Abstract
Föreliggande uppfinning avser förfarande och arrangemang för att producera kväve från luft. Uppfinningen kännetecknas av att i en förbränningsmotor för väte förbränns tillfört väte och syret i den omgivningsluft som tillförs motorn varvid motorns avgaser väsentligen utgörs av kväve och vattenånga. Gasblandningen kyls varvid vattenångan blir till vatten som avskiljs varvid återstoden huvudsakligen består av kväve som komprimeras och lagras i tank. Om förbränningsmotorn driver en jordbruksmaskin tillförs gasblandningen jorden bakom jordbruksmaskinen.The present invention relates to a method and arrangement for producing nitrogen from air. The invention is characterized by the fact that in an internal combustion engine for hydrogen, added hydrogen and the oxygen in the ambient air supplied to the engine are burned, whereby the engine's exhaust gases essentially consist of nitrogen and water vapor. The gas mixture is cooled whereby the water vapor becomes water which is separated, whereby the remainder mainly consists of nitrogen which is compressed and stored in a tank. If the internal combustion engine drives an agricultural machine, the gas mixture is supplied to the soil behind the agricultural machine.
Description
Metod och anordning för att producera kväve ur luft Luften runt oss består till största delen av kväve cirka 78 procent och syre cirka 21 procent. I luften finns även mycket små mängder av andra gaser uppgående till cirka 1 procent. Kväve har många industriella användningsområden. Ett viktigt område är framställning av ammo- niak som kan användas för produktion av gödsel samt som bränsle i exv. fartygsmotorer. Idag produceras vanligen kväve från luft genom gradvis komprimering och kylning av luften i en process kallad Hampson-Linde. Method and device for producing nitrogen from air The air around us consists mostly of about 78 percent nitrogen and about 21 percent oxygen. There are also very small amounts of other gases in the air amounting to approximately 1 percent. Nitrogen has many industrial uses. An important area is the production of ammonia, which can be used for the production of fertilizer and as fuel in e.g. ship engines. Today, nitrogen is usually produced from air by gradually compressing and cooling the air in a process called Hampson-Linde.
Syftet med föreliggande uppfinning är att producera kväve ur luft enligt en ny och avsevärt mindre kostnadskrävande metod och anordning. The purpose of the present invention is to produce nitrogen from air according to a new and considerably less expensive method and device.
Metoden utförs i en anordning som utgörs av en energiomvandlare, en motor med intern eller extern förbränning, där arbete genereras via omvandling av värme till arbete och där värmen bildas vid förbränning av väte och syre i den omgivningsluft som tillförs energiomvandlaren varvid avgasema väsentligen, till ca: 99%. kan komma att utgöras av kväve och vattenånga vid ett föredraget optimalt väte-luft-blandningsförhållande. The method is carried out in a device consisting of an energy converter, an engine with internal or external combustion, where work is generated via the conversion of heat into work and where the heat is formed by burning hydrogen and oxygen in the ambient air that is supplied to the energy converter, whereby the exhaust gases essentially, to approx. : 99%. may consist of nitrogen and water vapor at a preferred optimum hydrogen-air mixing ratio.
Genom att kyla avgasema kondenseras vattenångan till vatten som i kondenseringsfasen även fångar förekommande partiklar från exv. motorslitage och motorsmörjolja. Efter att vattnet avskilts återstår en gas bestående av kväve och inledningsvis nämnda små mängder av andra gaser. Den från vatten och eventuella föroreningar renade gasen kan enligt känd teknik kom- primeras och kylas för lagring i tank. By cooling the exhaust gases, the water vapor is condensed into water, which in the condensation phase also captures existing particles from e.g. engine wear and engine lubricating oil. After the water is separated, a gas consisting of nitrogen and the initially mentioned small amounts of other gases remains. The gas purified from water and possible impurities can be compressed and cooled according to known technology for storage in a tank.
Genom att nämnda energiomvandlare, exv. en förbränningsmotor, stirlingmotor, ångmaskin eller gasturbin, kännetecknande bringas utföra nyttoarbete som att driva exv. ett elverk eller annan nyttoanordning och att spillvärrne, i form av motorvärmen och avgasvännet, tillvaratas kan totalverkningsgraden bli mycket hög med följden att kostnaden för produktion av kväve blir låg i förhållande till exv. den nämnda processen Hampson-Linde. By said energy converter, e.g. an internal combustion engine, stirling engine, steam engine or gas turbine, typically made to perform useful work such as driving e.g. a power plant or other utility device and that the waste, in the form of the engine heat and exhaust gases, is taken care of, the total efficiency can be very high with the consequence that the cost of producing nitrogen will be low in relation to e.g. the aforementioned Hampson-Linde process.
Skall tilläggas att också bränsleceller är energiomvandlare som förbrukar syre ur omgivnings- luft genom omvandling av väte och syre i en kemisk reaktion, skild från förbränning av väte och syre, till elektricitet samt vattenånga och avskiljer således kväve ur omgivningsluft att kunna tillvaratas likt från för övriga ovan nämnda energiomvandlare även om det skulle res- tera en högre halt av syre än i avgaserna från energiomvandling baserad på förbränning av väte i ett optimalt blandningsförhållande med luft. It should be added that fuel cells are also energy converters that consume oxygen from the ambient air by converting hydrogen and oxygen in a chemical reaction, separate from the combustion of hydrogen and oxygen, into electricity and water vapor and thus separates nitrogen from the ambient air to be used in the same way as for other above-mentioned energy converter even if there would remain a higher content of oxygen than in the exhaust gases from energy conversion based on the combustion of hydrogen in an optimal mixing ratio with air.
Inom jordbruk kan, vid exv. en traktor eller annan jordbruksmaskin med väteförbränningsmo- tor, avgasema efter eventuell kylning och rening i gödslingssyfte ledas ner i jorden bakom fordonet i samband med plöjning, harvning, sådd, skörd eller annat arbete som kompensation för den kväve som frigörs när jord rörs om i samband med nämnda förfaranden. Vid behov av sterilisering av jord kyls inte avgasema innan de förs ned i jorden. Motsvarande kan även ske vid en jordbruksmaskin med bränslecell och elmotor, i stället för förbränningsmotor, för sin förflyttning. In agriculture, e.g. a tractor or other agricultural machine with a hydrogen combustion engine, the exhaust gases after possible cooling and purification for fertilization purposes are led into the soil behind the vehicle in connection with ploughing, harrowing, sowing, harvesting or other work as compensation for the nitrogen released when soil is moved in connection with said procedures. If soil sterilization is required, the exhaust gases are not cooled before they are brought into the soil. The same can also happen with an agricultural machine with a fuel cell and an electric motor, instead of an internal combustion engine, for its movement.
Ytterligare beskrivning i form av figur/figurer och figurbeskrivning/figurbeskrivningar för en fackmans tillämpning av uppfinningen anses inte vara behövlig men kan tillföras om grans- kande patentmyndighet så kräver. Additional description in the form of figure/figures and figure description/figure descriptions for a professional's application of the invention is not considered necessary, but can be added if the examining patent authority so requires.
