GICON Biogas Process two-stage dry-wet fermentation with split hydrolysis High-performance fermenter with effective utilization of the reactor volume due to the GICON Process. Filling of a percolator with agricultural machinery 04 Process flow diagram of the GICON Biogas Process Simple solution - enormous impact The GICON Biogas process with most of its major process steps was developed at BTU Cottbus (Prof. Busch et. al.) in cooperation with GICON and has been patent-protected several times, including internationally (Patent DE 10 2204 053 615.5, additional patent applications for design details and process variations). It has been designed to operate in two steps, with a systematic separation of microbiological decomposition steps. During the first step (hydrolysis), organic components are eluted from the substrate matrix and converted into organic acids and other water-soluble decomposition products. This watery solution (hydrolysate), containing organics, is fed into the second step, the methanization, which is designed as a packed bed vessel. Due to the immobilization of methane-forming microorganisms on the surface of the packing material, large methaneforming potentials will be available at any given time. Thus, short residence times of the hydrolysate can be achieved, a solution which poses a unique option for the controlla-bility of the biogas production. The environmental conditions (temperature and pH, among others) are controlled and optimized separately in both process steps. By applying the innovative GICON biogas process, major disadvantages of conventional facilities are omitted. Since movement of the solid substrate does not occur during the operation, the system is robust with respect to possible impurities content. This is especially important for feedstocks such as biological wastes and landscaping-generated wastes. The use of the organic fraction of household waste is also possible and has already been successfully tested. Cleaning and maintenance of the percolation step can occur between substrate charging cycles without interruption of the biogas generation process. batch-wise addition and removal of feedstock multiple percolators in a garage setup percolation percolation stabile by-product appropriate, for example, for composting percolate = hydrolysate percolate return hydrolysate vessel -buffer storage- methane production control hydrolysate methane reactors return waste water, liquid fertilizer biogas 70-80% CH 4 packed bed aeration and polishing pool sludge liquid effluent
GICON Biogas Process a future-proof energy technology Efficient and stable The primary goal during the development of the GICON Process was the attainment of optimal process conditions for diverse groups of microorganisms in adherence with high process stability. Accordingly, a two-stage process with integrated solid separation and buffering of the liquids was implemented. The splitting off of CO 2 , which already occurs during the hydrolysis phase, can be separately discharged. The result is a methane content in biogas within the methane reactors 15-20% higher per volume than conventional plants. Flexible and controllable on demand Unprecedented in biogas technology is the controllability of biogas production. The foundation of this feature is first, the buffering of energy-rich hydrolysate in an intermediate storage tank, and second, the constant availability of the methane-forming bacteria (immobilized on a solid carrier substrate in the methane reactor). Due to a short residence time of the hydrolysate in the methane stage, a change in the rate of hydrolysate feeding promptly effects a change in the biogas production. Control of biogas production (depicted are results from investigations at BTU Cottbus, Department of Waste Management) Future-oriented energy generation should be safe, environmentally friendly, flexible, and its application cost-effective. GICON biogas plants meet these requirements in many ways. Almost all plant substrates can be utilized. Even small facilities can be operated in a safe and efficient manner. GICON Bioenergie GmbH’s extensive technological know-how in a wide spectrum is available to meet your biogas needs.
