Abstract

A process and apparatus for the dry cooling of coke involves the provision of a vessel having therein first and second zones in full communication with each other. Hot coke from a coking operation is introduced into the first zone and is passed through the first and second zones. Raw coke oven gas from the coking operation is introduced into the first zone, thereby reducing the temperature of the coke, while cleaning the raw coke oven gas to form cleaned coke oven gas. The cleaned coke oven gas is removed from the first zone, cooled, and then directly or indirectly utilized as a heat carrier gas introduced into the second zone to therein further reduce the temperature of the coke. The thereby further cooled coke is removed from the second zone.
