Sargas Technology – Carbon Capture Under $20 Per Ton?
It uses a system of pressurised filters, absorbers and condensers.The technology, developed by Sargas Technology Group, can also remove 95 per cent of carbon dioxide from a flue gas stream, more than the 90 per cent of most carbon capture technologies, the inventors claim.
The technology requires the flue gas to be under pressure to work, so it cannot be used with existing plants where exhaust gases are at atmospheric pressure. However it can be used with new pressurised fluidized bed combustion systems, which are currently used in Sweden and Germany, and it can be used with new natural gas plants.
The company wants to build a 400 megawatt coal fired power plant to supply electricity for metals smelters in Norway, working together with aluminium company Alcan, Norwegian oil company Norsk Hydro, French metals producer Eramet and Norwegian group Tinfos.
