Description
Oppfinnelsen vedrorer et neddykket undervannsanlegg for å eliminere forbrenningsgasser under trykk som avgår fra olje- og gasseparerende anordninger i forbindelse med hydrokarbonproduk-sjonsbrdnner, hvilket anlegg omfatter i det minste én neddykket og vanntett brenner bestående av i det minste ett matekammer for en brennbar gassblanding, hvilket matekammer er omsluttet av et forbrenningskammer forsynt med antennelsesmidler for å initiere forbrenning inne i nevnte forbrenningskammer; i det minste ett brennermateror, hvis ene ende forer til fri luft, mens den andre ende er forbundet med matekammeret for brenneren ved hjelp av en divergerende passasje; i det minste én injektor som er tilkoblet for å motta brennbar gass under trykk fra en separeringsanordning og forlopende inne i brennermateroret oppstroms for den divergerende passasje; i det minste én avlopskanal forbundet med forbrenningskammeret for brenneren og forende til fri luft, samt midler for å justere strommen av brennbar gass gjennom injektoren til brennermateroret. The invention relates to a submerged underwater plant for eliminating combustion gases under pressure from oil and gas separating devices in connection with hydrocarbon production plants, which plant comprises at least one submerged and watertight burner consisting of at least one feed chamber for a combustible gas mixture, which feed chamber is enclosed by a combustion chamber provided with ignition means to initiate combustion within said combustion chamber; at least one burner feed pipe, one end of which leads to free air, while the other end is connected to the feed chamber of the burner by means of a divergent passage; at least one injector connected to receive combustible gas under pressure from a separator and extending inside the burner feed pipe upstream of the divergent passage; at least one exhaust channel connected to the combustion chamber of the burner and leading to free air, and means for adjusting the flow of combustible gas through the injector to the burner feed pipe.
Slik undervannsforbrenning av gass som opptrer i forbindelse med flytende hydrokarbonfprbindelser, er aktuell når gassen som tilveiebringes ikke kan utnyttes kommersielt. Disse natur-gasser frembringes under provedrift såvel som under produksjonen. De separeres fra oljen ved borehullene og/eller lagringssentrene og blir vanligvis brent som en fakkel. Such underwater combustion of gas that occurs in connection with liquid hydrocarbon compounds is relevant when the gas provided cannot be used commercially. These natural gases are produced during trial operation as well as during production. They are separated from the oil at the wells and/or storage centers and are usually burned as a flare.
Den gassmengde som man således må kvitte seg med kan komme opp The amount of gas that you thus have to get rid of can increase
i flere hundretusen kubikkmeter pr. dag. Volumer på noen titusener kubikkmeter pr. dag kan brennes ved hjelp av brennere installert på produksjonsplattformene. For storre mengder gass blir varmeutviklingen meget sterk, og variasjoner i vindretningen gjor fremgangsmåten farlig for produksjonsanlegget og for per-sonalet. Det blir da tvingende nodvendig å installere brenneren in several hundred thousand cubic meters per day. Volumes of several tens of thousands of cubic meters per day can be burned using burners installed on the production platforms. For large quantities of gas, the heat generation becomes very strong, and variations in the wind direction make the process dangerous for the production plant and for the personnel. It then becomes imperative to install the burner
i noen avstand fra produksjonsplattformen og konstruere en bærer for brenneren, vanligvis i form av en annen plattform-anordning hvis konstruksjonsomkostninger stiger meget raskt med okning av vanndybden. at some distance from the production platform and construct a carrier for the burner, usually in the form of another platform device whose construction costs rise very rapidly with increasing water depth.
Kan gassen ikke brukes på feltet og heller ikke samles opp for transport, blir den vanligvis innblåst i havvannet, idet man regner med en mere effektiv dispersjon enn ved ganske enkelt å sende gassen ut i atmosfæren, samtidig som det fåes en viss opplosning i havvannet. Denne fremgangsmåten kan imidlertid være direkte farlig, idet den i stille vær bevirker at der dannes sjikt av eksplosiv gassblanding, samtidig som havvannet forurenses. If the gas cannot be used in the field, nor collected for transport, it is usually blown into the seawater, since a more effective dispersion is expected than by simply sending the gas out into the atmosphere, while at the same time a certain amount of dissolution in the seawater is obtained. However, this method can be downright dangerous, as it causes a layer of explosive gas mixture to form in calm weather, and at the same time pollutes the sea water.
