Modular Biogas Facility, Method For Operating A Modular Biogas Facility And System For Monitoring And Control

A method for operating a modular biogas plant which comprises at least a plurality of tanks for receiving biomass, wherein at least two of the tanks are hydrolysis tanks and at least one tank is a fermenter tank and at least one gas storage for the biogas generated in the modular biogas plant, comprising the following steps:

• batch-wise filling of the hydrolysis tanks with biomass, wherein a first temperature range and a first pH range are predominating in the hydrolysis tanks;
• transferring the biomass from the at least one hydrolysis tank to the at least one fermenter tank by means of a pump;
• producing in the at least one fermenter tank biogas from the biomass, transferred from the at least one hydrolysis tank to the at least one fermenter tank, wherein the formation takes place at a second temperature range and a second pH range in the at least one fermenter tank;
• and
• monitoring continuously a production rate of the biogas and if the production rate of the biogas in the at least one of the fermenter tanks falls below a predefined value, biomass is supplied from one of the hydrolysis tanks until the production rate is again above the predefined value.

A system for computer-aided, centralized monitoring and control comprising:

• several modular biogas plants, wherein each modular biogas plant has at least two hydrolysis tanks, at least one fermenter tank, at least one pressure less gas storage tank and several housings;
• at least one data acquisition unit is assigned to several individual and movable modules of each of the modular biogas plants and each of the modules has at least one actuator and/or at least one sensor and/or at least one measuring point, which are communicatively connected to the least one data acquisition unit;
• a communication device which is assigned to each of the modular biogas plants and delivers data from the data acquisition unit to a cloud or receives data from the cloud;
• a central control and monitoring unit which is communicatively connected to the cloud in order to monitor the modular biogas plants in a centralized manner and to control them automatically;
• and
• a user interface is assigned to each of the modular biogas plants to which messages or warnings can be transmitted from the central control and monitoring unit.
