Study on the Dew Point Corrosion Mechanism of Atmospheric and Vacuum Distillation Unit Low-Temperature Part

In view of dew point corrosion for the emergence of low-temperature part of atmospheric and vacuum distillation unit, from the analysis of the main factors for the impact of dew-point temperature,we make the calculation of the dew-point temperature and composition of the liquid .And it is calculated through the examples of calculation steps. We can get a different component content will lead to the different dew point temperature, when the dew point temperature changes, the liquid component of the dew-point percentage and the position with the corresponding change.
