Definitions

  • the invention relates to the chemical process of combustion of hydrocarbon fuel, in particular, to the process of combustion of hydrocarbon gases, hydrocarbon liquids, oil residues, to produce thermal energy for its subsequent beneficial use, as well as the capture/recovery of carbon dioxide for subsequent transportation to storage and reduction sites greenhouse gas emissions into the atmosphere.
  • the closest analogue is the method of fuel combustion with subsequent capture of carbon dioxide US2009075219 (A1), published on March 19, 2009.
  • the method includes supplying an oxygen flow to the combustion chamber with subsequent condensation of water vapor, releasing part of the flue gases into the atmosphere and part of the flue gases to the capture process carbon.
  • the disadvantage of this method is the inability to regulate the concentrations of components in the flue gas flow for oxygen in the concentration range from 1% vol. up to 50% vol., for carbon dioxide from 1% vol. up to 50% vol., nitrogen concentration no more than 30% vol., as well as the need for condensation of water vapor, which is ensured by reducing the temperature of the flue gases to 15 °C, which in turn requires significant operating costs for cooling.
  • the patent also does not include the recirculation of the flue gas flow back into the combustion process zone of hydrocarbon gas, hydrocarbon liquid, oil residues and the recirculation of the carbon dioxide and nitrogen flow after the carbon capture process in order to regulate the concentration of components in the combustion zone.
  • the objective of the claimed invention is to develop a method for burning hydrocarbon fuels in order to integrate with the carbon dioxide capture process, allowing to reduce the operating costs of the capture process by up to 40% and increase the concentration of carbon dioxide in the flue gas stream by up to 50%.
  • the technical result of the proposed invention is a reduction in operating costs for the carbon dioxide capture process by 40% and a proportional reduction in greenhouse gas emissions into the atmosphere due to capture and transportation to storage sites.
  • the specified technical result is achieved due to the fact that the combustion method is carried out for hydrocarbon gas, hydrocarbon liquid, oil residues while ensuring combustion in flows with a given concentration of oxygen, nitrogen and carbon dioxide in the required proportions, for oxygen in the concentration range from 1% vol. up to 50% vol., for carbon dioxide from 1% vol. up to 50% vol., minimum nitrogen concentration up to 30% vol.
  • Atmospheric air is supplied to the station/installation for separation into components, containing nitrogen and oxygen in a proportion of 79% vol. and 21% vol.
  • the oxygen flow is directed as an oxidizer to the fire heater to ensure the combustion process of the hydrocarbon gas, hydrocarbon liquid, oil residues at a temperature of 800-1400 °C.
  • the resulting flue gases from the combustion of hydrocarbon fuels are sent to a smoke exhauster/compressor to feed the carbon capture process. A portion of the flue gas flow from the smoke exhauster/compressor is recycled back to the oxygen flow to regulate the concentration of carbon dioxide, nitrogen and oxygen in the hydrocarbon fuel combustion zone.
  • a portion of the carbon dioxide and nitrogen stream from the carbon capture process is fed as a recycle stream back to the oxygen stream to control the concentration of carbon dioxide, nitrogen and oxygen in the hydrocarbon fuel combustion zone.
  • Atmospheric air is supplied to the station/installation for separation into components (5) - nitrogen and oxygen.
  • the oxygen flow is sent as an oxidizer to the fire heater (1) to ensure the combustion of hydrocarbon fuel.
  • the resulting flue gases from the combustion of hydrocarbon fuels are sent to the smoke exhauster/compressor (3) to feed the carbon capture process (4).
  • a portion of the flue gas stream from the exhaust fan/compressor can be recycled back to the oxygen stream to control the concentration of carbon dioxide, nitrogen and oxygen in the hydrocarbon fuel combustion zone of the heater/evaporator (1).
  • Flue gas recycle can range from 0.1 to 1000 parts per 1 part hydrocarbon fuel.
  • a portion of the carbon dioxide and nitrogen stream from the carbon capture process (4) may be supplied as a recycle stream back to the oxygen stream to control the concentration of carbon dioxide, nitrogen and oxygen in the hydrocarbon fuel combustion zone of the heater/evaporator (1).
  • the recycle of carbon dioxide and nitrogen from the capture process (4) can range from 0.1 to 1000 parts per 1 part hydrocarbon fuel.
  • oxygen flow, flue gas recycle and carbon dioxide recycle after the carbon capture process makes it possible to increase the concentration of carbon dioxide in the flue gas stream from 12% vol. up to 50% vol. , which fundamentally simplifies the organization of the carbon capture process, reduces capital and operating costs for capturing 1 ton of carbon.
  • carbon dioxide recycle allows you to reduce the concentration of nitrogen, which is a diluent and an inert gas that significantly complicates the operation of the carbon capture process (4),
  • (3) - smoke exhauster/compressor a device that provides transport of the volume of flue gases from the fire heater/evaporator to the process of capturing carbon from the flue gases, as well as recycling part of the flue gases back to the fire heater/evaporator;
  • the combustion process is carried out for hydrocarbon gas in an amount of 100 kg/h.
  • atmospheric air is supplied in proportion to the station/installation for separation into components in an amount of up to 150 kg/h, containing nitrogen and oxygen in a proportion of 21% vol. and 79% vol.
  • the oxygen flow is sent as an oxidizer to the fire heater to ensure the combustion of hydrocarbon gas at a temperature of 900-1100 °C.
  • the resulting flue gases from the combustion of hydrocarbon fuels are sent to a smoke exhauster/compressor to feed the carbon capture process.
  • a portion of the flue gas flow from the smoke exhauster/compressor is recycled back to the oxygen flow to regulate the concentration of carbon dioxide, nitrogen and oxygen in the hydrocarbon fuel combustion zone.
  • the oxygen concentration is 42% vol. , carbon dioxide 29% vol., nitrogen 29% vol.
  • a portion of the carbon dioxide and nitrogen stream from the carbon capture process is fed as a recycle stream back to the oxygen stream to control the concentration of carbon dioxide, nitrogen and oxygen in the hydrocarbon fuel combustion zone.
  • the recycle of carbon dioxide and nitrogen from the capture process is up to 100 parts per 1 part hydrocarbon fuel.

Abstract

L'invention concerne un processus chimique de combustion de combustible hydrocarbure, notamment un processus de combustion de gaz hydrocarbures, de liquides hydrocarbures et de résidus pétroliers. On procède à un allumage du combustible dans un mélange d'un flux de recyclage d'effluents gazeux formés lors du processus de combustion, d'un flux de recyclage de dioxyde de carbone et d'azote, d'un flux d'oxygène et d'un flux d'air atmosphérique; évacuer les effluents gazeux de la zone de combustion du combustible avec un recyclage partiel des gaz vers la zone de combustion; envoyer une quantité d'équilibrage d'effluents gazeux vers un processus d'extraction de dioxyde de carbone et le diriger vers un stockage, séparer le condensat d'eau et le produit de recyclage du dioxyde de carbone vers la zone de combustion. Ce procédé permet d'augmenter l'efficacité de piégeage de dioxyde de carbone depuis un flux d'effluents gazeux afin de le stocker ensuite et de réduire les actions néfastes sur l'atmosphère.
