Coke deposited in hydrocarbon vapor conduits as the result of hydrocarbon cracking operations is removed from the conduits without interrupting the cracking operation by periodically contacting the coke deposit with a jet of relatively cold high pressure water. The water is jetted against the coke deposit and in an amount sufficient to thermally shock and break up the coke deposit at a pressure in excess of about 5,000 psig. |
