Consider improved scrubbing designs for acid gases

The solubility of sodium salts of H 2 S and CO 2 are functions of pH and temperature. Sodium bisulfide has a high solubility in water (perhaps 40+ wt%), but sodium sulfide is a low solubility (13.6 wt% at 20C). Sodium bicarbonate is even less soluble (9.6 wt%).3 In mixed systems, the common-ion effect can further lower these solubilities.
