Definitions
- the present invention relates to a method and a plant for storing CO 2 stemming from an industrial process as synthetic or substitute natural gas.
- post-combustion capture e.g. by amine scrubbing of the CO 2
- oxyfuel-processes which lead to nitrogen-free flue gases. While the disadvantage of the scrubbing is the high energy demand for the scrubbing liquid regeneration, the oxyfuel concepts suffer from the high electricity demand for the air separation unit to deliver the pure oxygen.
- this goal is achieved according to the present invention by a method for storing CO2 stemming from an industrial process as synthetic or substitute natural gas,
- a plant for storing C02 stemming from an industrial process as synthetic or substitute natural gas comprising:
- an industrial operation plant generating CO2 comprised in a flue gas; said industrial operation plant performing an industrial combustion or calcination process or a
- a CO2 separating unit for separating a CO2 containing gas mixture from the flue gas
- a methanation unit for converting the C02 containing gas mixture and the H2 by a methanation reaction to a methane rich gas which can be used as or upgraded to synthetic natural gas.
- the present invention forms an integrated process to combine the four steps (combustion and/or calcination of cement; CO 2 separation; electrolysis to produce H 2 and O 2 ;
- the industrial C02-source may be a cement plant.
- the C0 2 -separation can be conducted in a scrubber unit and the heat of the methanation reaction can be at least partly used to regenerate a scrubbing liquid used in the scrubber unit.
- the C0 2 -separation is conducted in a temperature swing adsorption reactor and the heat of the methanation reaction is at least partly used to regenerate the sorbents used in the temperature swing adsorption reactor.
- Further suitable alternative may provide for an energy- efficient C0 2 -separation wherein the C02-separation may be conducted in a membrane or a pressure swing adsorber or in a chemical looping reactor.
- the heat of the methanation reaction may be at least partly used to increase the efficiency of the water electrolysis .
- the oxygen stream from the water electrolysis and/or the heat from the methanation reaction may be at least partly used in the industrial combustion or calcination process to increase the thermal efficiency and/or to increase the CO 2 partial pressure which facilitates CO 2 separation and/or to regenerate the chemical looping material.
- a high pressure electrolysis may be applied, and the expansion of the hydrogen and/or oxygen from the electrolysis pressure down to the conditions in the combustion/calcination or the methanation unit is used to generate mechanical energy, which is used for gas compression (e.g. of the flue gas or the C02 rich gas stream) and/or for electricity production in terms of turbine expansion.
- gas compression e.g. of the flue gas or the C02 rich gas stream
- electricity production in terms of turbine expansion.
- a continuous operation may be desirable.
- hydrogen, oxygen, flue gas and/or CO2 may be stored in local storage devices to enable continuous operation of at least some unit operations.
- hydrogen and/or CO2 may be separated in a gas up grading downstream of the methanation reaction and may be fed back to the methanation reaction.
- Figure 1 schematically an overview of the synergetic effects of combining diverse industrial processes
- Figure 2 schematically an alternative overview with respect to Figure 1.
- Figure 1 shows an overview of the synergetic effects of the combination of an industrial combustion operation, water electrolysis, CO2 separation and methanation.
- the CO2 from the combustion process here a cement kiln
- the CO2 emission of the combustion process which drives the cement kiln is decreased.
- Hydrogen from a water electrolysis run by cheap or excess electricity is also fed to the methanation unit. This will allow storing cheap or excess electricity.
- the raw SNG produced in the methanation unit is upgraded and may be injected into the grid where it can be stored, transported, used as fuel (e.g. for CNG cars) or be utilised for electricity production at a different time or location (e.g. by combined cycle power plants or combined heat and power plants) .
- the heat of the methanation reaction is used for the energy demanding regeneration of scrubbing liquids in case of a liquid scrubber based C02 separation or for the thermal regeneration of sorbents in case of applying temperature swing adsorption.
- the heat of the methanation reaction can be used for heating up gases, increase the efficiency in the electrolysis or drying of fuels or other heat integration purposes.
