Industrial Symbiosis-Algae and Emissions

[KALAKURASA PRASHANTH]

As we are well aware of the fact that the emissions from most of the industries contain carbon-di-oxide in high concentrations. If we can divert this gas to algae contain in biotubes we can regenerate fuel and can reuse it in industry. My doubt is that , Can we separate carbon dioxide from rest of the gases in mixture. If so , how?

This idea is definitely worth exploring. I found

It would be important to do a expenditure-income analysis.

The flue gas do not contain high CO2 concentration. Its around 17-18% only. At time it will be less than 10 also. Others are O2, CO, NOx, and more N2. Yes. its very much possible to diver this for cultivating algae and experiments have been conducted successfully to prove this. There are scrubbers available for purifying this. Commercially FLSmidth and other companies has the technology for scrubbing gases.
