Abstract
206,822. Soc. l'Oxhydrique Franþaise. Nov. 7, 1922, [Convention date]. Hydrogen.-In the manufacture of hydrogen by the iron-steam process the reducing gas required for regenerating the metal is heated by the waste of blast furnaces, gas works, coke ovens, metallurgical plant and like installations from which the reducing gas itself may be obtained, the hot excess reducing gases being utilized in the burners of the installation or returned to the gas main. In an example coke oven gases required for the reduction are heated by passing them through brick heat recuperators in which the reducing apparatus is situated. Burnt gases after heating the ovens pass through the iron oxide and finally give up their heat to the usual brick piles of the recuperators. The coke oven gas preheated in the recuperators passes on to the reducing apparatus containing the hot iron oxide, the issuing gas containing the excess reducing gases being employed in any part of the plant. In a second example coal gas to be used for the reduction after the recovery of bye-products and de-sulphurization, is preheated in the dampers in which the drawn coke is extinguished. In a third example the reducing gas is produced independently of the cokeovens, gas works, metallurgical plant &c., but is heated by the waste heat of the latter.