- the oxygen from the water electrolysis is fed to the
- combustion process in this example the cement kiln and/or the preheater and/or the calciner
- exhaust gas treatment step and/or into conditioning step for the feedstock fed to the combustion process.
- the separation is accomplished by a chemical looping process (see Figure 2) .
- at least part of the oxygen from the electrolysis will be fed to the regeneration of the sorbent (e.g. by calcination) to allow for a nearly nitrogen-free CO 2 stream.
- the expansion of the hydrogen and oxygen from the electrolysis pressure down to the conditions in the combustion or the methanation unit may be used to generate mechanical energy, which could be used for either gas compression (e.g. of the flue gas or the C02) and/or for electricity production.
- hydrogen, oxygen, flue gas and/or CO 2 could be stored in local storage devices (e.g. gas containers) to enable more continuous operation of at least some unit operations .
- hydrogen and/or CO 2 could be fed in excess or be present in the outlet of the methanation unit (e.g. due to incomplete conversion) .
- 3 ⁇ 4 and or CO 2 would be separated in the gas up grading and fed back to the
- methanation unit Especially, running 3 ⁇ 4 in excess may help to overcome equilibrium limitations and may support catalyst stability in the methanation reactor.
- the heat for the regeneration of scrubbing liquids could be taken from other heat sources within the process, e.g. the streams leaving the combustion step or calcination kiln.
- any heat source within the process i.e. from the calcination, combustion and/or methanation unit, may be used to produce electricity.
- depleted flue gas could be recycled to the combustion process or cement kiln to improve heat management.
- part of or even the complete flue gas flow could be fed directly to the gas cleaning and methanation reactor.
- the methanation unit could be of any reactor type, but
- the catalyst in the methanation unit could contain any elements helpful for the desired reactions, especially Ni, Ru, Rh, Ir, Co, Mo and/or their oxides, sulphides etc.
- sulphur resistant catalysts or catalysts allowing for regeneration may be applied. In this case, sulphur resistant catalyst supports may be helpful.
- the sorbent in the chemical looping CO 2 separation may be chosen, modified or supplemented by suited materials such that besides the C0 2 ⁇ separation, further gas cleaning is accomplished, e.g. desulphurisation or separation of metals, chlorine, nitrogen compounds etc.
Abstract
L'objectif de la présente invention consiste à fournir un procédé et une unité pour l'exploitation la plus efficace d'une opération industrielle, en stockant de ce fait le CO2 généré par cette opération industrielle de telle sorte que des procédés ultérieurs tirent avantage de l'énergie stockée dans le CO2 séparé de l'opération industrielle (où le CO2 peut être soumis à une conversion en un autre produit, tel que le GNS). Cet objectif est atteint selon la présente invention par un procédé et une unité pour le stockage du CO2 provenant d'un processus industriel sous forme d'un gaz naturel de synthèse ou de substitution, comprenant : a) une unité d'exploitation industrielle produisant du CO2 compris dans un gaz de carneau ; ladite unité d'opération industrielle réalisant un processus industriel de combustion ou de calcination ou un processus métallurgique ; b) une unité de séparation du CO2 pour séparer un mélange gazeux contenant du CO2 du gaz de carneau ; c) une unité d'électrolyse pour dissocier l'eau par électrolyse pour produire du H2 et du O2 ; d) une unité de méthanation pour convertir le mélange gazeux contenant du CO2 et le H2 par une réaction de méthanation pour donner un gaz riche en méthane qui peut être utilisé en l'état, ou valorisé en gaz naturel de synthèse. En conséquence, la présente invention forme un processus intégré pour combiner les quatre étapes (combustion et/ou calcination du ciment ; séparation du CO2 ; électrolyse pour produire du H2 et du O2 ; méthanation) d'une manière synergique pour résoudre les deux problèmes décrits ci-dessus avec une efficacité significativement plus élevée que ce qui est possible dans des unités non intégrées.
