Problems solved by technology

Such open ponds are cheaper than closed systems, but they also have disadvantages: the sun only reaches the algae close to the surface of the water, the water evaporates easily, and the temperature is difficult to control
The risk of contamination is also greater than with closed systems

Abstract

A method of algal oil production including the steps of: control growing to provide intensive growth to supply starting means for algae farming. Farming algae from using primarily sunlight. Processing algae produced from the farmed algae preferably using a wet extraction process: and wherein at least one of the steps includes use of a bag able to be interconnected to gas or liquid flows of at least one of water, CO2, oxygen or air.

Description

technical field [0001] The present invention relates to a method and system for the growth of algae for biofuel production, and more particularly to a device for promoting the growth of algae for biofuel production. Background technique [0002] Algae are a good source of biofuel because they are fast growing, rich in vegetable oils, and can be grown in containers or ponds with minimal use of land and fresh water. Algae can provide sustainable feedstock for diesel fuel production, and CO 2 Emissions are very low. [0003] Biofuel (alkyl esters) is a clean-burning diesel fuel made from, for example, unused or recycled waste vegetable oil, and can directly replace diesel as a pure fuel (B100) or as an oxygenated additive (typically 5%-20 % B5 and B20) from natural, renewable resources. The largest producer and user of biodiesel is Europe. Usually made from canola (canola) oil. Additional sources of feedstock for biodiesel production include palm oil, tallow, and all waste...
