Biogas plants

Biogas plants are among the renewable sources of energy and have their firm place in the modern 21st century energy. They provide a stable supply of electricity and heat, without burdening the environment with emissions, long-term policies are supported by the European Union. These projects contribute to the protection of the environment, not only in its contribution to reducing greenhouse gas emissions but also waste from agricultural production or biodegradable municipal waste. Thanks to State aid in the form of investment subsidies or feed-in tariffs are also beneficial economic investment. 

How it works

The technology is based on a controlled anaerobic fermentation process where organic substances are converted to energy-rich biogas through heating and stirring. Biogas is captured in the gas tank, cleaned and then burned in a cogeneration unit. Utilized substrates in form of digestate and fugate have different further utilization, most often exported to the field as fertilizer, but can also be further processed for energy. Substrates for the operation of the biogas plant can be e.g. corn silage, manure, grass silage, sugar beet cuttings, distillers soluble, biodegradable municipal waste etc.

Technology

The biogas plant consists of several technological components; the main ones include input tank and feeding system for solid substrates, fermenter, postfermenter, end store tank, gas holder, technical building and more. The components are interconnected by piping to distribute substrates and biogas. An important part of the station is cogeneration unit to produce electricity and heat, trafostation and interconnection of biogas plant and distribution system network 22 kV.

 

 

 

The main advantages of our technology solutions

  • Highly efficient vertical paddle lowrun mixers creating optimal conditions for the production of biogas
  • Targeted stratification inside fermenter and thus the optimal conditions for individual strains of micro organisms, which guarantee the stable operation of the process - high biogas yield
  • Possibility to work at 15% solids in the fermenter and eliminate the need for the use of dilution water input (which also brings significant savings in logistical costs in removing digestate)
  • Guaranteed elimination of floating layer thanks to substantial coverage of mixed volume even below the surface
  • Low power consumption of the whole technology
  • Possibility to service agitators in the fermenter during full level state
  • Thanks to the two-Tank concept - low demand for building space
  • Efficient distribution of technological components to minimize the built up area and shorten the technological connections