En annen fremgangsmåte består i å fortynne de gassformige hydro-karbonf or bindelser i luften ved hjelp av en blanderanordning og så å sende opp i atmosfæren en ikke-brennbar blanding. Denne metode utelukker risiko for eksplosjon, men medforer bruk av omfattende materiale med betydelig energiforbruk, og krever okning av produksjonsplattformenes storrelse, samt forsterkning av disse, hvis man da ikke går til bygging av en separat plattform. Ved denne metode foreligger forovrig fremdeles risiko for forurensning av atmosfæren, særlig når gassen omfatter en betydelig andel av tunge hydrokarbonforbindelser. Når mengden av gassformige hydrokarbonforbindelser i atmosfæren er mindre enn 3%, er<*> risiko for eksplosjon praktisk talt lik null, men derimot bor forgiftningsterskeien tas i betraktning, idet denne er 0,2% for propan og 0,05% for pent an, hexan og héptan. Another method consists in diluting the gaseous hydrocarbon compounds in the air using a mixing device and then sending a non-combustible mixture into the atmosphere. This method excludes the risk of explosion, but entails the use of extensive material with significant energy consumption, and requires an increase in the size of the production platforms, as well as their reinforcement, if one does not then go to the construction of a separate platform. With this method, there is still a risk of contamination of the atmosphere, particularly when the gas comprises a significant proportion of heavy hydrocarbon compounds. When the amount of gaseous hydrocarbon compounds in the atmosphere is less than 3%, the risk of explosion is practically zero, but on the other hand the poisoning threshold must be taken into account, as this is 0.2% for propane and 0.05% for pent an , hexane and heptane.
Anordningen for undervannsforbrenning ifblge oppfinnelsen tar hensyn til disse problemer, idet den unngår fri avgivelse av betydelige gassmengder uansett produksjonsplattformens forhold, og uten å medfore fare for anlegg eller personell. Dette opp-nås for et anlegg av det slag som er angitt i innledningen ved at det nevnte matekammer og forbrenningskammeret kommuniserer med hverandre ved hjelp av en rekke åpninger. The device for underwater combustion according to the invention takes these problems into account, as it avoids the free release of significant quantities of gas regardless of the conditions of the production platform, and without causing danger to facilities or personnel. This is achieved for a plant of the type indicated in the introduction by the said feed chamber and the combustion chamber communicating with each other by means of a series of openings.
Oppfinnelsens hovedtrekk såvel som en rekke ytterligere trekk The main features of the invention as well as a number of additional features
og detaljer vil fremgå avden efterfolgende beskrivelse og av tegningene, hvor and details will appear from the following description and from the drawings, where
Fig. 1 viser skjematisk anordning i et undervannsområde som kan være i salt- eller ferskvann, av en produksjonsplattform 1 for hydrokarbonforbindelser, på hvilken plattform det, ved Fig. 1 shows a schematic arrangement in an underwater area that can be in salt or fresh water, of a production platform 1 for hydrocarbon compounds, on which platform, at
siden av bronnhodene og oppsamlingsanlegget (ikke vist), be-finner seg et prosessanlegg omfattende en hoytrykksseparator 2 med et hoytrykksgassuttak 3 og et uttak 4 for ufullstendig side of the well heads and the collection facility (not shown), there is a process facility comprising a high-pressure separator 2 with a high-pressure gas outlet 3 and an outlet 4 for incomplete
avgasset olje samt en lavtrykksseparator 5 med et lavtrykks-gassuttak 6 og et uttak 7 for lagringsolje. degassed oil as well as a low-pressure separator 5 with a low-pressure gas outlet 6 and an outlet 7 for storage oil.
Undervanns-forbrenningsanlegget er festet til en bærer 8 på plattformen 1. En stort sett vertikal matekanal 9 er i den ovre ende forbundet med fri luft gjennom en åpning 10. I denne kanal munner suksessivt ut forst i liten avstand fra åpningen lo, en tilforselsledning 11 for luft som avgis fra en hjelpe-startvifte 12, og så en ledning 13 for tilforsel av den gass som avgis fra lavtrykks-separatoren 5. I den nedre ende har kanalen en blandesone 14 som omfatter to deler, en ovre konvergerende del 15 og derpå folgende divergerende del 16. Ved innlopet til den konvergerende del og i dennes akse er det anordnet et injeksjonsror 17 for den gass som avgis fra hoy-trykks-separatoren 2. Denne injektors posisjon er regulerbar langs kanalens akse. The underwater incinerator is attached to a carrier 8 on the platform 1. A largely vertical feed channel 9 is connected at the upper end to free air through an opening 10. In this channel, a supply line 11 successively exits first at a short distance from the opening lo for air emitted from an auxiliary starting fan 12, and then a line 13 for supplying the gas emitted from the low-pressure separator 5. At the lower end, the channel has a mixing zone 14 comprising two parts, an upper converging part 15 and then following divergent part 16. At the inlet to the converging part and in its axis, an injection rudder 17 is arranged for the gas emitted from the high-pressure separator 2. The position of this injector is adjustable along the axis of the channel.
