Sättet enligt FIGl arbetar på följande sätt: Naturgas (16) törvärmd (18) med varmvatten från varmvattenskrubbern (4), tillföres i önskat flöde gastwbinens (1) brännkarmnare (13) där ett till gasturbinen anpassat tryck (30 bar) upprätthåller).

Oxygen (17) (OZ content suitably> 85%, preferably> 92%), fi- adjusted in a conventional manner by distillation of air in a separate plant '(2) and mixed (18) in other ways as the natural gas, is supplied (l3) in some overstöchiometric fl fate in relation to fl the fate of natural gas. To (13) the exhaust gas vapor production side n of the gas nubin fl) connect the steam generator (3) at the same time as a partial feed of the exhaust gas n from the steam generator after compression in the gas turbine compressor (s) (1 1/12) under temperature control by direct or indirect cooling. To avoid too high local dry-burning temperatures, the oxygen gas is suitably mixed with the gas from the high-pressure compressor (12), whereby the fl of the exhaust gas and the oxygen gas are adapted so that the gas flowing out of the combustion chamber has a temperature adapted to the gas turbine (1237 °).
Efter expansion i gasturbinens (1) hög- och lågnyckssteg (14/15) har avgasen från lågtryckswrbmen (14) något över atmostärsuyck och en temperatur på 4-40°. Gasen bfingas attströmma genom en ånggenemtor (3), varvid dess temperatur sänkes till 120° under generering av högtrycksånga med 400° temperatur och 30 bars tryck (alternativt 550° och 200 bar vid industrimrbm enligt FIGZ). Matarvattnet till ånggenetator (3) avgrenas fi-ån varmvattnet producerat i varnrvattenslcrubbem (4) och har en temperatur på 94°. Änggenerator (3) är av modnfir konstruktion med vänneömringyta av fentuber och med naturlig eller forcerad cirkulation dvs av samma typ som vanligen användes i samband med kombicykel med kondensångcykel.After expansion in the high and low pressure stages (14/15) of the gas turbine (1), the exhaust gas from the low pressure chamber (14) has a slightly above atmospheric pressure and a temperature of 4-40 °. The gas is forced to flow through a steam sensor (3), its temperature being lowered to 120 ° while generating high-pressure steam at 400 ° temperature and 30 bar pressure (alternatively 550 ° and 200 bar at industrial rooms according to FIGZ). The feed water to the steam generator (3) is branched off from the hot water produced in the hot water scrubber (4) and has a temperature of 94 °. Meadow generator (3) is of a modern construction with a friendly ring surface of fentubes and with natural or forced circulation, ie of the same type that is usually used in connection with a combined cycle with a condensate vapor cycle.

The compressors (11/12) increase the pressure of the gas / steam mixture to 30 bar and the pressurized gas fl is fed to the combustion core (13) of the gas turbine, possibly in mixture with the oxygen required for combustion (17). 96-05-19 the temperature is 40 ° at the incoming 20 ° effluent water from the heat sink (5).

Gasunbirter av indusuityp arbetar vanligen vid lägre tryck och temperatur än flygdefiverade gasturbinenexempelvis 14 ba' och 1190°, men kan utföras med stöne eiïekt än de senare. Avgastempexamren är högre, exempelvis 590°, vilket innebär att varianten enligt FIG2 är íördelaküg emedan mottrycksmrbinen (7) då arbetar med vassare ångdata, exempelvis 200 bar och 550°.Indusu-type gas burners usually operate at lower pressures and temperatures than gas-fired gas turbines, for example 14 ba 'and 1190 °, but can be made with a grooming effect than the latter. The exhaust temps are higher, for example 590 °, which means that the variant according to FIG. 2 is ideal because the back pressure turbine (7) then works with sharper steam data, for example 200 bar and 550 °.

The carbon dioxide is then pumped down into the oil source, where the oil is partly dissolved and made to have a lighter surface. In this way, additional large quantities are extracted from non-hazardous sources.
I utföringsexemplet enligt FIGI uppnås vid förbränning av naturgas med syrgas och uppfinningssättets kombination av apparatenheter inklusive separat syrgasverk en total- verkningsgrad el/bränsle på 55% varvid avgasen fiån vannvattenskrubbern (4) utgöres av fuktig koldioxidgas, som kan utnyttjas för framställning av (flytande) koldioxid medan varmvattenöverskottet fi-ån skrubbem (4) är användbart för bl a uppvämmings- ändamål. Sättets nettaverkningsgrad efter avdrag för elenergi-ñrbrulmingen för produktion i särskild anläggning av flytande koldioxid (ca 0,2 kWh/kg koldioxid) blir 50%.

The net efficiency of the method after deduction of the electrical energy roar for production in a special plant of liquid carbon dioxide (approx. 0.2 kWh / kg carbon dioxide) will be 50%. The method according to the invention advantageously allows the use in addition to natural gas, all-gas-shaped fuels maintained by gasification with oxygen-carbonated fuels, for example fossil fuels such as carbon and oil and biomass.
Flytande koldioxid kan deponeras i oceanemas djup, uttjänta olje- och gaskällor; akviferer mm. Deponering i kombination med sättet enligt uppfinningen möjliggör således elgenerering på basis av gasformiga finslen utan ökning av atmosfärens koldioxidhalt dvs sättet möjliggör elförsörjnirig på basis av fossila bränslen, som är lika miljövänlig men mer energiefiektiv än elgenereiing på basis av biobränslen.Liquid carbon dioxide can be deposited in the deep, depleted oil and gas sources of the oceans; aquifers etc. Landfilling in combination with the method according to the invention thus enables electricity generation on the basis of gaseous energy without increasing the carbon dioxide content of the atmosphere, ie the method enables electricity supply based on fossil fuels, which is just as environmentally friendly but more energy efficient than electricity generation based on biofuels.
