Applicability and potential

・・・・Applicable for existing and new-installed power plants

・・・・Potential for the reduction of cost and power

consumption by scaling-up of ASU and the integration of

total process

Process・・・・Installation of air separation unit

・・・・Flame temperature is adjusted by flue gas

recirculation

・・・・NOx emission is reduced by flue gas

recirculation

・・・・DeNOx and DeSOx will be compacted in case of

new-installed power plant

Feature

・・・・CO2 is major component in the flue gas

・・・・Amount of flue gas to CO2 purification can be reduced

to be almost one forth

Oxyfuel combustion ;

In coal fired power plant, coal combustion by oxygen in stead of air make it possible

to be concentrated of CO2 more than 90% theoretically in the flue gas.
