【摘要】 使用ASPEN-plus对德士古合成氨流程进行了模拟计算,通过分析法对流程进行了更为全面和深入的能耗分析,考察了德士古合成氨工艺流程的大能耗单元,发现了合成氨工业进一步节能的潜力所在。从能量的梯级利用概念出发对分析结果进行讨论,进而指出该系统节能降耗的新途径和方向。结果表明,分析方法可成为未来节能工业应用的主要方法。更多还原

【Abstract】 Introduces current situation of synthetic ammonia technology with an emphasis on energy saving. On the basis of an exergy analysis of Texaco synthetic ammonia technology simulated by ASPEN-plus, the chief energy consumption units are located and further potentials of energy saving pointed out. From the view point of energy cascade utilization, the result of exergy analysis is discussed and new way of energy saving brought forth. The results indicate that exergy analysis will become one of the more promising techniques in use in the future industrial energy saving.更多还原
