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 not only of CO₂ but also of water produced in all intermediate steps in the process. The production method allows the possibility, in the installation, for the provision of divisions of the photounits such that therein it is possible to culture different types of single-cell microalgae, i.e. in the phototubes that make up said units there is only one type of single-cell alga. Extractions are performed over cycles of 12 to 16 hours from the first extraction of biomass, and therefore the production of bionutrient and bioenergetic products occurs continuously and there is a 95% biomass production yield.
