常减压装置是在原油加工过程中耗能最多的装置。因此,要降低炼油工业的能耗,提高热能利用水平,必须抓住这个“大户头”。原油在常减压蒸馏装置中消耗的能量指标见表1 (按石油部规定,燃料油1公斤=10,000千卡,电1度=3,400千卡,蒸汽1公斤=780千卡,水1吨=1度电折算)。可 Atmospheric vacuum unit is the most energy-consuming device in the processing of crude oil. Therefore, to reduce the energy consumption of the oil refining industry, improve the level of heat utilization, we must seize this “big head.” Crude oil consumed in the atmospheric and vacuum distillation unit energy indicators shown in Table 1 (according to the provisions of the Ministry of oil, fuel oil 1 kg = 10,000 kcal, electricity 1 degree = 3,400 kcal, steam 1 kg = 780 kcal, water 1 ton = 1 degree conversion). can
