demluk: You might expect to see corrosion at the top of the tower if the vapors are condensing in the tower. Also, corrosion of the reflux line and at the inlet to the tower from the line. Hope this helps! David Hendrix The Hendrix Group Inc.

Demluk: Assuming that the regenerator tower was carbon steel, the corrosion would probably be as a combination of general corrosion and pitting. Re your oil pipeline, the corrosion would most probably be at the bottom of the pipeline under deposits (similar to the BP Alaska pipeline). Re your CO2 pipe, corrosion rates of carbon steel would be expected to be high. It is difficult to predict the corrosion location and type, (i.e., pitting, mesa, general, etc.) without conducting a detailed risk analysis, based on pipeline topography.
