Process for the preparation of urea |
摘要 |
Process for the preparation of urea from ammonia and carbon dioxide, wherein the waste gases released at virtually atmospheric pressure in a urea plant are compressed by an ejector driven by the waste gas from the high-pressure synthesis and are supplied to a medium-pressure absorber. The pressure of the waste gases is increased by 0.15-1 MPa.
