<p>Coke is quenched with water, from tank 7, in quenching container 1 and the resulting quenching vapours at about 700 DEG C pass to separator 2 for preliminary dust removal, thence to a waste heat boiler 3 which superheat extraction produces steam which is stored in container 4 for consumer use. Condensation of the vapour and residual dust precipitation occurs in condenser 5. The condensate passes, by way of filter 6, back to the tank 7 for reuse. Permanent gases from the vapour pass to container 10 from which they move through a sulphur purifier 11 whereafter the resultant hydrogen- containing gas is available for chemical processing or heating. The permanent gas may pass to a purifying arrangement 12 without encountering the container 10, and the quenching vapour, as it passes from the quenching container 1, may pass directly to a gas purifying stage 15. <IMAGE></p> |
