| titleOfInvention | Ammonia-urea production process and equipment |
| abstract | The liquefied ammonia that a kind of technique for ammonia urea production, wherein ammonia section generate is supplied directly to urea section in ammonia synthesis pressure, and the liquefied ammonia is purified by following steps under high pressure：The cooling liquefied ammonia（20）Obtain cooling flows of liquid ammonia（21）；Separation includes the gas fraction of hydrogen and nitrogen from the liquefied ammonia of the cooling（22）, obtain the liquefied ammonia of the purification under high pressure（23）；After detaching the gas fraction, the liquefied ammonia of the purification is reheated（23）, obtain the liquefied ammonia of the purification of reheating of the temperature suitable for supplying the synthesis process of urea（24）.The application also handle include ammonia cooler, gas-liquid separator and ammonia reheater equipment, the method for additionally providing a kind of existing ammonia urea equipment of repacking. |
