Algae cultivation Using Flue gas

[mathu]

Can algae withstand the high temperatures in the flue gases?

Hai Mathu,

The capacity of algae to withstand high temperature is based on the algae you choose. Normally Algae will not withstand the temperature of flue gas which is why the flue gas is passed through a pretreatment chamber where the temperature of flue gas is reduced. In some cases a temporary underground storage of flue gas is preferred.

Hi,
Here is one interesting article on blue-green algae - Chroogloeocystis siderophila living in hot stream at Yellowstone.

Hi,
The temperature of flue gas is about 300 C and also the presence of SO2 and Nox is also toxic to algae culture. The flue gas need to be Desulphurized, and cooled before entering algae pond. Seambiotic says they use seawater for cooling flue gas. What is the exact pretreatment process used? What will be the cost of such processes?

Why can't we use the flue gas cooling water to cultivate algae that can grow in hot waters...Is there any major issues?? Is it possible?

Did you see this article in oilgae site?

Here is one company attempting to grow marine algae using available wastes of coal burning power plants, namely, flue gas and turbine cooling seawater

Companies are attempting to use cement plant emission for algae cultivation but cement Cement Kiln Emissions are known to have mercury, arsenic, lead, cadmium... etc, Can algae withstand such toxic heavy metals? Are these heavy metals taken up by algae?

[greengold09]

you are right...GreenFuel Technologies Corporation, announced algae farming technologies for Holcim cement plant near Jerez, Spain in October 21, 2008.

Hi,
I read a research paper on "Heavy Metal Bioaccumulation and Toxicity with Special Reference to Microalgae". It looks like Metal
ions are adsorbed first to the surface of cells by the interactions between the metal ions and metal-functional groups such as carboxyl, phosphate, hydroxyl, amino,sulphur, sulphide, thiol, etc., present in the cell wall and then they penetrate the cell membrane and enter the cells.
