PROCESS FOR THE PREPARATION OF AMMONIA |
摘要 |
Process for the preparation of ammonia from a hydrogen and nitrogen-containing synthesis gas comprising steps of (a) admixing to the synthesis gas recycle gas from an ammonia separation step (f) and (g); (b) pressurizing the admixed gas from step (a); (c) dividing the gas from step (b) into a first make up gas stream and a second make up gas stream; (d) introducing the first make up gas stream into a first ammonia reactor and withdrawing a first process stream being rich in ammonia; (e) introducing the second ammonia make up gas stream into a second ammonia reactor and withdrawing a second process stream being rich in ammonia; (f) separating ammonia from the first process stream and recycling the remainder of the process stream to step (a); (g) separating ammonia from the second process stream and recycling the remainder of the process stream to step (a); (h) combining separated ammonia from step (f) and step (g) and withdrawing an ammonia product stream. |
