcohols, aldehydes, ketones, esters and terpenes.

Destiláty z hroznů a vín
Šimšová, Hana
Thesis titled Distillates from Grapes and Wines has been developed at the Institute of Postharvest Technology at the Faculty of Horticulture at the Mendel University in Brno in the years 2015-2016. The aim of the work was to focus on a range of spirits from grapes and wines in selected parts of the retail network. The work discusses the technology of production of spirits from grapes and wines, quality parameters and statutory limitations in their manufacture. It provides an overview of the spirits from grapes and wines offered in retail shops Tesco, Albert and beverage wholesaler Dios Brno.

Obsah silic ve vybraných druzích léčivých, aromatických a kořeninových rostlin, které se používají i jako „zelené koření“
Kyselová, Martina
Ethereal oils are described in this bachelor's work. There is a characterization of ethereal oils, of its occurrence, properties and way of isolation these plants. The best-known types of these plants, which are called "green spice", are eleborated in this work. It also contains experimental determination of content by choosen samples, which were acquire from two sources - LEROS s.r.o company and from Žabčice, MENDELU in Brno. Ethereal oils were insulated by a method of destilation with water vapour. Acquired plenty of e.oils was compared with a norm's requirements, eventually with a czech formulary.

Wireless communication between remote PLC and lab model
Maléř, Martin ; Šír, Michal (referee) ; Štohl, Radek (advisor)
The main aim of this bachelor’s thesis was to establish wireless communication between programmable logic controller (PLC) used in laboratory model of a distillation column and PLC, which controls the technological process. Industry bus ModBus TCP/IP and wireless modules in client-server mod was chosen to reach this goal. To control the technological process was created visualization. At the finish of the work everything was tested.

Research of Equipment for Sea Water Treatment and Other Applications
Hájek, Zdeněk ; Klemeš,, Jiří (referee) ; Odstrčil, Miloslav (referee) ; Jegla, Zdeněk (advisor)
As water resources are rapidly being exhausted, more and more interest is focused on the desalination of sea water and brackish water. Increasing amounts of fresh water will be required in the future due to the rise in population rates, increasing living standards and the expansion of industrial and agricultural activities. The thesis is concentrated on current issues of treatment of sea water, mainly the desalination based on the distillation principle, in order to develop a unit for seawater treatment. The aim is to develop a compact modular unit for seawater desalinate on based on the implementation and evaluation of experimental tests on the experimental unit. The solution includes an overview of systems for treatment of seawater, a discussion of structural and material aspects of the units, design and manufacture of the experimental unit and confrontation the calculated values with the results of experimental measurements.

Vacuum evaporation efficiency improvement
Havlásek, Martin ; Máša, Vítězslav (referee) ; Vondra, Marek (advisor)
This thesis is focused on experimental work in the domain of vacuum evaporation efficiency improvement. The first part introduces theory of liquids evaporation and its influencing factors, then multi-stage flash distillation technology. The next part of theory is an overview of other technologies used for desalination of sea water and introduction to the design of experiments. In the practical part are selected factors affecting efficiency of device and experiment plan is designed for them. When the experiment is done, optimal operating conditions of technology are designed on basis of analysis.
