摘要:
An integrated ammonia/urea process and a plant for carrying out the same. The process comprises recycling a high pressure purge stream made up mostly of air from the urea synthesis cycle to the autothermal reformer in a syngas production unit of the ammonia process. In such a manner, compression energy required for ammonia synthesis can be reduced since a portion of the high pressure air feed to the autothermal reactor is supplied by the urea purge stream recycle. In addition, the equipment needed to clean up the urea purge stream is largely eliminated.
