Application of heat exchanger network software package, the second regular decompression heat exchanger network in Jilin refinery energy saving research, to identify the existing problems of the heat exchanger network, through the heat exchanger network synthesis, analysis, heat exchanger Optimize the design and process simulation, put forward the optimization and improvement of the original heat exchanger network, and optimized the design of the heat exchanger network after the initial base oil exchange temperature from the original 30 2 ℃ to 32 2 ℃, 2 During the overhaul in May 2000, it was successfully transformed and drove, and the device was technically calibrated in June 2000. All the indexes reached the designed values, saving 4918 tons of fuel oil annually and saving energy 6 880000 yuan, 1500000 yuan investment in equipment, transformation investment recovery period of 2.6 months, considerable energy-saving benefits.
