A CONTROL SYSTEM FOR METHANATION REACTOR

The invention regards a system for controlling a biomethanation reactor comprising a biomethanation reactor comprising a first fluid inlet and a first fluid outlet, wherein the biomethanation reactor is configured for at least one first fluid flow between the first fluid inlet and the first fluid outlet defining a first direction of the at least one first fluid flow; a first gas concentration sensor configured to measure a first gas concentration at a first gas concentration sensor location within the biomethanation reactor, and/or at least a first temperature sensor and a second temperature sensor configured to measure a first temperature at a first temperature sensor location within the biomethanation reactor and a second temperature at a second temperature sensor location within the biomethanation reactor; respectively, and at least one controller configured to regulate the at least one first fluid flow into the biomethanation reactor based on the first gas concentration or on the first and second temperatures. A method for controlling a biomethanation reactor is also disclosed.
