花格管线自改扩建以来,由于输量的要求,不可避免会采用节流工艺。节流工艺极易损坏节流设备,同时也在很大程度上降低能源的利用效率。本文着重根据花格管线2009年1月份的一次节流过程,应用热力学第二定律进行节流工艺的计算与分析,得出节流能耗和经济损失,并提出了改进建议。)206.54(t20206.54(6953.01.859 t dtG204.6467mGQ7.322)206.54(t2026.54(6953.01.859 t tG204.6467GQ7.32212.t201.859t)206.54(t206.54(6953.01.859 t G20.6467GQ322
Grate pipeline since the expansion and expansion, due to the volume requirements, will inevitably use throttling process. Throttling process can easily damage the throttling equipment, but also to a large extent reduce the efficiency of energy use. This paper focuses on the calculation of the throttling process according to the first throttling process of the Grate pipeline in January 2009 and the second law of thermodynamics, and draws out the throttling energy consumption and economic loss, and puts forward some suggestions for improvement. ) 206.54 (t20206.54 (6953.01.859 t dtG204.6467mGQ7.322) 206.54 (t2026.54 (6953.01.859 t tG204.6467GQ7.32212.t201.859t) 206.54 (t206.54 (6953.01.859 t G20.6467GQ322
