掺炼南帕斯凝析油的沙轻混合原油性质分析
|
摘要
随着市场对石油产品日益增长的需求,炼油厂加工进口原油的种类越来越多,为炼厂提高拔出率创造机会的同时,也给炼油厂带来了许多困难。现以沙轻原油掺炼南帕斯凝析油为研究案例,分析沙轻原油和南帕斯凝析油的基本性质及组成特点,并对掺配比为5%、8%、12%的混合原油进行了实沸点蒸馏、窄馏分酸值分布、窄馏分总硫分布和窄馏分氯值分布的实验研究,结果表明:掺炼南帕斯凝析油的沙轻原油提高了收率,降低生产成本提高了经济效益、同时优化了含硫、氯等腐蚀性物质的分布曲线,使装置的抗腐蚀性能得到提升。
The basic properties and composition characteristics of light crude from Saudi Arabia and South Pars condensate were analyzed. The real boiling point distillation and narrow fraction of light crude from Saudi Arabia blended with 5%, 8% and 12% South Pars condensate were investigated as well as the acid value distribution, the narrow sulfur fraction total sulfur distribution and the narrow fraction chlorine value distribution. The results showed that blending the light crude from Saudi Arabia with South Pars condensate increased the yield, and the acid value was also improved. At the same time, the total sulfur content and total chlorine content after blending were also evaluated.
