When tower flooding occurs, results of field diagnoses of the problem must be included in the solution to the flooding problem.
Results of the dianosis can help determine the easiest means to eliminate the flooding. Two examples indicate how good field diagnosis could have led to simpler solutions to tower-flooding problems.
One refiner was experiencing flooding of a depropanizer. Based on field investigation, it was determined that flooding was caused by corrosion products in the depropanizer feed.
Particulates from corrosion promoted foaming...
