METHOD FOR RETARDING CORROSION AND COKE FORMATION AND DEPOSITION DURING PYROLYTIC HYDROCARBON PROCESSING

摘要

Coke formation and coil corrosion in pyrolysis furnaces (10) is controlled by adding a mixture of Group IA metal salt, a Group IIA metal salt and an aluminum salt to the hydrocarbon feedstock, at the end of the convection stage via an injection line (40).
