TL;DR: In this paper, the effects of ammonia concentration, L/G, gas flow rate, gas temperature, CO2 partial pressure and other factors on the volumetric overall mass transfer coefficient (KGaV), the gas phase mass transfer coefficients (kG) and the effective mass transfer cross-sectional area (aV) were investigated with ammonia solution as the absorbent in homemade spray tower.

TL;DR: In this paper, the main existing methods to control the escape of ammonia were analyzed and it was concluded that controlling the source of ammonia is feasible and adding some organic additives can inhibit the escape and enhance the CO2 removal to some extent.

TL;DR: In this paper, a method for collecting SO2 and CO2 in flue gas from coal-fired power plant and producing chemical products, comprises the process of desulfurization and decarbonization by taking ammonia as an absorbent and the process by producing soda ash and other chemical products by taking sodium chloride as a crystals forming agent.

TL;DR: Wang et al. as mentioned in this paper investigated the problem of ammonia escape during carbon capture using an ammonia solution and showed that Co(II) complexation with free ammonia in the absorbent solution forms [Co (NH3) 6]2+, which can significantly reduce the amount of ammonia escaping, and has no significant effects on the carbon capture process.

TL;DR: In this paper, metal ions are used as an additive and a chosen inhibitor mainly comprises Co(II), Cu(II, Zn(II) and Ni(II); the method has a high ammonia escape control rate; when the concentration of the additive is 0.0025 to 0.1 mol/L, an optimal inhibition effect is obtained, an ammonia escape reduced rate can reach 40 to 65%, and a substantial ammonia inhibition effect can be maintained for a long time.
