<p>A CO2 separating system includes: a CO2 absorption tower which absorbs the CO2 from CO2-containing gas; a CO2-absorbing solution regeneration tower which regenerates the CO2-absorbing solution and is connected with a reboiler; a generator which has a first generating heat exchanger and a second generating heat exchanger; an absorber which contains an absorbing heat exchanger connected with said reboiler; a steam passage which connects the said generator with the said absorber; the inlet of the said first generating heat exchanger connects with the absorbing solution outlet at the bottom of the said CO2-absorbing solution regeneration tower; the outlet of the first generating heat exchanger connects with the absorbing solution inlet at the upper portion of the said CO2 absorption tower; the inlet of the second generating heat exchanger connects with gas outlet at the top of the said CO2-absorbing solution regeneration tower.</p> |
