Vapor of the water is sent to the underground hydrocarbon tank, and carbon dioxide (17) in waste gases is sent for assisted recuperation hydrocarbon. An independent claim is also included for an apparatus for producing oxygen for an oxy-combustion unit and fluid for assisted recuperation of hydrocarbon such as petrol, comprising a compressor.

Description

La présente invention a pour objet un procédé de production d'oxygène pour une unité d'oxycombustion et de fluide pour la récupération assistée d'hydrocarbures. L'oxycombustion est la combustion d'un combustible fossile avec de l'oxygène, ou de l'air enrichi en oxygène comme comburant. Les procédés de drainage gravitaire par injection de vapeur permettent de récupérer du pétrole d'un réservoir souterrain en y injectant de la vapeur d'eau. The present invention relates to a process for producing oxygen for an oxycombustion and fluid unit for the enhanced recovery of hydrocarbons. Oxycombustion is the combustion of a fossil fuel with oxygen, or oxygen enriched air as an oxidizer. Gravity-fed gravity drainage processes are used to recover oil from an underground reservoir by injecting water vapor into it.

L'injection d'eau sous forme liquide est également un moyen d'augmenter la productivité d'un champ pétrolier. Il est également connu d'utiliser du dioxyde de carbone dans un procédé de récupération assistée de pétrole. Dans la présente invention, on cherche à limiter l'impact environnemental des procédés de récupération assistée de pétrole en réduisant la quantité d'eau provenant des sources naturelles, telles que les rivières et les nappes phréatiques, en la remplaçant par de l'eau provenant de la condensation de l'humidité présente dans l'air. Selon un autre objet de l'invention, il est prévu un procédé de production d'oxygène pour une unité d'oxycombustion et de fluide pour la récupération assistée de pétrole dans lequel : i) on comprime un débit d'air dans un compresseur et on récupère de l'eau de condensation d'au moins un étage du compresseur, ii) on envoie l'air comprimé à un appareil de séparation d'air où l'on produit de l'oxygène, iii) on envoie l'oxygène à l'unité d'oxycombustion et iv) on envoie l'eau, éventuellement après vaporisation, à un procédé de récupération assistée d'hydrocarbures, tel que le pétrole. Selon d'autres objets facultatifs : - on envoie un débit d'eau sous forme liquide à un réservoir souterrain d'hydrocarbures, tel que le pétrole. - on vaporise l'eau et on envoie la vapeur d'eau à un réservoir souterrain d'hydrocarbures, tel que le pétrole. - on récupère du dioxyde de carbone dans les gaz résiduaires de l'oxycombustion et on envoie le dioxyde de carbone au procédé de récupération assistée d'hydrocarbures, tel que le pétrole. Selon un autre objet de l'invention, il est prévu un appareil de production d'oxygène pour une unité d'oxycombustion et de fluide pour la récupération assistée d'hydrocarbures, tel que le pétrole comprenant: i) Un compresseur pour comprimer un débit d'air dans un compresseur et des moyens pour récupérer de l'eau de condensation d'au moins un étage du compresseur, ii) Un appareil de séparation d'air, des moyens pour envoyer de l'air du compresseur à l'appareil de séparation d'air et des moyens pour soutirer de l'oxygène de l'appareil de séparation d'air, iii) Une conduite pour envoyer l'oxygène de l'appareil de séparation d'air à l'unité d'oxycombustion et iv) Une conduite pour envoyer l'eau de condensation récupérée, éventuellement après vaporisation, à un réservoir souterrain d'hydrocarbures. Eventuellement l'appareil comprend : - une chaudière, une conduite pour envoyer l'eau récupérée à la chaudière et une conduite pour envoyer la vapeur d'eau de la chaudière au réservoir souterrain d'hydrocarbures. - des moyens pour récupérer du dioxyde de carbone de l'unité d'oxycombustion et pour l'envoyer au réservoir souterrain d'hydrocarbures. L'invention sera décrite en plus de détail en se référant à la figure qui illustre un procédé selon l'invention. Un débit d'air atmosphérique humide est comprimé dans un compresseur 1. L'air ainsi comprimé 3 est envoyé à un appareil de séparation d'air par distillation cryogénique 5 qui produit un débit d'oxygène gazeux 7. L'oxygène gazeux 7 est envoyé à une unité d'oxycombustion 9. Les gaz résiduaires de l'oxycombustion sont épurés par exemple par distillation cryogénique pour former un gaz riche en dioxyde de carbone 17. L'unité d'épuration n'est pas illustrée et peut être comme partie intégrante de l'unité d'oxycombustion 9. Ce gaz riche en dioxyde de carbone 17 est envoyé à un réservoir souterrain de pétrole 19. The injection of water in liquid form is also a way to increase the productivity of a petroleum field. It is also known to use carbon dioxide in an enhanced oil recovery process. In the present invention, it is sought to limit the environmental impact of enhanced oil recovery processes by reducing the amount of water from natural sources, such as rivers and groundwater, by replacing it with water from condensation of moisture in the air. According to another object of the invention, there is provided a method for producing oxygen for an oxycombustion and fluid unit for enhanced oil recovery in which: i) compressing a flow of air in a compressor and at least one stage of the compressor is recovered, ii) compressed air is sent to an air separation unit where oxygen is produced, and at the oxycombustion unit and iv) the water, possibly after vaporization, is sent to a process for the enhanced recovery of hydrocarbons, such as oil. According to other optional objects: - a flow of water in liquid form is sent to an underground reservoir of hydrocarbons, such as oil. - The water is vaporized and the steam is sent to an underground reservoir of hydrocarbons, such as oil. - Carbon dioxide is recovered from the oxyfuel exhaust gases and carbon dioxide is sent to the enhanced hydrocarbon recovery process, such as oil. According to another object of the invention, there is provided an apparatus for producing oxygen for an oxycombustion and fluid unit for the enhanced recovery of hydrocarbons, such as oil comprising: i) A compressor for compressing a flow rate of air in a compressor and means for recovering condensation water from at least one stage of the compressor, ii) an air separation apparatus, means for sending air from the compressor to the apparatus for separating air and means for withdrawing oxygen from the air separation apparatus; iii) a conduit for supplying oxygen from the air separation apparatus to the oxy-fuel combustion unit and iv) A pipe to send the condensed water recovered, possibly after vaporization, to an underground hydrocarbon reservoir. Possibly the apparatus comprises: - a boiler, a pipe for sending the recovered water to the boiler and a pipe for sending water vapor from the boiler to the underground hydrocarbon tank. means for recovering carbon dioxide from the oxycombustion unit and for sending it to the underground hydrocarbon reservoir. The invention will be described in more detail with reference to the figure which illustrates a method according to the invention. A flow of moist atmospheric air is compressed in a compressor 1. The compressed air 3 is sent to an air separation apparatus by cryogenic distillation which produces a flow rate of oxygen gas 7. The oxygen gas 7 is sent to an oxy-fuel combustion unit 9. The oxycombustion waste gases are purified for example by cryogenic distillation to form a gas rich in carbon dioxide 17. The purification unit is not illustrated and can be as a part This gas rich in carbon dioxide 17 is sent to an underground tank of oil 19.