Matekanalen 9 munner nedentil ut i et matekammer 18 for en brenner 19, hvilken brenner videre omfatter et forbrenningskammer 20 utenfor matekammeret, fra hvilket det er adskilt av en vegg 21, perforert av flere åpninger 22. The feed channel 9 opens below into a feed chamber 18 for a burner 19, which burner further comprises a combustion chamber 20 outside the feed chamber, from which it is separated by a wall 21, perforated by several openings 22.
Forbrenningskammeret 20 er ved hjelp av ikke viste samle-kanaler forbundet med en utlopskanal til fri luft 23 for forbrent gass. The combustion chamber 20 is connected by means of collecting channels, not shown, to an outlet channel to free air 23 for burnt gas.
Fig. 2 viser et skjema for å illustrere virkemåten av for-brenningsanlegget ifolge fig. 1. Videre er vist et styre- og sikringssenter 24, som mottar indikasjoner fra styreorganene 25 for forbrenningen og sender impulser til ventilene på Fig. 2 shows a diagram to illustrate the operation of the combustion plant according to fig. 1. Furthermore, a control and safety center 24 is shown, which receives indications from the control bodies 25 for the combustion and sends impulses to the valves on
separatorene 26, 27, 28, til hjelpeviften 12 og til tennorganet 29. the separators 26, 27, 28, to the auxiliary fan 12 and to the ignition device 29.
Figurene 3 - 6a viser forskjellige typer av brennere egnet for de forskjellige sammensetninger av gass og for forskjellige forekommende undervannsforhold og alt efter som det arbeides i fersk eller mer eller mindre salt vann og/eller mer eller mindre urolig eller strommende vann. Alle brennerne er imidlertid varianter av den som er definert i beskrivelsen av fig. 1, og omfatter således et matekammer og et forbrenningskammer som kommuniserer innbyrdes ved hjelp av et antall slisser eller åpninger i en mellomliggende skillevegg e.l. Figures 3 - 6a show different types of burners suitable for the different compositions of gas and for different occurring underwater conditions and depending on whether one is working in fresh or more or less salty water and/or more or less turbulent or flowing water. All the burners, however, are variants of the one defined in the description of fig. 1, and thus comprises a feed chamber and a combustion chamber which communicate with each other by means of a number of slots or openings in an intermediate partition wall or the like.
I de forskjellige utforelser ifolge fig. 3,3a, 4,4a,5,5a og 6, 6a har brenneren et ytre hus 19 vanligvis av form som en avkortet kjegle mellom to lett buede ender. Den ovre ende som har storre diameter enn nedre ende, omfatter en aksial mate-åpning 9' forbundet til mateledningen og flere utlop 23 for forbrent gass forbundet til den (ikke viste) oppsamler for forbrent gass. In the various embodiments according to fig. 3, 3a, 4, 4a, 5, 5a and 6, 6a, the burner has an outer housing 19 usually shaped like a truncated cone between two slightly curved ends. The upper end, which has a larger diameter than the lower end, comprises an axial feed opening 9' connected to the feed line and several outlets 23 for burnt gas connected to the (not shown) collector for burnt gas.
I fig. 3 og 3a består skillet mellom mate- og forbrenningskamrene av en sylindervegg 21C med samme akse som brennerens ytre skall 19C, idet denne sylinder utgjores av et sett fliser 31 av ildfast materiale, hvis sammenstøtende kanter 31' danner slisser 22C for brenneren. Flisene 31 er festet til ovre og nedre ende. 1 fig. 4 og 4a består skillet mellom mate- og forbrenningskamrene av et med brennerens ytre skall 19D koaksialt ror 21D som i den ovre og nedre ende er forbundet med skallet. Roret omfatter åpninger 22D som utgjor like mange brennåpninger. Et gitter 32 som hindrer returflamme, er anbragt nær brenner-åpningen. Matekammeret 18D er delt i flere seksjoner ved hjelp av platevegger 33 med åpninger 34 som lar seksjonene kommuni-sere innbyrdes. In fig. 3 and 3a, the separation between the feed and combustion chambers consists of a cylinder wall 21C with the same axis as the burner's outer shell 19C, this cylinder being made up of a set of tiles 31 of refractory material, whose clashing edges 31' form slits 22C for the burner. The tiles 31 are attached to the upper and lower ends. 1 fig. 4 and 4a, the separation between the feed and combustion chambers consists of a rudder 21D coaxial with the burner's outer shell 19D, which is connected to the shell at the upper and lower end. The rudder comprises openings 22D which make up the same number of fire openings. A grid 32 which prevents return flame is placed near the burner opening. The feed chamber 18D is divided into several sections by means of plate walls 33 with openings 34 which allow the sections to communicate with each other.
