A novel ammonia-based CO2 capture process hybrid ammonia absorption refrigeration.

This paper proposed a novel ammonia-based CO 2 capture process hybrid ammonia absorption refrigeration to recovery escaped ammonia in the desorption process. The evaporated ammonia was separated with CO 2 via gas-liquid phase, and throttled to produce cooling load. The phase envelope of the CO 2 and NH 3 mixture was investigated to guide the design of the parameters. A preliminary thermodynamic performance was presented to evaluated the performance. The results showed that the regenerator can regenerate CO 2 with a ratio of 90% and this process can produce a cooling load of 113.3 MW. The parameter study indicated that it is competitive with the chilled ammonia process. [ABSTRACT FROM AUTHOR]