L'eau de condensation 11 produit par la compression d'air humide dans le compresseur 1 est envoyée à une chaudière 13 pour produire de la vapeur d'eau 13. La chaudière est également alimentée par d'autres sources d'eau provenant par exemple d'une nappe phréatique ou d'une rivière. La vapeur d'eau produire par la chaudière peut servir à la récupération assistée de pétrole dans un procédé de type SAGD (drainage gravitaire de pétrole par injection de vapeur d'eau) pour extraire le pétrole lourd. De plus, l'eau 11 peut aussi être pressurisée et injectée dans le réservoir pétrolifère afin d'augmenter la productivité de celui-ci. The condensation water 11 produced by the compression of moist air in the compressor 1 is sent to a boiler 13 to produce water vapor 13. The boiler is also fed by other sources of water from, for example a water table or a river. The water vapor produced by the boiler can be used for enhanced oil recovery in a SAGD (gravity-fed gravity drainage) process for extracting heavy oil. In addition, the water 11 can also be pressurized and injected into the oil reservoir to increase the productivity thereof.

Le procédé peut évidemment s'appliquer à l'extraction d'hydrocarbures autres que le pétrole, par exemple le gaz naturel. The process can obviously be applied to the extraction of hydrocarbons other than petroleum, for example natural gas.
