我厂常减压—催化裂化联合装置,自77年起,共实现十余项节能措施,节油1947公斤/时,节汽18.9吨/时,节电192度/时,合计节能3482万千卡/时。两套装置总能耗由58.3万千卡/吨,下降到47.7万千卡/吨,其中,常减压装置由28.1万千卡/吨,下降到24.4万千卡/吨,催亿裂化装置由111万千卡/吨,下降到103万千卡/吨。79年共节油6,000吨,节汽13,000吨,节电320万度。我们采取以下几项主要措施。一、提高加热炉效率 I plant atmospheric decompression - catalytic cracking unit, since 77 years, a total of more than 10 items to achieve energy-saving measures, saving 1947 kg / h, section steam 18.9 tons / hour, saving 192 degrees / hour, total energy savings of 34.82 million Card / hour. The total energy consumption of the two sets of equipment dropped from 583,000 kcal / tonne to 477,000 kcal / tonne, of which the atmospheric and vacuum unit dropped from 281,000 kcal / tonne to 244,000 kcal / tonne, From 111 million kcal / ton, down to 103 million kcal / ton. 79 years a total of 6,000 tons fuel-efficient, saving 13,000 tons, saving 3.2 million degrees. We take the following major measures. First, improve the heating furnace efficiency
