Abstract
A method for processing algae-based products using flue gas heat includes mixing flue gas with water, receiving a heated gas in a first enclosure of a heat exchanger, receiving an algal paste in a second enclosure of the heat exchanger, introducing an organic solvent to the algal paste, extracting an algal oil and a plurality of algal shells from the algal paste by dissipating heat from the first enclosure to the second enclosure; and extracting the algal oil from the organic solvent and the algal shells.
Claims14
A method for processing algae, comprising:
- receiving a heated flue gas in a first enclosure of a heat exchanger;
- receiving an algal paste in a second enclosure of the heat exchanger;
- introducing an organic solvent to the algal paste;
- extracting an algal oil and a plurality of algal shells from the algal paste by dissipating heat from the first enclosure to the second enclosure;
- and
- extracting the algal oil from the organic solvent and the algal shells;
- wherein the flue gas is a gas rich in CO2.

A method for processing algae, comprising:
- harvesting a plurality of algae organisms by skimming a surface of a water in each processing cell of an algae growing system to collect algae present on the water surface;
- producing an algal paste by de-watering the plurality of algae organisms;
- receiving a heated flue gas in a first enclosure of a heat exchanger;
- receiving the algal paste in a second enclosure of the heat exchanger;
- introducing an organic solvent to the algal paste;
- extracting an algal oil and a plurality of algal shells from the algal paste by dissipating heat from the first enclosure to the second enclosure;
- returning a supernatant byproduct of extracting the algal oil from the algal paste to the algae growing system;
- receiving the organic solvent and the algal shells in a third enclosure of the heat exchanger;
- and
- extracting the algal oil from the organic solvent and the algal shells;
- wherein the heated flue gas is a gas rich in CO2.
