Question: What are some possible causes of corrosion in line of heavy naptha from crude tower?
Keywords: v1i3,corrosion,heavy,naphthas,column
Answer: Some possibilities could include:1. water trapped in the line due to a deadleg or low spot which can not drain.2. if processing high naphthenic acid crudes, perhaps the neutralization number is high in the heavy naphtha fraction, although this would be unusual. Test the stream neutralization number.3. stream temperature too cool and condensing salts out in the line.
