独山子炼油厂常减压装置1985年一季度能耗为11.08万千卡/吨比1984年一季度能耗14.47万千卡/吨下降了3.39万千卡/吨.其原因是利用装置空冷器、间冷器大于120℃的低温热约570万千卡/时,用来加热动力锅炉给水和在冬季供给矿区居民热水取暖及厂内三个车间办公室的取暖,使得装置向外输热3～4万千卡/吨,全年约降低能耗1.5万千卡/吨. Dushanzi refinery atmospheric vacuum unit in the first quarter of 1985, energy consumption of 110,800 kcal / ton than in the first quarter of 1984 energy 144,700 kcal / ton down 33,900 kcal / ton due to the use of device air cooler , Cold intercooler greater than 120 ℃ low-temperature heat of about 570 million kcal / h, used to heat power boiler feed water and in the winter supply of mining water heating and heating of three workshops in the factory, making the device to heat 3 ~ 40,000 kcal / tonne, reducing energy consumption by about 15,000 kcal / tonne throughout the year.
