我厂原设计年处理量250万吨,由于原油不足,一直处于低处理量状态操作。常减压装置原设计二台加热炉,总热负荷为5700万大卡/时,实际使用热负荷只有2300万大卡/时,占原设计的40.4%,历年来加热炉上能源浪费很大,而且操作比较困难。特别是80年装置搞了低热能回收措施以后,原油经充分换热,进加热炉的温度显著提高,使常压炉操作负荷更为降低。为了进一步搞好节能工作,我们对常压加热炉进行了改造:封闭常
Our original design annual capacity of 2.5 million tons of crude oil, due to lack of crude oil, has been in low-volume state operation. Atmospheric and vacuum distillation unit was originally designed two heating furnace, the total heat load of 57 million kcal / hour, the actual use of heat load of only 23 million kcal / hour, accounting for 40.4% of the original design, the furnace over the years a lot of energy waste , And the operation is more difficult. In particular, after 80 years of installation of low heat energy recovery measures, the crude oil is fully heat-exchanged and the temperature of the reheating furnace is significantly increased, so that the operating load of the atmospheric pressure furnace is further reduced. In order to further improve the energy-saving work, we carried out the transformation of atmospheric furnace: closed often
