Definitions
- the invention relates to a process for the preparation of synthetic crude oil, at a low energy cost, from a heavy crude oil or bituminous crude oil deposit.
- Extra-heavy or bituminous crudes also referred to herein as heavy crudes or bitumens, represent considerable resources that are and will be increasingly exploited.
- these crudes have physical properties including a very high viscosity and density, which make their extraction, production, transportation and treatment difficult.
- Extraction methods specific to this type of crude have therefore developed.
- One adapted to shallow or surface deposits known as the mining method, consists of mixing sand with the crude to extract and extract the mixture of sand and crude mechanically. This mixture is then washed, separated and the lighter cuts are then valorized. For deeper deposits, this method is unsuitable and it is necessary to assist production on site to make them mobile, that is to say, reduce their viscosity to make their extraction possible.
- the crude thus extracted is heavily loaded with asphaltenes and heteroatoms (S, N, O, V, Ni, etc.).
- asphaltenes and heteroatoms S, N, O, V, Ni, etc.
- they must be treated to give synthetic crudes of satisfactory quality, that is, - have a viscosity and density for pipeline transport, and low sulfur and other heteroatoms.
- the recovery stages are also very consuming natural gas, which is particularly necessary for the production of hydrogen by steam reforming of natural gas or methane (steam methane reforming according to the English terminology).
- US Pat. No. 6,357,526 proposes deasphalting to recover a deasphalted crude that constitutes the synthesis crude and the asphalt is burned to generate water vapor that is used in the SAGD extraction process.
- the synthetic crude obtained is not of good quality because it still contains many contaminants such as sulfur, nitrogen and metals. There is therefore a real need for a process for the preparation of synthetic crude from a deposit of extra-heavy or bituminous crude that makes it possible to obtain a synthetic crude of quality and whose dependence vis-à-vis the price of natural gas is reduced or canceled.
- patent FR 2 887 557 there is provided a sequence of processes integrating the extraction and treatment steps, the combustion and / or gasification of the conversion residue for generating energy in the form of steam or electricity. and / or hydrogen, the water vapor being then used for the extraction and the hydrogen for the treatment by carrying out the steps described below.
- This process avoids the use of natural gas, but requires the combustion and gasification of the residue.
- the combustion of petroleum residue by conventionally known methods is carried out by direct contact with the air. This results in significant CO 2 emissions since the fumes generally contain about 10 to 15% (by volume) of CO 2 diluted in the nitrogen of the air. It is also possible to use new oxycombustion techniques to burn the residue.
- Oxyfuel combustion makes it possible to produce fumes rich in CO 2 (at a content greater than 90% by volume) by contacting the residue only with oxygen separated beforehand from the air in an ASU (unit of air separation) or Air Separation Unit in English. Capture of CO 2 is then facilitated. The compression of the fumes then makes it possible to directly envisage a reinjection of the fumes into a storage site.
- the ASU requires a very large investment (more than 100 million euros for a unit of 350 t / h of O 2 ) and a significant energy consumption.
- the combustion cycle efficiency decreases from typically 47 to 50% for a conventional air-fired combustion plant to 39 to 42% for a unit operating in oxy-fuel combustion because of the energy consumption induced by the air separation unit.
- the gasification of the residue also requires the use of an air separation unit (ASU) to introduce the purified oxygen.
- ASU air separation unit
- the oxygen comes directly from the metal oxide which circulates continuously between a combustion zone of the hydrocarbon and a reduction zone with contact with air in which the metal reduces at the end of the combustion is reoxidized.
- the fumes contain mainly CO 2 since it is not necessary to use air.
- the gaseous effluents consist of depleted air free of oxygen captured by the metal oxides. The circulation between the two zones is carried out thanks to conventional techniques of implementation in a fluidized bed.
- the invention relates to a synthetic crude preparation process from a heavy crude oil deposits, comprising a combustion step and / or gasification of the conversion of residue in the presence of metal oxide years at least one loop cycle chemical that produces CO 2 -containing fumes (that is, at levels greater than 90%), which facilitates the capture of emitted CO2.

- the chemical loop cycle produces fumes having a CO 2 content greater than 95%.
- the rate of capture of CO2 in the chemical loop (corresponding to the percentage of CO 2 emitted by the chemical loop combustion of step (f) which exits in the form of fumes having a CO 2 content greater than 90 %) is at least 90%.
- Conversion d) can be performed by coking, visbreaking, or catalytic hydroconversion.
- the conversion rate of the conversion process d) may be adjusted so that combustion and gasification by a chemical loop f) make it possible to generate at least 50% of the quantity of water vapor required for extraction a) or at least 50% of the amount of hydrogen required for conversion d) and possibly for hydrotreatment e).
