Biomethane production in biogas plants
Matoušek, Jakub ; Miklas, Václav (referee) ; Vondra, Marek (advisor)
This bachelor thesis deals with the production of biomethane in biogas plants. The introductory part presents the operation of the biogas plant, its inputs, components, and products. The main part of the thesis deals with the perspective of biomethane in the Czech Republic and Europe and progressive technologies for the conversion of biogas to biomethane. The basic principle, advantages and disadvantages of each upgrade method are given. Common technologies at the level of commercial readiness include high pressure water scrubbing, organic physical scrubbing, chemical scrubbing process, pressure swing adsorption and membrane separation. The mentioned methods of biogas upgrading are evaluated and compared with regard to their practical applicability in the Czech environment.

Upgrading biogas by PSA
Krhut, Štěpán ; Havlásek, Martin (referee) ; Zejda, Vojtěch (advisor)
This work deals with bio gas cleaning by a PSA method and modernizing of a laboratory unit. Raw bio gas contains many unwanted elements like carbon dioxide mostly which lowers its energy potential then. To extend the possibilities of usage of bio gas it is necessary to remove such elements. One of the well-known method for eliminating CO2 out of the bio gas is the method called Pressure Swing Adsorption (PSA). This work describes PSA method and compares it with other methods for cleaning the bio gas. In the following part of my work I am introducing the original laboratory PSA unit which is placed in the laboratory of UPI institution for research purposes. The modernization of the method was made by changing the manual valves for electromagnetic ones and there was also designed a new control system unit for two control modes. For manual and for automatic. The essential function is based on remote controlling the valves either by switches or by a program. The electric control panel was created for such required modes. The automated process was controlled by Arduino programming platform which was integrated into the panel. In the case of the next measurement and reading there was created a detailed description for user on how to operate the control panel and also the comments for control program of automatization.
