Description
Oppfinnelsen vedrorer en brenneranordning for forbrenning av overskudd av gass som kommer fra anlegg for separering av denne fra olje og kondensat, som inneholdes i gassen, omfattende midler for å fore fraseparert brennbar gass gjennom to forskjellige kanaler under to ulike trykk, samt et matekammer forsynt med justerbart luftinntak; en hoytrykksinjektor slik tilkoblet at den innforer brennbar gass fra den kanal som forer gass med det hbyeste av de to trykk inn i matekammeret og derved suger luft inn i dette gjennom luftinntaket; midler for å innfore brennbar gass fra den andre av nevnte kanaler i matekammeret på The invention relates to a burner device for burning excess gas coming from facilities for separating it from oil and condensate, which is contained in the gas, comprising means for passing separated combustible gas through two different channels under two different pressures, as well as a feed chamber provided with adjustable air intake; a high-pressure injector connected in such a way that it introduces flammable gas from the channel that feeds gas with the higher of the two pressures into the feed chamber and thereby sucks air into it through the air intake; means for introducing combustible gas from the second of said channels into the feed chamber on
et sted nær injektorens ovre ende; et blandekammer som mottar brennbar gass og luft fra matekammeret og som danner en gass-stromningspassasje, som divergerer mot den ende som ligger bort fra matekammeret, og en brenner som mates fra nevnte divergerende passasje, hvilken brenner er forsynt med midler for antennelse av den brennbare gass. somewhere near the upper end of the injector; a mixing chamber receiving combustible gas and air from the feed chamber and forming a gas flow passage diverging towards the end away from the feed chamber, and a burner fed from said diverging passage, which burner is provided with means for igniting the combustible gas.
Problemet med å bli kvitt slike gasser oppstår forst ved prøve-boringer, enten det dreier seg om oljehull eller gasshull, derpå ved produksjonsfeltene og endelig ved behandlings- og raffinerings-anleggene. The problem of getting rid of such gases first arises during test drilling, whether it is an oil hole or a gas hole, then at the production fields and finally at the processing and refining facilities.
Ved produksjonsfeltene for olje er det fast praksis ved hjelp av brennere å brenne den gass som avgis fra separatorer og som av mange grunner ikke kan bli gjenstand for kommersiell utnyttelse, idet hovedårsakene ligger i den geografiske beliggenhet. At the production fields for oil, it is standard practice to use burners to burn the gas emitted from separators which for many reasons cannot be the subject of commercial exploitation, the main reasons being the geographical location.
Gass ledes vanligvis fra hbytrykks- og lavtrykks-separatorer til forskjellige brennere. Forbrenningen er alltid meget ufullstendig, idet tilfbrselen av oksygen er utilstrekkelig til at den kan finne sted ved diffusjon omkring flammen. Herav folger en konstant ut-sendelse av svart rok og nedfall av uforbrente stoffer enten i form av kulIpartikler eller dråper av hydrokarbonforbindelser som blir kondensert under påvirkning av det plutselige trykkfall. Selve flammen er sterkt strålende og lysende. Gas is usually routed from high-pressure and low-pressure separators to different burners. Combustion is always very incomplete, as the supply of oxygen is insufficient for it to take place by diffusion around the flame. This results in a constant emission of black smoke and precipitation of unburnt substances either in the form of coal particles or droplets of hydrocarbon compounds which are condensed under the influence of the sudden drop in pressure. The flame itself is intensely brilliant and luminous.
Når videre gasskilden er under hbyt trykk, for eksempel flere deka-bar, blir den avkjbling som folger med trykkfallet så stor at dannelsen av hydrater kan forårsake tilstopning av brennerledningen. Furthermore, when the gas source is under high pressure, for example several deka-bar, the decoupling that follows with the pressure drop becomes so great that the formation of hydrates can cause clogging of the burner line.
Den forurensende virkning av slike anlegg er stor og manifesterer seg ved å være meget synlig, hvilken også kan ha psykologiske kon-sekvenser som endog kan være betydeligere enn den reelle virkning. The polluting effect of such facilities is great and manifests itself by being very visible, which can also have psychological consequences which can even be more significant than the real effect.
Anordningen ifblge oppfinnelsen sbker å eliminere disse ulemper ved å mate brennerne med en blanding av gass og luft i forhold som bevirker fullstendig forbrenning og praktisk talt gjor overflbdig oppvarmning ved stråling og ikke tillater dannelsen av hydrater. The device according to the invention seeks to eliminate these disadvantages by feeding the burners with a mixture of gas and air in conditions which effect complete combustion and practically cause excess heating by radiation and do not allow the formation of hydrates.
Brenneranordningen ifblge oppfinnelsen kjennetegnes ved at hoytrykksinjektoreri er forsynt med midler for justering av beliggenheten av injektorens utlopsende i forhold til overgangen - mellom matekammeret og blandekammeret. The burner device according to the invention is characterized by the fact that the high-pressure injector is provided with means for adjusting the location of the injector outlet in relation to the transition - between the feed chamber and the mixing chamber.
Ifblge en foretrukket utformning er det foran den divergerende péssasje anordnet en konvergerende passasje i blandekammeret direkte kommuniserende med matekammeret. According to a preferred design, a converging passage is arranged in front of the diverging passage in the mixing chamber directly communicating with the feed chamber.
