In response of problems such as ammonia escape

high regenerated energy and low absorbed rate in the late stage

which exist in the research of carbon capture by ammonia now

this paper presents a novel process of carbon capture by ammonia with reinforced crystallization

using a new type of aqueous ammonia-ethanol mixing absorbent. The effect of absorption and crystalline regularity under different absorbent ingredients

different absorption temperatures

different flue gas flow

and different CO2 volume fraction is studied using a semi-continuous bubbling reaction system. The experimental results show that mixing absorbent with relatively high ratio of ethanol

relatively low absorption temperature

and higher gas flow and larger volume fraction of CO2 will be favorable for strengthening of process

including that the appearing time of crystals in the absorbent could bring forward and the ratio of ammonia account in the crystals to the initial total ammonia could be up to 38.75% as well as the CO2 absorption capacity was improved significantly compared to pure aqueous ammonia. Novel ideas presented in this paper could be that a carbon capture process by ammonia with reinforced crystallization is suggested

and better conditions were given for improving absorption and reducing consumption of desorption energy. All basic data and results provided by this paper could be useful for further study of this new process.