- the conversion rate of the conversion process d) can be adjusted so that the combustion and the gasification in a chemical loop f) make it possible to generate all the water vapor necessary for the extraction a) or the totality of the hydrogen necessary for conversion d) and possibly for hydrotreatment e).
- the conversion rate of the conversion process d) can also be adjusted so that the combustion and gasification in a chemical loop f) make it possible to generate all the water vapor necessary for the extraction a) and at least 50% of the the quantity of hydrogen required for conversion d) and possibly for hydrotreatment e).
- the conversion rate of the conversion process d) can be adjusted so that the combustion and the gasification in a chemical loop f) make it possible to generate all the water vapor necessary for the extraction a) and the totality of the quantity of d hydrogen necessary for conversion d) and possibly for hydrotreatment e).
- the conversion rate of the conversion process d) can also be adjusted so that the combustion and gasification in a chemical loop f) make it possible to generate all the water vapor required for the extraction a), the totality hydrogen required for conversion d) and possibly for hydrotreating e) and all the electricity required for extraction a) and conversion d) and possibly hydrotreatment e).
- a gasification of the residue is carried out in step f) and the conversion rate of the conversion process d) is adjusted so that the chemical loop gasification f) makes it possible to generate at least 50% of the hydrogen necessary for the conversion d) and optionally hydroprocessing e) and optionally at least a part of the electricity needed for the extraction a) and the conversion d) and optionally hydroprocessing e).
- the conversion rate of the conversion process d) can then be adjusted so that the chemical loop gasification f) makes it possible to generate all the hydrogen necessary for the conversion d) and possibly for the hydrotreatment e).
- Conversion d) may comprise a thermal conversion or a catalytic conversion.
- the thermal conversion is coking or visbreaking or hydroviscoreduction.
- the catalytic conversion is a catalytic hydroconversion.
- the extraction a) can be made according to a production process assisted by continuous steam injection or SAGD (steam assisted gravity drainage) or a production process assisted by cyclic steam injection or CSS (cyclic steam stimulation).
- SAGD steam assisted gravity drainage
- CSS cyclic steam stimulation
- the heavy oil has a viscosity greater than 100 cps and a density of less than 20 ° API, more preferably a viscosity greater than 1000 cps and a density of less than 15 0 API, and more preferably a viscosity of greater at 10,000 CPo and a density less than 12 0 API.
- the synthesis crude obtained has a density of at most 0.94 under standard conditions and at least 19 0 API, the viscosity being less than 350 is at 4 ° C.
- the invention proposes the integration of one or more chemical loops in a scheme for the production and recovery of heavy oils to maximize the energy efficiency of the assembly while producing fumes containing at least 90% CO 2 volume. for capture and subsequent storage of CO 2 .
- the capture rate of CO 2 in the chemical loop which corresponds to the percentage of CO 2 emitted by the outgoing chemical loop combustion in the form of concentrated fumes CO 2 (that is to say having a content of CO 2 greater than 90%, even more preferably greater than 95%) is greater than 90%.
- Chemical Loop Combustion involves contacting a hydrocarbon feedstock with a metal oxide at high temperature for combustion and / or gasification.
- the metal oxide then gives up some of the oxygen it contains, which participates in the combustion of hydrocarbons.
- the fumes mainly contain carbon oxides, water and possibly hydrogen. Indeed, it is not necessary to put the air in contact with the hydrocarbon and the smoke is therefore mainly composed of combustion gases and possibly a dilution gas used for the transport and fluidization of the particles (by example of water vapor). It is thus possible to produce fumes that are mostly free of nitrogen and contain high CO 2 contents (greater than 90% by volume), making it possible to envisage capture and then storage of CO 2 .
- the metal oxide which participated in the combustion is then transported to another reaction chamber where it is brought into contact with air to be reoxidized. If the particles returning from the combustion zone are fuel-free, the gases coming from this reaction zone are predominantly free of CO 2 -which is then only present in trace amounts, for example at concentrations below 1 to 2% by volume - and consists essentially of oxygen-depleted air, following the oxidation of the metal particles.
- the metal oxides that can be used to carry out the chemical loop combustion are generally oxides of Fe, Ti, Ni, Cu, Mg, Mn, Co, V, used alone or as a mixture. These metals can be in the form of natural ores (ilmenite) or deposited on a synthetic support or on a spent catalyst.
- these solids are packaged in the form of powder, Sauter diameter preferably between 30 and 500 microns, preferably between 50 and 300 microns, and grain density of between 1400 and 8000 kg / m3, preferably between 1400 and 5000 kg / m3.
- the charges that can be used for the chemical loop combustion are in general hydrocarbons (natural gas, liquid petroleum charges, preferably petroleum residues characterized by the fact that less than 10% of these residues boil under atmospheric conditions above 350 °, or conversion residues, generally from hydroconversion processes or asphalts, residues of the deasphalting process, or coke from coking processes.
