在某公司焦化车间大检修期间，采用中国石油大学开发的"高苛刻度裂化技术"，在焦化加热炉总体结构不变的条件下，对该公司的100万t/a焦化装置加热炉进行优化改造。改造后加热炉炉膛温度平均降低约50℃，汽柴油收率提高4.22%，焦炭产率降低1.5%，加热炉热效率由91.05%提高至92.34%。可节省标油320 t/a，节能效果显著。

During the overhaul on the coking plant of a certain company,the high severity cracking technology that is developed by China University of Petroleum is used to renovate and optimize the heating furnace of the 1 million t/a coking unit in the company while remains the overall structure of the furnace unchanged.After the renovation,the average temperature of the furnace chamber decreases by about 50℃,the total yield rate of gasoline and diesel increases by 4.22%,the yield of coke decreases by 1.5%,and the thermal efficiency of the furnace increases from 91.05% to 92.34%.Through renovation,320 tons of standard oil can be saved per year,representing a remarkable energy saving effect.
