PROCESS FOR GENERATING FROM AIR AND HYDROGENEITHER NITROGEN AND'HYDROGEN MIXTURES 0R NITROGEN.
APPLICATION FILED JULY 7. 1920.

LUIGI CASALE, or TERNI, ITALY.
PROCESS FOR GENERATING FROM AIR AND HYDROGEN EITHER NITROGEN AND HYDROGEN MIXTURES OR NITROGEN.
Application filed July 7,
T 0 all whom it may concern Be it known that LUIGI CAsALE, subject of the Kingdom of Italy, residing at Terni, has invented certain new and useful Improvements in Processes for Generating from Air and Hydrogen Either Nitrogen and Hydrogen Mixtures or Nitrogen, of which the following is a specification.
The present invention relates to an industrial process for generating either nitrogen and hydrogen mixtures or nitrogen free from ox gen. y
The 0 ect of this process is to prepare either nitrogen and hydrogen mixtures or nitrogen free from oxygen, said mixtures and said nitrogen being designed for use in the production of industrial chemical products, as ammonia (N11 nitrid of silicon and similars.
To this efiect the process includes the burning of air in an atmosphere of hydrogen.
The device designed to perform the 'process essentially comprehends a combustion space,.the atmosphere of which is fed by a current of hydrogen proceeding from a suitable reservoir,- while the atmospheric air flows from a nozzle disposed in said space and is furnished by apipe having a regulating valve or cock.
The air combustion is continually effected in the mentioned space in an atmosphere of hydrogen and the products of combustion, which can be either water, hydrogen and nitrogen or water and pure nitrogen, are brought through a cooler or water condenser from which cooler shall flow off both the nitrogen and the quantity of hydrogen not combined in the aforesaid combustion.
In the annexed drawing is represented an example, in a diagrammatical form, of a device designed to perform the process which forms the subject of the present invention.-
In the drawing illustrating anapparatus', 1 is a cylindrical chamber in which terminates the pipe 2 proceeding from the hydrogen reservoir, not shown in the, drawing; 3 is a valve or cook designed to regulate the hydrogen flow through the pipe 2; 4 is a pipe for supplying atmospheric air, which pipe 4 is provided with the regulating cock 5, connected at 5 to the pipe 2 and having Specification of Letters Patent.
Patented July 12, 1921. 1920. Serial No. 394,474.
its inner end coaxial with the pipe 2 in such a manner as to form with the same an annular space for the hydrogen and a cylindrical space concentric to it for the air, both spaces ending in a burner 2.
From the cover 6 of the cylindrical chamber 1 leads a pipe 7 which communicates with the cooler 8. Said cooler is formed by a number of pipes 9 extending through two tight cross plates 10, 10'.
Thewater of condensation collects in the spaces 11, 11 under the plate 10 and the cooling water circulates around the pipes 9 of the cylinder 8, between the nozzles 12, 13, which, for instance, can be connected to public water supply. 16 is an aspirator driven by any suitable motor, which is connected by a pine 17-18 to the cooler (chamber 11") While the outlet pipe 19 is connected through the pipe 20 to a suitable reservoir adapted to receive the resultant product either of nitrogen or of hydrogen-nitrogen mixture;
The device works in the. following manner: When the cock 3 is opened and the aspirator. 16 is started, a partial vacuum is created in the pipes 9, in the pipe 7 and in the cylindrical chamber 1, facilitating the flow of a current of hydrogen through the whole system in which the air is replaced by hydrogen.
By altering the opening of the cock 5, the quantity of air in respect to the hydrogen can be regulated and varied proportions in nitrogen-hydrogen mixtures can be obtained, or, if desired, pure nitrogen can be obtained when the introduced quantity of air is such that the oxygen contained by it shall be sufficient to combine with the existing hydrogen.
'In order to start the combustion a suitable sparking device may obviously be placed in juxtaposition to the Burner 2 in such a manner as to excite a spark designed to initiate the process of air combustion. The process afterward proceeds automatically in a continuous manner. Y
The residues .of combustion, consisting either of pure nitrogen or mixtures in any predetermined proportions of nitrogen and hydrogen, are drawn from the combustion chamber through the cooler by means of the aspirator 16 and the water condensed in the cooler flows into the reservoir or collecting tank 23 through' the pipes 22.
The apparatus illustrated may be employed but is merely illustrative of means for the process and is susceptible to all the modifications advised by experience, retaining as abasis the principle of burning the air oxygen in a hydrogen atmosphere.
It can be, for instance, in some cases convenient to cause the hydrogen and the air to flow in the combustion chamber through separated pipes, suitable flow regulators or cocks being obvious in said pipes. It is obvious that air is fed to the combustion chamber 1 at about normal atmospheric pressure.
Itis understood that combustion is started in the hydrogenatmosphere as soon as the combustion chamber is filled with'hydrogen and atmospheric air is admitted to the combustionchamber so that the in-rushing current of air will be fed into an atmosphere of hydrogen and that a supply of hydrogen in proportion to the volume of alr,
place, as distinguished from a mixture of hydrogen and air formed before combustion takes place. The union of the hydrogen with the oxygen of the air takes place without a previous mixing of the hydrogen and What I claim is: v
