METODO PARA REDUCIR EL USO DE ANTIESPUMANTE DE SILICONA EN PROCESOS DE COQUIZACION RETARDADA

摘要

The current invention provides an improved petroleum coking process wherein the risk of silicone poisoning of units downstream of the coke drums is reduced. The method of the current invention controls the foam layer within the coke drum by injection of a silicone anti-foam agent in a highly aromatic carrier fluid such as slurry oil.
