Design of a cryogenic exchanger for process gas liquefaction
Wittek, David ; Kudela, Libor (referee) ; Toman, Filip (advisor)
The energy density of liquid natural gas is more than five hundred times higher than in state of gas. A key component for its preparation is the heat exchanger, where the liquefaction takes place. The aim of this work is design of a condenser. Its implementation is like Giaque-Hampson type exchanger with a bundle of helical wound tubes. Technical solution for the device is proposend and various configuration of heat-carryig media placement are compared. Concepts with condensation inside the tubes and in the shell are studied. In addition to ensuring safe operation within the design conditions, there are fucused on minimizing the size of the equipment and the associated production costs.

Technology for liquefaction natural gas and its use and distributing
Konopiský, Karel ; Šnajdárek, Ladislav (referee) ; Škorpík, Jiří (advisor)
This bachelor thesis is concerned with technologies of liquefaction of gases, and methods of their subsequent storage and utilization. Firstly, I summarise a history of the technology of liquefying gases and reaching low temperatures. In the following parts, the thesis is focused on means of utilization and distribution of liquefied gases. Special attention is paid to liquid natural gas, which is the most used liquefied gas in practice. A separate part of the thesis is then designated to a method of liquefaction of natural gas.

Technology for liquefaction gases and its use and distributing
Štěpánek, Jindřich ; Kracík, Petr (referee) ; Škorpík, Jiří (advisor)
This thesis deals with technologies for gas liquefaction and storage. The first section summarizes the development of liquefaction technology using expanders and throttling valves, followed by current technology. This is especially a rotary expanders. The storage technology is the above-ground storage of cryogenic tanks. The thesis includes proposals turbine wheels for liquefaction lines and included two proposals liquefaction cycles.
