摘要
A process of CO2 removal from a flue gas, comprising: (a) contacting a flue gas with a CO2 lean ammonia-comprising medium to produce a CO2 rich ammonia-comprising medium; (b) heating the CO2 rich ammonia-comprising medium to produce a regenerated CO2 lean ammonia-comprising medium; and (c) supplying the regenerated CO2 lean ammonia-comprising medium to said absorber; (d) identifying a desired mole ratio of ammonia to CO2 of the CO2 lean ammonia-comprising medium; (e) predicting a desired temperature of regenerated CO2 lean ammonia-comprising medium present in a sump of a regeneration vessel or predicting a desired operating pressure of a regeneration vessel; (f) controlling the temperature of regenerated CO2 lean ammonia-comprising medium present in the sump of the regeneration vessel or the operating pressure of the regeneration vessel. A system for removal of CO2 from a flue gas, comprising: i.a. a control unit.
