INSTALLATION FOR OBTAINING BIOMASS BY MEANS OF THE CULTURE OF ALGAE AND OBTAINING A BIOREFINED PRODUCT FOR THE PRODUCTION OF BIO-OIL AND BIOPRODUCTS AND A METHOD FOR OBTAINING SAME

摘要

The present invention describes an installation for obtaining biomass by means of the culture of algae and obtaining a biorefined product for the production of bio-oil and bioproducts and the method for obtaining same by means of a closed axenic process in photounits. In the installation a culture medium is recreated that is similar to that which may be encountered in natural marine waters where the microorganisms develop and which is based on the use of seawater or brine, natural or artificial solar radiation, vitamins, nutrients, a stationary CO₂ supply and on recirculation of both CO₂ and water produced in all intermediate steps of the process. The production method allows the possibility, in the installation, for the provision of divisions of the photounits such that different classes of single-cell microalgae can be cultured therein, i.e., in the phototubes making up said units there is only one type of single-cell alga. Extractions are performed in cycles of 12 to 16 hour from the first biomass extraction therefore the production of bionutrient and bioenergetic products occurs continuously and a 95% biomass production yield is obtained.