I fig. 5 og 5a er parallelle ror 35 som er regelmessig fordelt og festet til innerveggen av er ror 36, fort gjennom ende-veggene av matekammeret og er i hver ende åpne utenfor kammeret. In fig. 5 and 5a are parallel rudders 35 which are regularly spaced and attached to the inner wall of rudders 36, fast through the end walls of the feed chamber and are at each end open outside the chamber.
I fig. 6 og 6a består skillet mellom mate- og forbrenningskamrene av et sylindrisk.bur 37 hvis stenger består av parallelle ror 38 som er fort gjennom ovre og nedre ende av brennerens ytre skall 19F, til hvilket de er tettende festet med åpninger utad. Disse ror er anordnet så tett at avstandene mellom dem danner like mange forbrenningsslisser 37F. Denne utformning er spesielt egnet til bruk i anlegg som er utsatt for store variasjoner i de avgitte mengder , idet nemlig flammeområdet varierer med den avgitte gassmengde. I den viste utformning består buret av ror med sirkulært tverrsnitt, men forskjellige former av tverrsnittet kan velges alt efter de spesielle forbrenningsproblemer som må loses. Ror med ovalt tverrsnitt eller bestående av en ringseksjon begrenset av to sammenfoyningskurver, fortrinnsvis i form av en sirkel-bue, kan med fordel anvendes når man må regne med en reduksjon av antall forbrenningsslisser. Andre Ibsninger omfatter flere ror for sirkulasjon av kjolevann, kombinert med an-vendelse av fyllmasse av ildfast materiale. Derved kan hensyn tas til de motstridende krav om å anordne store volum for mate- og forbrenningskamrene, og samtidig å redusere over-flaten av brennåpningene, og i dette tilfelle særlig antallet slisser. De foreslåtte konstruktive trekk har muliggjort oppnåelse av et forhold på mere enn 10 mellom maksimal og minimal avgitt gassmengde. In fig. 6 and 6a, the separation between the feed and combustion chambers consists of a cylindrical cage 37, the bars of which consist of parallel rudders 38 which pass through the upper and lower ends of the burner's outer shell 19F, to which they are sealed with openings to the outside. These rudders are arranged so closely that the distances between them form the same number of combustion slots 37F. This design is particularly suitable for use in installations that are exposed to large variations in the emitted quantities, as the flame area varies with the emitted gas quantity. In the design shown, the cage consists of rudders with a circular cross-section, but different shapes of the cross-section can be chosen according to the particular combustion problems that must be solved. Rudders with an oval cross-section or consisting of a ring section limited by two joining curves, preferably in the form of a circular arc, can be advantageously used when a reduction in the number of combustion slots must be expected. Other Ibsningers include several rudders for circulation of dressing water, combined with the use of filler material of refractory material. Thereby, account can be taken of the conflicting requirements to arrange large volumes for the feed and combustion chambers, and at the same time to reduce the surface of the combustion openings, and in this case in particular the number of slits. The proposed constructive features have made it possible to achieve a ratio of more than 10 between the maximum and minimum amount of gas released.
Generelt sett opptar brennerens mate- og forbrenningskamre Generally speaking, the burner's feed and combustion chambers occupy
det rom som omgir matekammeret. Brennerens ytre skall blir da det samme som mate- og forbrenningskammerets skall, og vanligvis er dette ytre skall forsynt med kjoleribber (ikke vist). the space surrounding the feeding chamber. The outer shell of the burner then becomes the same as the shell of the feed and combustion chamber, and usually this outer shell is provided with skirt ribs (not shown).
Alt efter sammensetningen av den gass som skal forbrennes og egenskapene av det omgivende vann,, kan f or brenning skammer et efter valg forsynes med ikke viste radiatorelementer. Anordning av slike elementer er særlig gunstig for gass med hoyt metaninnhold og med lite innhold av tunge produkter. Depending on the composition of the gas to be burned and the properties of the surrounding water, the combustion chamber can optionally be supplied with radiator elements not shown. Arrangement of such elements is particularly beneficial for gas with a high methane content and with a low content of heavy products.
