Will the cold reflux at the top of an atmospheric pressure column have an impact on tower corrosion?
Thread Content
The top of the atmospheric pressure column is controlled in terms of temperature using cold reflux; the temperature of this cold reflux is around 35–50, while the top temperature is kept at around 135–140. Recently, the corrosion rate at the column top has been above the acceptable level.
