| Abstract: | A new process featuring single vacuum furnace and two stage evacuation process and its commercial application in the vacuum distillation tower in the refinery of Jinling Petrochemical Company was introduced.High vacuum has been maintained for 4 years in the unit with a capacity of 2,800,000 tons per year,which resulted in a 1.6% increase in the total distillation yield and over 10 MMRMBY in extra.Effects of costruction of lower section of the vacuum distillation tower on both quality and yield of deep distillated oil were pointed out. |

| Keywords: | atmospheric vacuum distillation unit vacuum distillation tower multi stage vacuum enhancement vacuum gas oil yield commercial scale |
