Özet

In small farms in which biogas consumption is not continual, there occurs problem with the storage of the produced biogas. Because of its nature, biogas cannot be stored in middle or high pressure without purification. For this reason, floating dome type or balloon type low pressure gas storage systems are used. The reason why biogas systems are not common in the rural area is that floating dome gas storage systems have movable parts and that the materials used in balloon type systems are not durable and safe. In this study, performance tests were executed by preparing a safe system having no movable parts and easy to use. The gasometer in question provides the operating pressure that the devices need in order to operate without the help of another pressurizer by the principle of transposition of water. The acquired pressure values of 20-30 kPa enable biogas to be carried more than 100 m away with low costs. Maintenance cost is low because it does not have movable parts. It is safer against pressure increase because it is open to the atmosphere. Furthermore, because CO2 and H2S dissolve more than CH4 in water it was seen that the said gasometer could be used to purification biogas. In the tests 25-30 % CO2 removal and 98-100 % H2S removal was observed. This gasometer called "Gasometer with the function of gas purification for biogas facilities" numbered "TR 2006" was taken under protection and the simplicity, the functionality and safety increase the possibility of its usage in biogas systems in the rural area.
