Usability of stillage from ethanol production
Audy, Dan ; Večeř, Marek (referee) ; Leštinský, Pavel (advisor)
This work solves the use of stillage from ethanol production. Also solves processing into material DDGS and then solves the material and energy balance. This material and energy balance was calculated for 7070 kg of stillage per hour. The final energy requirements of the process were based on the amount of stillage produced to obtain 1 m3 of ethanol. The results of this work offer an insight to the problems of processing stillage. Thanks to conversion for 1 m3 of produced ethanol, results is also offerring the possibility of fast conversion of an approximate energy needed for devices of other capacities.

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.

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.

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.

Energy consumption of equipressure and various pressures technical alcohol distillation
Audy, Dan ; Leštinský, Pavel (referee) ; Smejkal, Quido (advisor)
This hork compares the heat consumption of two units for the production of technical alcohol. The aim is to compare ordinary arrangement of rectifying distillery with an alternative arrangement, based on a modified pressure device profile. The first unit is based on the classic arrangement brewhouse, working at atmospheric pressure. The alternative unit works with different pressures in columns. In this case, the pressures are chosen so that it was possible to use heat from the head of overpressure rectification column for reboiler of vacuum mash column. The principle of pressure differences between the two columns and appropriate choice for this difference also allows the beneficial use of surplus heat. It also reduces the risk of clinkering incrusts in reboiler mash column because this works at lower temperatures than the mash column atmospheric embodiment. The comparisons of the media in this work are: The amount of steam used for reboilers of both columns, the amount of cooling water used for condensation and cooling of process streams. Furthermore, an approximate estimate of electricity consumption for pumps and other machinery. For both units is considered the same amount of mash and the same amount of product of comparable quality. The product was a technical alcohol 96.4% aa at a temperature of 25 ° C.

Industrial production of ethanol
Flajs, Roman ; Zichová, Miroslava (referee) ; Omelková, Jiřina (advisor)
This bachelor thesis deals with ethanol production for food and car industry. The aim of this work is to give a summary of different kinds of raw material especially lignocelluloses and microorganisms used for its processing and fermentation. The thesis focuses especially on technological process of ethanol production and the utilization of different materials for fuel production.

Calculation of column destillation unit.
Bytešník, Jan ; Jecha, David (referee) ; Jícha, Jaroslav (advisor)
The bachelor's thesis is divided into three main parts. The first part discusses principles and theoretical base of the distillation process. The majority part of this thesis includes solution of elementar steps towards the resultant parameters of the distillation column. This results may be served like input parameters during other calculations, which can make an effective optimalization of the distillation column for the practical use. The last part of bachelor's thesis compares results of the second part with results, which was generated by ChemCAD aplication with the same input numerical values.

Raw materials and microorganisms to distilled beverage production
Jechová, Iva ; Vitoulová, Eva (referee) ; Babák, Libor (advisor)
The production of distilled ranks among established fermentative production. Than the first – quality spirits is became from raw material, it is obliged to change ranks processes. The important from the processes are alcoholic fermentation, which proceeds owing to mikrobiological cultures, distillation and subsequent rectification and at not least ranks aging distilled, for which is necessary selected appropriate container. For all processes the granted conditions are appointed, under which the processes would ocur, so resulting distilled achieved the first – quality and the best sensory character. Therefore this work does one’s best map these single processes and it is largely intent on fermentative processes.

Design of technological set of device for production of bioethanol with a yearly capacity up to 500 000 litres.
SLANINKA, Milan
This bachelor thesis deals with the production of bioethanol for the use as fuel. The first theoretical part describes the process of the bioethanol production from the commonly grown cereals, then it focuses on the sources and characteristics of materials that can be used for the bioethanol production, it also follows the legal burden put on such production. The other part of the thesis contains the design of the technological set of devices for the bioethanol production with a given capacity of the yearly production.
