Abstract

L'invention porte sur l'amélioration apportée à une unité de cokéfaction retardée pourvue d'au moins un four à coke (14), ce dernier étant constitué d'une partie intérieure fermée, d'une partie supérieure (34) dotée d'un orifice (36), d'une buse d'évacuation (38) de vapeur surélevée raccordée à l'orifice et d'un déflecteur (40) qui fait dévier les solides et les liquides d'hydrocarbures lourds s'échappant de l'intérieur du four à coke par l'orifice.
