Abstract: The problem of the corrosion of air cooler was happened in the depentanizer of the continuous reformer of Liaohe Petrochemical Company. The effect was not good by upgrading the material of air cooler, adding washing line and using common liquid dechlorination agent. The application of PCL-100 liquid dechlorination agent showed that the chloride content of reformate at the outlet of the dechlorinated device reduced to less than 0.5 μg/g. The service life was 10-months, and met the dechlorination requirements of reformate. The corrosion and salt deposition in the depentanizer were basically solved.

Key words: liquid dechlorination agent, reformate, organic chlorine, inorganic chlorine
