The hybrid energy production system and ethanol production from biomass

Wizualizacja Piaszczyna

Implementation:

The system is being implemented in two locations:

  • Piaszczyna, Miastko municipality, Bytów district, Pomerania Voivodeship.
  • In 2012 the investment was achieved funding from the Innovative Economy Operational Programme "Pilot project-Support for the first implementation of the invention" - We currently (February 2013) develop the technology and construction documentation.

  • Leszkowice, Pęcław municipality, Głogowski district, Silesian Voivodeship
  • The investment funds have been obtained from the National Fund for Environmental Protection and Water Management - We currently develop the technology and construction documentation.

Assumptions:

Production of ethanol and renewable energy from stillage and production of organic-mineral fertilizers using algal biomass. By using the Economizer SE Steam Explosion it is possible to use cellulosed substrates in a biogas plant, such as straw, which is a waste of agricultural production. Carbon dioxide which is a waste of the ethanol distillery is also used in the system, it will be integrated into the algal biomass, which then serve as a substrate for biogas plants as well as an intermediate product for the production of organic and mineral fertilizers. The biogas will be used for electricity production in cogeneration generators. Waste energy heat in the form of gases from cogeneration generators (in the system Economizer SE Steam Explosion) and energy recovered from technological processes occurring in agricultural distilleries will be used, among others for drying of substrates for organic and mineral fertilizers. Recovered heat will be also returned to an agricultural distillery.

System components:

  • Agricultural distillery farm with a capacity of 12 million of liters of ethanol per year.
  • Biogas plant installation.
  • Cogeneration generators with an electrical capacity: 2 MWe.
  • Installation for producing of organic and mineral fertilizers.
  • Lagoons (ground tanks): a magazine on the digestate mass and a culture of algal biomass.

Results:

Organic waste disposal system, effect of which will be renewable energy: electrical (for their own use and for sale) and heat. Utilization of carbon dioxide in the algal lagoons permits to obtain an additional product in the form of organic fertilizer. The proposed technology will allow to the production of ethanol from cellulose raw material (synonymous with starch), which will be the bio-component for fuel. The system was designed to optimize the use of all products produced at the plant and to reduce its impact on the natural environment to an absolute minimum.

Manufactured Products:

  • ethanol (produced from raw starch),
  • electricity (produced from renewable energy sources such as biogas produced in the biogas plant from substrates, ie stillage, straw),
  • heat energy (produced in combination with electricity and recovered from distillery processes),
  • organic and mineral fertilizers (substrates: digestate mass created as a waste in the technological process of biogas plant, algal biomass),

Patent:

This technological system was submitted to the Patent Office of the Republic of Poland as "A method of electricity, heat energy, fertilizer and/or feed producing and ethanol producing from agricultural waste products in agro-processing industry" and registered under number P385950.
