There is also a need to provide concentrated CO2 to increase the rate of production. 3. Closed loop system : Another obstacle preventing widespread mass production of algae for biofuel production has been the equipment and structures needed to begin growing algae in large quantities. Maximum use of existing agriculture processes and hardware is the goal. In a closed system (not exposed to open air) there is not the problem of contamination by other organisms blown in by the air. The problem for a closed system is finding a cheap source of sterile CO2. Several experimenters have found the CO2 from a smokestack works well for growing algae. To be economical, some experts think that algae farming for biofuels will have to be done as part of cogeneration, where it can make use of waste heat, and help soak up pollution. Oil Extraction From Algae: While more efficient processes are emerging, a simple process is to use a press to extract a large percentage (70-75%) of the oils out of algae. The remaining pulp can be mixed with cyclo-hexane to extract the remaining oil content. Centrifuges A centrifuge is a useful device for both bio-lipid extraction from algae
