Abstract
A method for the optimisation of the gas injection system and for the control of biogas production processes including a step of detecting a working parameter of the biogas production process and a step of driving the biogas production process based on real-time processing of the working parameter.
Claims16
Method for the optimisation and control of biogas production processes comprising the steps of:
- providing a digester (100) comprising a containment body (1) internally defining a containment volume (V) intended to contain sludge and biogas;
- filling the containment volume (V) with sludge;
- providing a recirculation element (3);
- installing the recirculation element (3) so that said recirculation element (3) is in fluid communication with said containment volume (V) and said compressor (2);
- sucking from the containment volume (V) a part of the biogas produced and/or contained in the sludge;
- feeding at least part of the sucked biogas into the recirculation element (3);
- injecting, in a sequential logic, said part of the sucked biogas within the containment volume (V) through respective injection portions (I) of the recirculation element (3);
- detecting at least one working parameter of the digester (100) by means of at least one detector device (5);
- transmitting the working parameter to a control unit (200);
- processing the working parameter by means of the control unit (200);
- driving by means of the control unit (200) the activation of one or more injection portions (I) based on said processed working parameter.
(200) is operatively connected to injection valves (4) to drive a sequence of successive movements of respective injection valves (4) between the opening configuration and the closing configuration.
