| Abstract: | When the feedstock of the visbreaking unit in Liaohe Petrochemical Company was changed to vacuum residue of Liaohe Heavy Crude, the overhead system of the fractionator suffered from severe electro-chemical corrosion from HCl-H 2S-HCN-organic acid- H 2O. The pitting corrosion rate of oil/water separator was 3.1 mm/yr and the 12AlMoV air cooler tubes leaked in less than two months' operation. The application of BZH-1 neutralizer, inorganic ammonia BZH-913 oil-soluble corrosion inhibitor in the overhead system has effectively controlled the development of the corrosion. |