- hydrocarbons natural gas, liquid petroleum charges, preferably petroleum residues characterized by the fact that less than 10% of these residues boil under atmospheric conditions above 350 °
- conversion residues generally from hydroconversion processes or asphalts, residues of the deasphalting process, or coke from coking processes.
- the contact between the hydrocarbon feedstock and the metal oxide requires a residence time of between 10 seconds and 10 minutes depending on the temperature which can vary from 800 to 1200 0 C, preferably between 1 minute and 5 minutes.
- the contact time between the air and the metal oxide to ensure optimum oxidation is between 10 seconds and 10 minutes depending on the temperature which can vary from 800 to 1200 0 C, preferably between 1 minute and 5 minutes.
- the mass ratio between the hydrocarbon feedstock to be burned and the circulating metal oxide is between 5 and 500, preferably between 20 and 200, and depends on the oxide used in the chemical loop.
- the implementation of a chemical loop combustion process requires significant amounts of metal oxides in contact with the fuel. These metal oxides are generally either contained in ore particles, or in particles resulting from industrial treatments (residues of the iron and steel industry or mining, catalysts of the used chemical industry or refining). It is also possible to use synthetic materials such as, for example, alumina or silica-alumina supports on which metals which can be oxidized (nickel oxide, for example) have been deposited. From one metal oxide to another, the quantity of oxygen theoretically available varies considerably and can reach high values close to 30%.
- the maximum oxygen capacity actually available generally does not exceed more than 20% of the oxygen present.
- the ability of these materials to yield oxygen thus does not exceed globally not more than a few percent by weight of the particles and varies considerably from one oxide to another, generally from 0.1 to 10%, and often between 0 and 10%. , 3 to 1% by weight.
- the use of a fluidized bed is therefore particularly advantageous for conducting combustion.
- the finely divided oxide particles circulate more easily in the combustion and oxidation reaction chambers, and between these enclosures, if the particles are given the properties of a fluid (fluidization).
- Chemical loop combustion is used to produce energy, in the form of steam or electricity, for example.
- the heat of combustion of the charge is similar to that encountered in conventional combustion. This corresponds to the sum of the heats of combustion and oxidation in the chemical loop.
- the distribution between heats of combustion and oxidation strongly depends on the metal oxides used to drive the combustion by chemical loop. In some cases, exothermicity is distributed between oxidation and metal reduction. In other cases, the oxidation is highly exothermic and the reduction is endothermic. In all cases, the sum of the oxidation and reduction heats is equal to the heat of combustion of the fuel.
- the heat is extracted by exchangers located inside, on the wall or in appendix of the combustion and / or oxidation chambers, on the flue gas lines, or on the metal oxide transfer lines.
- energy in the form of water vapor or electricity is generated in quantities adapted to respond in whole or in part to needs of the extraction phase and / or also the conversion phase and optionally hydrotreatment, and hydrogen is also generated by chemical loop in quantities adapted to respond in whole or in part to the conversion phase and optionally hydrotreating.
- a chemical loop unit is dedicated to the combustion of the residue, the other is dedicated to the production of synthesis gas (CO + H2), which can then serve as a base for the formation of hydrogen, these two units possibly being integrated with each other.
- the process according to the invention thus makes it possible to avoid the use of natural gas conventionally used for the generation of steam and hydrogen, to use the conversion residue to produce the energy required for the production of crude with energy efficiency similar to that which would be achieved in a conventional air-burning process, but producing combustion fumes containing at least 90% CO 2 and using the conversion residue to produce also synthesis gas and hydrogen without using an air separation unit.
- the process thus makes it possible, from a heavy crude, to produce a crude that can be used in refineries to produce the fuels, while making it possible to capture the CO 2 resulting from the energy requirements of the production.
- Using the conversion residue to produce water vapor and / or hydrogen and / or electricity can also result in a substantial saving in the investment required for conversion facilities. Indeed, the capacities of the conversion plants can be limited firstly because the separation residue can also be used to generate water vapor and / or electricity and / or hydrogen, and secondly because the required level of conversion can be limited, the operating conditions of the conversion can then be less severe (in particular, reduced residence time).

- the conversion rate to T540 + * is defined as the ratio of:
- the extraction a) is preferably carried out according to a production technology assisted by continuous steam injection or SAGD (steam assisted gravity drainage) or a production technology assisted by cyclic steam injection or CSS ( cyclic steam stimulation), that is to say by technologies requiring very large amounts of water vapor and therefore energy.

- CSS cyclic steam stimulation
- separation c) involves at least one physical separation process such as distillation or solvent extraction.
