Definitions

  • Microalgae, and other phototrophic microorganisms are a diverse group of microorganisms that reside in marine and freshwater habitats.
  • the key process for microalgae growth is photosynthesis, a process that uses light energy to convert C0 2, water and nutrients into hydrocarbons, while oxygen is being discharged.
  • Microalgae have been investigated as energy source for several decades with the US DOE's Aquatic Species Program (1978-1996) and the Japanese RITE Program (1990-2000) being the most prominent research investments.
  • the driving force behind most of this research is the high biomass yield from microalgae compared to terrestrial feedstock. Biomass yield from microalgae ranges 7-31 times higher than oil palm, the best oil yielding terrestrial plant (Kent and Andrews, 2007).
  • their naturally high lipid content (20-50% of dry weight) renders cultivation of microalgae interesting as source for biofuel production.
  • bio- energy production from algae culture has not gained a competitive edge so far, simply because the production cost at present is too high.
  • Micro-algal biomass contains approximately 50% carbon by dry weight (Christi, 2007) depending on the species. Since phototrophic algae species use C0 2 as their sole carbon source, production of 100 tons of algal biomass fixes roughly 183 tons of carbon dioxide. Most microalgae can tolerate high levels of C0 2 , typically up to 150 000 ppmv (Bilanovic et al., 2009). However, the pH-decreasing effect of C0 2 dissolution must be buffered as most species achieve highest productivity at neutral pH.
  • Microalgae are grown in an aqueous growth medium that provides the inorganic elements constituting the algal cell. Carbon, nitrogen and phosphorous are the most important nutrients (macronutrients) for algae cultivation. Diatom algae require silica as macronutrient to build their outer cell walls. Other (potentially) important nutrients include calcium, magnesium, sodium, potassium, and sulphur. Micronutrients, trace elements required by plants and animals in very small quantities, include manganese, copper, zinc, cobalt, and molybdenum (Horn and Goldman 1994). The growth medium must contain nutrients in significant excess.
  • phosphorus -normally added as phosphate- forms complexes with metal ions, rendering part of the added phosphorous unavailable to uptake by algae cells.
  • fast-growing species prefer ammonium over nitrate as nitrogen source, some microalgae can fix nitrogen in the form of NO x (Brennan and Owende, 2010).
  • NO x Bacillus and Owende, 2010
  • the growth medium In order to minimize nutrient consumption, the growth medium must be recycled efficiently and nutrients consumed by algae growth must be replenished.
  • Today, profitable production of microalgae raw material used in refined products of the medicine, pharmacy, dietary supplement and cosmetics industries, is very profitable. Raw materials used as ingredients in fish and animal feeds may also in some cases be profitable.
  • An algae plant of this size would yield about 550 000 tons of dry algae mass per year.
  • Minimal nutrient consumption estimated based on an average elemental algae composition determined by ECN (www.ecn.nl/phyllis) yields: Table 1. Annual nutrient consumption for binding 1 Mt C0 2 in algae.
  • Figure 6 describes a process where carbon nutrients is obtained from carbonate salts, directly form crushed carbonate rocks in seawater slurry, with C0 2 only from air.
  • the resulting liquid is adjusted, by mixing in, lacking ingredients from rocks of suitable composition dissolved in nitric acid, or other mineral acid, to achieve an optimal nutrient composition tailor-made for the growth of different algae species.
  • the naturally occurring rocks are selected as to contain a convenient mixture of minerals in relation to the algae nutrition needs, which may differ from algae specie to algae specie .
  • the naturally occurring rocks may include apatite containing rocks typically selected among plagifoyaite, nepheline-syenite and carbonatite, or any combination of same.
  • a combination of rock types, compositions and acid(s) for their dissolving are selected so as to tailor the blend of minerals for a particular type of algae.

Abstract

L'invention concerne un procédé pour la production d'une source nutritive aqueuse pour des fermes aquacoles de macro et micro algues et la source nutritive ainsi formée. Des roches contenant du phosphore sont dissoutes dans au moins un acide minéral pour donner une solution contenant un mélange d'ions des minéraux présents dans les roches et dans l'acide sous une forme assimilable par les algues et du carbone est ajouté sous la forme de C02, d'acide carbonique, ou de sels de carbonate. L'invention concerne également un procédé pour approvisionner une ferme aquacole d'algues avec ladite source nutritive.
