除了前面谈到多次进行换热流程调整,换热充分,提高原油入炉温度减少炉用燃料之外,还采用了以下措施:1.低压瓦斯回收做减压炉燃料七○年大检修后,将容002低压瓦斯由向大气放空改为减压炉做燃料。①基本数据原油处理量为417吨/时,低压瓦斯量为560标米~3/时,低发热值为12060大卡/标米~3/,瓦斯压力为0.2Kg/cm~2。②节约燃料油按上面所提供的基本数据核算,每年可节约燃料油5600吨。
In addition to the foregoing talked about several times to adjust the heat exchange process, full heat exchange, increase the temperature of crude oil into the furnace to reduce the furnace fuel, but also used the following measures: 1.Low pressure gas recovery to do decompression furnace fuel 70 years after major overhaul , 002 low-pressure gas will be replaced by the vacuum to the vacuum furnace fuels. ① Basic data The crude oil handling capacity is 417 tons / hour, the low pressure gas amount is 560-3.3 meters, the low heating value is 12,060 kcal / m3, and the gas pressure is 0.2Kg / cm2. ② save fuel oil According to the basic data provided above, annual savings of 5,600 tons of fuel oil.