Forbrenningskamrene på de beskrevne typer av brennere kan - efter valg forsynes med ror (ikke vist) for kjoling ved varmeveksling med omgivende vann. The combustion chambers of the described types of burners can - if desired - be supplied with rudders (not shown) for cooling during heat exchange with the surrounding water.
Nedsenkning av.brenneranordningen for gass slik den her er beskrevet i forskjellige utformninger, gir anordningen en tilsynelatende redusert vekt, som kan fastsettes alt efter den anbringelsesteknikk man tenker å bruke. Immersion of the burner device for gas as described here in various designs gives the device an apparently reduced weight, which can be determined according to the installation technique one intends to use.
De forskjellige utformninger av enhetsuttak for 100.000 m 3pr. dag av brennbar gass med varmeevne fra 6 til 15 "thermies"/ni<o >forer til konstruksjon av brennere med 3 til 4 meter diameter og 3 til 6 meter hoyde, idet dybden under vannflaten kan være inntil ca. 5o meter, alt. efter de lokale forhold. The different designs of unit outlets for 100,000 m 3pr. day of combustible gas with a heat capacity of 6 to 15 "thermies"/ni<o> for the construction of burners with a diameter of 3 to 4 meters and a height of 3 to 6 meters, as the depth below the water surface can be up to approx. 5o meters, all. according to local conditions.
Virkemåten av anlegget ifolge oppfinnelsen muliggjor omdannelse av betydelige mengder av gassformige hydrokarbonforbindelser som i denne tilstand er kilde til forurensning og eksplosjonsfare, til noytral gass som sendes ut i atmosfæren ved en tem-peratur som kan være under 100°C. The operation of the plant according to the invention enables the conversion of significant quantities of gaseous hydrocarbon compounds, which in this state are a source of pollution and explosion hazard, into neutral gas which is emitted into the atmosphere at a temperature which can be below 100°C.
Under drift forbruker ikke anlegget noen tilfort energi, idet de mengder luft som kreves for forbrenningen suges inn ved atmosfærisk induksjon. During operation, the plant does not consume any additional energy, as the quantities of air required for combustion are drawn in by atmospheric induction.
En hjelpevifte på noen titall kilowatt er forutsatt, for det forste for å tillate start av forbrenningen med lavt forbruk av hoytrykksgass, idet den atmosfæriske induksjon da har en dårlig virkningsgrad, og for det annet for å befri anlegget for enhver brennbar blanding efter at forbrenningen er stoppet og således unngå all eksplosjonsfare. Denne utfeining kan foretas enten med luft eller med en noytral gass så som C02- An auxiliary fan of a few tens of kilowatts is provided, firstly to allow the start of the combustion with low consumption of high-pressure gas, as the atmospheric induction then has a poor degree of efficiency, and secondly to rid the plant of any combustible mixture after the combustion is stopped and thus avoid any risk of explosion. This sweeping can be done either with air or with a neutral gas such as C02-
For en gitt dimensjon av brenneren kan dens kapasitet okes For a given dimension of the burner, its capacity can be increased
ved å erstatte den vanlige sylindriske oppbygning av trykkgass-injektor ved inntaket til blandekammeret med en konvergent/ divergent oppbygning. by replacing the usual cylindrical structure of the pressurized gas injector at the intake of the mixing chamber with a convergent/divergent structure.
For de forskjellige anlegg som kan realiseres med de beskrevne brennertyper eller disses varianter, er det mulig å foye til en gjenvinningsanordning for termisk energi i uttaksledningen for de brente gasser. Eksempelvis kan denne energi brukes til oppvarming eller levering av industriel damp eller ferskvann eller transformeres til elektrisk energi for plattformens eller andre anleggs behov. For the various facilities that can be realized with the described burner types or their variants, it is possible to add a recovery device for thermal energy in the outlet line for the burnt gases. For example, this energy can be used for heating or supplying industrial steam or fresh water or transformed into electrical energy for the needs of the platform or other facilities.
Utenfor produksjonsfeltene for hydrokarbonforbindelser kan ifolge de foreslåtte utfbrelser og spesielt ifolge den i fig. 8 viste, brukes overalt hvor der sokes oppnådd hoy termisk effekt, for eksempel for de vanndampgeneratorer som spesielt tjener til produksjon av elektrisk energi, til oppvarming og/eller industriell benyttelse. Outside the production fields for hydrocarbon compounds, according to the proposed developments and especially according to the one in fig. 8 shown, is used wherever a high thermal effect is sought, for example for the steam generators which are particularly used for the production of electrical energy, for heating and/or industrial use.
