• What is the energy supply scheme of sunflower seed oil mill?
  • Energy supply scheme of Sunflower Seed Oil Mill (developed by author). As can be seen, the best strategy for CHP development is to cover heat demand by CHP. As compared with husk utilization for heat production only, it allows mills to increase total income by 21¨C23% and reduce carbon dioxide emission by 70¨C73%.
  • How much husk does a Ukrainian sunflower oil mill produce?
  • For Ukrainian sunflower seed oil mills the first component ranges from 48 to 96 kg per ton of seed processed. The second component ranges from 37 to 77 kg per ton of seed processed. According to our calculation, one ton of husk (used for steam production) reduces carbon dioxide emission and this range is from 790.10 to 1162.53 kg ( Table 2 ).
  • How can a sunflower oil mill increase the competitiveness of the industry?
  • To raise the competitiveness of the industry, reducing energy costs is paramount. It can be reached by means of biomass utilisation. Sunflower oil mills produce a by-product (husk). Husk and products (oil and cake) can be used to generate electricity and/or heat.
  • Are sunflower oil mills a good investment?
  • Sunflower oil mills produce a by-product (husk). Husk and products (oil and cake) can be used to generate electricity and/or heat. This substitutes the energy resources sold (fossil fuels and electricity) and reduces greenhouse gas emission. Moreover, biomass CHPs could improve the stability and reliability of the electrical grid.
  • How much carbon dioxide does a sunflower oil mill produce?
  • For Ukrainian sunflower seed oil mills the first component ranges from 48 to 96 kg per ton of seed processed. The second component ranges from 37 to 77 kg per ton of seed processed. dioxide emission and this range is from 790.10 to 1162.53 kg (Table 2). It corresponds to 51.3¨C75.5 kg of carbon dioxide per one GJ of thermal energy.
  • Do Ukrainian sunflower oil mills use a lot of electricity?
  • Specifically, the electricity and heat consumption of Ukrainian sunflower oil mills is investigated. Different options of cogeneration systems are analyzed. The preferable mode of combustion-based husk combined heat and power plants is to meet their own heat demand and to sell surplus electricity.
