The anti-corrosion and non-anti-corrosion effects on the top condenser of the propylene removal column in petrochemical gas fractionation are different
Thread Content
The following shows a comparison for tubes in the same location on the top of a propane removal column in a petrochemical company’s gas fractionation unit, as well as on the water circulation side of the condenser coil in that same column, after being in use for over 2 years each.
Yes, there is a big difference between preservative-treated and non-preservative-treated ones. From practical comparisons, it is evident that tubes with anti-corrosion treatment suffer significantly less corrosion, have a longer service life, and thus help reduce maintenance and replacement costs. .
