Procedures for the commissioning of methane-containing gas-producing or leading facilities, in particular biogas plants or pipelines

摘要

In a start-up process for an assembly which generates gases containing methane e.g. biogas generators, oxygen within the assembly is especially first expelled by introduction of methane into the assembly. In a start-up process for an assembly which generates gases containing methane e.g. biogas generators, oxygen within the assembly is especially first expelled by introduction of methane into the assembly. The expulsion continues until the oxygen content in the expelled gas mixture falls below six per cent by volume. In the start-up process, the reactor outlet gas valves are closed to associated methane storage or processing assemblies. A reactor gas bleed valve is opened in the upper part of the reactor and the reactor is then pre-heated by filling with warm water, followed by inoculation with a starter culture of biogas-generating micro-organisms, followed by introduction of the organic ingredients. The gas bleed is monitored until the oxygen content falls to six preferably four percent, following which the gas bleed valve is closed and the valves opened to the associated methane storage or processing assemblies.
