摘要
为了解决船用燃料油产品因原料油调合组分间相容性差而出现的质量稳定性问题,基于相容性原则计算各原料油的适配比例,以其作为燃料油配方测算方案的限制条件,进而以低成本为目标函数经计算得到优化配方。对比经验配方和优化配方调合燃料油产品的稳定性,结果表明:与经验配方相比,按优化配方调合的新样品(样品标记为0d)及其在静置15 d后样品(样品标记为15d)的斑点试验结果均明显更优,稳定性更好;老化后,按优化配方调合样品(0d及15d)的梯度密度差均小于10 kg/m^(3),斑点试验结果为2级,长期储存后燃料油性质稳定。
In order to solve the problem of quality stability of blended marine fuel oil products due to the poor compatibility of the feedstock,based on the compatibility principle,the matching proportion of each feedstock was calculated as the limiting condition of the fuel oil formula calculation,and then the optimized formula was obtained by taking the low cost as the objective function.The results showed that compared with the empirical formula,the optimized formula could improve the stability of the blended fuel oil,the spot test results of the fresh samples(0d)prepared by the optimized formula and the samples left for 15 days(15d)showed that the new samples had better stability,the gradient density difference of the blended samples(0d and 15d)was less than 10 kg/m^(3),and the spot test results were 2 grades.The fuel oil properties were stable after long-term storage.
