The CANSOLV^® CO2 Capture System enables CO2 to be absorbed from the feed gas by counter-current contact with the regenerable absorbent in the absorption tower. Since CANSOLV Absorbent DC101™ reacts reversibly with CO2, multi-stage counter-current contacting is used to achieve maximum loading of the CO2 into the regenerable absorbent. The solvent is fed to the top of the absorption tower and as it flows down the tower it selectively reacts with CO2. At the bottom of the absorption tower, the CO2-laden or “rich” amine is pumped to a regeneration tower where it is heated to reverse the absorption reaction. As CANSOLV Absorbent DC101™ moves down the regeneration tower, it is gradually stripped of CO2. At the bottom, the CO2-depleted absorbent is referred to as “lean” amine. Sensible heat from the lean amine is then used to heat incoming rich amine to maximize heat recovery.
