The document describes an industrial plant for producing biodiesel from algae. It discusses the multi-step process including growing algae phototrophically in photobioreactors, extracting the algal oil, and converting the oil to biodiesel. Key aspects of the process include nutrient delivery and monitoring, light exposure and mixing to maximize photosynthesis, and mechanical designs to optimize the culture and extraction. The biodiesel produced can replace diesel fuel completely and meets European environmental regulations.

1. B i o – D i e s e l OilFromAlgae “TheFirst Industrial Plant”

2. Over the past seven years RecursosRenovablesAlternativos has been studying and developing a process for the production of Biodiesel from algae.

3. The first step of this process is a close photobioreactor capable of achieving a very high volumetric productivity, providing at the same time, the necessary reliability and stability to the cultivation process and resulting in a very cost-effective culture system.

4. Since phototrophic microorganisms are highly diverse in their morphology, one of our first concerns has been the knowledge of the physiology in mass culture.

5. Nutritional factors are some of the important issues that we have take in consideration. The understanding of macro nutrients like carbon, nitrogen and phosphorus, the role that they play in cellular metabolic processes, the effect of the depletion of these elements, the role of essential trace mineral elements like iron that is very important in cellular biochemical composition and its implication in fundamental processes such as photosynthesis has been our priority.

6. The other major issue involved in mass cultivation of photoautotrophicmicro algae concerns effective use ofstrong light for photosynthetic productivity of cell mass and secondary metabolites.

7. The knowledge of light penetration depth as a function of cell density, the effect of mixing cultures, the design of the mixing processes inside the photobioreactor, has also been a priority for us. The effective use of light-dark cycle frequencies, the online monitoring of photosynthetic activity through the measuring of dissolved oxygen is just some of the other parameters that we have to evaluate the effectiveness of our process.

8. The third major issue and also very important part of our technology, are the different mechanical designs that we have included in our photobioreactor, example of this is the CO2 injection system, the design of the culture mixing process, the fluid dynamics of the culture medium, the design of degassing, the state of the art process control system that monitors the nutrients consumption through the photobioreactor, the re-injection of the necessary macro nutrients and trace minerals, the dewatering system, the online monitoring of the re-injected water, etc…

9. One of our most important capabilities is the use of one of our patented processes to lice the algae; this process is mechanical and a very cost effective method that allow us to extract the lipids from the disrupted algae.

10. The fourth major issue concerns state of the art biodiesel production capabilities; the process that we have is a continuous process andis focused on high technology and the compliance of all the Europeanregulations. Enclosed circuit production process therefore it does not become polluted nor pollutes the environment in any way Thewaterisrecycled