Oppfinnelsen vil forstås bedre ved hjelp av nedenstående ikke be-grensende beskrivelse åv et utfbrelseseksempel vist på tegningen. The invention will be better understood with the help of the following non-limiting description of an exemplary embodiment shown in the drawing.
Under henvisning til tegningen finnes det på et produksjonsfelt separasjonsmidler for olje eller kondensat og gass,, bestående av en hbytrykks-separator 1 matet fra et borehull eller en oppsamler (ikke vist), som avgir hbytrykks-gass 2 og ufullstendig avgasset væske 3. Denne væske tilfores en lavtrykks-separator 4 som avgir lavtrykks-gass 5 og olje eller kondensat 6. With reference to the drawing, there are oil or condensate and gas separators in a production field, consisting of a high-pressure separator 1 fed from a borehole or a collector (not shown), which emits high-pressure gas 2 and incompletely degassed liquid 3. This liquid is fed to a low-pressure separator 4 which emits low-pressure gas 5 and oil or condensate 6.
Brenneranordningen er festet på en bærer 7, bestående av for eksempel en oppbygning av profiler med tverrbjelker og stag, og omfatter nbdvendige festemidler for tilfbrselsledningene for hbytrykks-gass 9 såvel som for de (ikke viste) elektriske kabler for tenning og styring av forbrenningen..The burner device is attached to a carrier 7, consisting for example of a structure of profiles with cross beams and struts, and includes the necessary fasteners for the supply lines for high-pressure gas 9 as well as for the (not shown) electrical cables for ignition and control of the combustion.
Matekammeret lo omfatter regulerbare luftinntak 11, et inntak for brennbar gass 12 avgitt fra lavtrykks-separatoren foran injektoren for brennbar gass 13 avgitt fra hbytrykks-separatoren, idet injektoren 13 er plassert i aksen for et blandekammer 14 som ligger umid-delbart inntil matekammeret og omfatter en konvergerende del 15 fulgt av en divergerende del 16. Injektoråpningens (injektor 13) stilling i forhold til inntaksplanet i blandekammeret kan reguleres langs dettes akse. Valg av denne injektoråpnings stilling utgjor et av reguleringsmidlene for luftkonsentrasjon i den gass som be-handles i blandekammeret. Ved enden av den divergerende del 16 befinner seg et munnstykke 17 som munner ut i fri luft med et inn-skutt gitter é.l. 18 som hindrer tilbakeslag av flammen. På munn-stykket 17 er anbrakt ikke viste anordninger for tenning og styring av flammen. The feed chamber lo comprises adjustable air intakes 11, an intake for combustible gas 12 emitted from the low-pressure separator in front of the injector for combustible gas 13 emitted from the high-pressure separator, the injector 13 being placed in the axis of a mixing chamber 14 which lies immediately next to the feed chamber and comprises a converging part 15 followed by a diverging part 16. The position of the injector opening (injector 13) in relation to the intake plane in the mixing chamber can be regulated along its axis. Selection of this injector opening position constitutes one of the regulating means for air concentration in the gas that is treated in the mixing chamber. At the end of the diverging part 16, there is a nozzle 17 which opens into the open air with an inserted grid etc. 18 which prevents flashback of the flame. Devices (not shown) for lighting and controlling the flame are placed on the nozzle 17.
Denne brenneranordning vil gi en fullstendig forbrenning av en gass-blanding. Flammen blir av denne grunn gjennomsiktig og lite strålende, de avgitte forbrenningsgasser er nbytrale, ikke forurensende, og de inneholder ikke uforbrente produkter i form av faste stoffer eller væske. Videre hindrer iblandingen i.luft, tilfort ved om-givelsestemperatur, i de ved tenningen avkjblte brennbare gasser en for sterk avkjbling, som ville bevirke dannelse av mulige hydrater. This burner device will provide a complete combustion of a gas mixture. For this reason, the flame becomes transparent and not radiant, the emitted combustion gases are neutral, not polluting, and they do not contain unburned products in the form of solids or liquids. Furthermore, the mixing of air, supplied at ambient temperature, in the combustible gases cooled during ignition prevents a too strong cooling, which would result in the formation of possible hydrates.
Drift av brenneranordningen krever ingen tilfbrsel av energi. Den luft som er nbdvendig for forbrenningen tilfores ved atmosfærisk induksjon ved hjelp av en injektor som for å utfore dette bruker en del av energien i hbytrykks-gassen. Når anordningen mates med gass-residier i et raffineri, kan man måtte ta i betraktning enten tilfbrsel av hbytrykks-brennbar gass eller tilfbrsel av en energi-mengde tilstrekkelig til å medbringe de nbdvendige mengder luft for forbrenning av gass som vanligvis består av tunge produkter og avgis under forholdsvis lavt trykk. Operation of the burner device requires no input of energy. The air required for combustion is supplied by atmospheric induction with the help of an injector which, in order to do this, uses part of the energy in the high-pressure gas. When the device is fed with gas residues in a refinery, one may have to take into account either the supply of high-pressure combustible gas or the supply of an amount of energy sufficient to carry the necessary quantities of air for the combustion of gas which usually consists of heavy products and emitted under relatively low pressure.
