| titleOfInvention | A kind of synthetic ammonia separation process |
| abstract | The invention discloses a synthetic ammonia separation process, which comprises the following steps: S1) vapor-liquid separation of liquid ammonia after cooling synthetic ammonia gas; S2) unliquefied gas enters an absorption tower and dissolves into an absorbent to form an ammonia solution for discharge; S3) removes The gas after the ammonia is sent into the synthesis tower as a circulating gas; S4) ammonia solution goes out of the absorption tower into the desorption tower for desorption, forming a desorption gas and a regenerated absorbent; S5) the regenerated absorbent goes out of the desorption tower into the absorption tower, and further dissolves the ammonia gas; S6) carry out vapor-liquid separation after the stripping gas is discharged from the desorption tower, and separate out ammonia-rich condensate and ammonia-rich uncondensed gas; S7) condensate enters the desorption tower to participate in the desorption of the next cycle, and the uncondensed gas and After the synthetic ammonia gas in step S1 is mixed, it participates in gas-liquid separation to obtain liquid ammonia. The invention adopts the process of two-stage condensation ammonia separation coupled with absorbent absorption-desorption ammonia separation to deeply separate the ammonia gas in the ammonia synthesis gas, greatly reducing the residual ammonia gas concentration in the circulating gas, thereby increasing the net ammonia value. |
