Recent advances in energy-efficient and regenerative SO2 absorption
The absorption of NH 3 is procedurally quite similar to SO 2, the differences lie in their absorption capacities. The NH 3 absorption capacity range is around 1.2 – 10.4 mol NH 3 /kg using inorganic salt-based DES while the SO 2 absorption capacity range is around 0.3 – 0.6 g SO 2 /g using inorganic salt based DES [30], [43], [44].
