Grow and collect micro-algae as a source of bio-fuel or industrial products; 2. Desalinate sea, brackish or waste water for industrial use; 3. Extract carbon dioxide from flue gas. The method employs two modified greenhouses, one for growing algae and/or preheating air and aqueous liquid mixtures, and the other for harvesting and drying algae or other finely dispersed solids content of slurries. The processes are controlled by varying the degree of atomization with linear nozzles. In the first greenhouse, linear nozzles spray liquid sheets and coarse droplets to absorb solar energy. In the second greenhouse, linear nozzles finely atomize suspensions for solar drying. The method and greenhouses are also utilized for solar desalination of water and for extraction carbon dioxide coupled with its absorption in magnesium hydroxide slurry.

  • Publication number: 20100162620
    Abstract: In algae, the conditions for optimal production of biomass are different than the optimal conditions for oil/lipid production. Conventional processes require that both steps be optimized simultaneously which is necessarily sub optimal. The invention provides systems and processes for optimizing each type of production separately and independently, thereby improving overall production of oil, lipids and other useful products. This process is advantageous because it allows the optimization of the individual steps and growth phases in the production of oil from biomass. This allows the use of different feedstocks for various process steps.

  • Publication number: 20070155006
    Abstract: An invention proposes a construction of a photobioreactor, which is based on application of parallel sets of multi-level troughs intended for flowing a microalgae suspension, these troughs are irradiated therewith by the sun light. The troughs are arranged in each set one above the other horizontally or with a small inclination to the horizontal plane. The width of the gaps between the neighboring sets of the troughs is significantly larger than the width of the troughs themselves; at the same time, the sum of the widths of each troughs' set is significantly higher (up to several times) than the width of the above-mentioned gap. Optical elements, which reflect and disperse the light, are positioned between the neighboring sets of the troughs. In addition, multi-tubular elements with headers may be used in the proposed construction instead of the troughs.
