节油剂在常减压蒸馏装置加热炉中的应用

Application of oil-saving additive in heating furnace of atmospheric and vacuum distillation unit

以重质燃料油为常减压蒸馏装置加热炉的燃料,在其中加入节油剂,于正常生产的条件下,可提高装置加热炉的热效率。工业应用表明,加入重质燃料油节油剂后,可以降低燃料油黏度,当加剂质量分数为0.30%时,黏度下降79.7%;第一套常减压装置常压加热炉、第二套常减压装置常压加热炉及其减压加热炉热效率较未添加者分别提高1.05,1.38,1.60个百分点。

The thermal efficiency of heating furnaces with heavy fuel oil as fuel oil in atmospheric and vacuum distillation unit was improved by adding oil-saving additive under the normal operating condition.The industrial application results showed that when the mass fraction of oil-saving additive was 0.3%,the viscosity of heavy fuel oil decreased by 79.7%,and the thermal efficiency increased by 1.05,1.38,1.60 percentage points respectively for the heating furnaces of the first and the second atmospheric distillation units,and the second vacuum distillation unit compared to before adding the additive.
