Regeneration tower flooding
Thread Content
I read in some materials that if the rich liquid contains a high amount of hydrocarbons, it may cause flooding in the regeneration tower. Why does the presence of hydrocarbons in the rich liquid leading to its entry into the regeneration tower result in flooding? I don’t quite understand this; could someone with expertise explain the principle? Thank you, points will be given
Hydrocarbons rapidly vaporize upon entering the regeneration tower, causing large volumes of vapor to pass through the trays quickly and leading to tower flooding.
Light hydrocarbons vaporize much more easily than water, resulting in an increased gas phase load inside the tower
Hydrocarbons can cause the amine solution to foam, leading to easy tower flooding
Hydrocarbons can generally be separated from the rich liquid at 50–65°C; once they enter the tower, they cause a sharp increase in the gas load of the tower
