How do you extract oil from algae?
Oil press or Mechanical press The oil can be extracted from algae using a mechanical press, as seen in figure 1. This process—which forces the algal paste into a nozzle that removes oil and expels much drier biomass—can extract up to 70% of the algal oil, but generally requires a dry algae feedstock. Dry algae is the product of dewatering.
What is dry algae?
Dry algae is the product of dewatering. This process is commonly combined with the hexane solvent method. Oil from the algal biomass dissolves into the hexane solvent; a six-carbon chain molecule. Then the oil is cleaned through distillation, and the solvent is recycled through further processes.
How does hexane extract oil from algae?
Basically a two-part process, the hexane solvent method (combined with pressing the algae) extracts up to 95 percent of oil from algae. First, the press squeezes out the oil. Then, leftover algae is mixed with hexane, filtered and cleaned so there’s no chemical left in the oil.
