摘要：为使原油稳定经济效益最大化，以某处理站原油全烃色谱分析实验数据及现场实际运行工况为基确，采用AspenHYSYS软件建立计算模型，优化三种内蒸工艺塔预气冷部温度并对工艺进行适应性分析。结果表明：塔预气存在最低冷却温度，使原油稳定产品收益达到最大。负压闪蒸工艺塔顶气携带C，含量多，不凝气产量高；微正压闪燕工艺不凝气产品质量最好，轻组分含量高、重组分含量低：加热闪蒸工艺塔预气携带重组分含量高，C，~C，的质量分数低；原油与轻烃的动态价格关系决定闪蒸工艺的选择。

Abstract: In order to maximize the economic benefit of crude oil stabilization, based on the experimental data of the total hydrocarbon chromatographic analysis and the actual operating conditions of the treatment station, calculation model is set up by using Aspen HYSYS software to optimize overhead gas cooling temperature of three kinds of flash process and adaptability analysis of the process is conducted as well. The results shows that the overhead gas has a minimum cooling temperature that the product stable yield will reach the maximum; noncondensable gas production of negative pressure flash process is high and the content of overhead gas carrying C, is high; noncondensable gas product of micro positive pressure flash process is best, the content of light component is high and low of heavier component. The content of overhead gas heavier component of heating flash process is high and the mass fraction of C, C, is low; the dynamic price relationship between crude oil and light hydrocarbon determines the choice of flashing process.
