The level of energy consumption is an integrated oil refinery economics and important indicator of the level of process technology, how to reduce the energy consumption of atmospheric and vacuum distillation unit refinery energy conservation has become a top priority. Atmospheric and vacuum distillation unit energy consumption can be achieved through a variety of ways. With the continuous development of energy conservation, demand lower and lower exhaust gas temperature furnace. But often in the steel pipe waste heat recovery equipment, heat exchangers and other heat transfer surface will produce strong low-temperature dew point corrosion. As so, we focus on is the furnace flue gas waste heat recovery technological applications, and discuss how to prevent low-temperature dew point corrosion, as well as the effect of waste heat recovery.
