炼油厂自耗能中,燃料油占75%左右,降低自用燃料,无疑能提供更多的商品能源.1979年全国炼油厂消耗燃料油520万吨,其中工艺加热炉占261万吨,相当于一座中型炼油厂一年的原油加工量.南京炼油厂自1980年开始逐步实现各项节能措施:一方面加强工艺装置的原料换热,减少工艺炉的热负荷.一方面利用工艺装置的余热发生蒸汽,使部分工艺装置蒸汽自给,减少了蒸汽锅炉的供汽.全厂炼油能耗逐年下降(参见表1). Refineries in the refineries, the fuel oil accounted for about 75%, reducing self-use of fuel, will undoubtedly provide more energy products.In 1979 the national oil refinery consumed 5.2 million tons of fuel oil, of which 2.61 million tons of process furnace, which is equivalent to A medium-sized oil refinery processing crude oil a year.Nanjing Refinery from 1980 to gradually achieve the various energy-saving measures: on the one hand, to strengthen the process equipment, raw materials, heat transfer, reducing furnace heat load.On the one hand, the use of waste heat from the process unit Steam, so that part of the process equipment steam self-sufficiency, reducing the steam boiler for steam. The whole plant refining energy consumption decreased year by year (see Table 1).