- the distillation may be distillation at atmospheric pressure or else distillation at atmospheric pressure followed by distillation under vacuum. Atmospheric distillation can also be followed by deasphalting, ie solvent extraction separation.
- the heavy fraction resulting from these separation operations which contains asphaltenes is then upgraded to lighter products.
- the conversion d) can be thermal (coking, visbreaking) or catalytic (catalytic hydroconversion).
- coking is carried out on the heavy fraction of a vacuum residue.

- the coke production corresponds to 20% to 35% of the feedstock entering the coking unit according to the nature of the feed and the operating conditions, which corresponds to a crude conversion rate of the coking of 65 to 80%. If this gross conversion rate is insufficient to provide all the water vapor and hydrogen and / or electricity requirements, a cut, preferably a heavy cut from the coker can also be used to supplement the amount of fuel.
- This thermal conversion unit can also be a visbreaking unit.
- the visbreaking can also be carried out in the presence of hydrogen to promote the stability of the products. This is called hydroviscoreduction. T540 + conversions of 25% to 45% can be obtained.

- the catalyst remains in the reactor and is added or withdrawn independently of the feed.
- the catalyst is generally continuously introduced with the fresh feedstock into the reactor and consists of soluble elements containing one or more metals which can be sulfided under the process conditions.

It can also be a catalytic conversion unit (for example catalytic hydroconversion of residues in fixed bed, moving bed, bubbling bed or driven slurry reactor).
- Example 1 Standard Combustion and Production of Hydrogen by Steam Reactor Athabasca heavy or bituminous crude is withdrawn by a SAGD type process. After separation of water and crude, the crude is subjected to atmospheric distillation. The atmospheric residue obtained (RAT) has the characteristics given in Table 1 below. This atmospheric residue undergoes hydroconversion. The conversion rate of the hydroconversion is adjusted to provide the necessary amount of residue (500 ° C +) to feed a conventional boiler fueled by residue and air to produce the steam needed for the production of the crude heavy or bituminous. To produce 100 000 BPSD of heavy crude or bitumen by SAGD, knowing that the ratio steam / crude produced is 2 barrels of water vapor per barrel of crude oil, it will be necessary to inject into the ground close to 1350 t / h steam.
- the conversion level of the hydroconversion must lead to having 123 000 kg / h of residue to supply the boiler.
- the hydroconversion conversion rate must therefore be 78%.
- the contribution of hydrogen for the recovery is an external supply of hydrogen obtained by Steam Methane Reforming of natural gas. 19t / h of hydrogen are necessary, which corresponds to a consumption of 66t / h of natural gas.
- the amount of CO 2 emitted by the boiler is 387000 kg / h, diluted in fumes containing essentially nitrogen and water vapor, the volume concentration of CO 2 being close to 14% vol.
- Nitrogen oxides and sulfur oxides were captured upstream of the flue gas discharge by conventional methods well known to those skilled in the art.
- Athabasca heavy or bituminous crude oil is withdrawn by a SAGD type process. After separation of water and crude, the crude is subjected to atmospheric distillation.
- the atmospheric residue obtained (RAT) has the characteristics given in Table 2 below. This atmospheric residue undergoes hydroconversion.
- the conversion rate of the hydroconversion is adjusted to provide the necessary amount of residue (500 ° C +) to feed an oxycombustion boiler fed with residue and oxygen to produce the steam needed for production. heavy or bituminous crude.
- oxycombustion is lower than that of a conventional combustion boiler.
- the conversion rate of the hydroconversion can then be lowered to 73%.
- the conditions for hydroconversion are as follows:
- the hydrogen input for recovery is an external supply of hydrogen obtained by Steam Methane reforming natural gas. 18.3 t / h of hydrogen are needed, which corresponds to a consumption of 64t / h of natural gas.
- the quantity of CO 2 emitted by the boiler is 463000 kg / h concentrated thanks to the implementation of the oxycombustion process, the volume concentration of CO 2 being close to 95% vol.
- Nitrogen oxides and sulfur oxides were captured upstream of the flue gas discharge by conventional methods well known to those skilled in the art
- Athabasca heavy or bituminous crude oil is withdrawn by a SAGD type process. After separation of water and crude, the crude is subjected to atmospheric distillation.
- the atmospheric residue obtained (RAT) has the characteristics given in Table 3 below. This atmospheric residue undergoes hydroconversion.
- the conversion rate of the hydroconversion is adjusted in order to have the necessary amount of residue (500 0 C + ) to feed a boiler operating with the chemical loop and fed with residue.
- the material used to operate the chemical loop is ilmenite.
- the temperature of the combustion zone is 995 ° C.
- the conversion rate of the hydroconversion can then be lowered to 77%.
- the conditions of the hydroconversion are therefore as follows: average temperature: 417 ° C partial pressure in H 2 : 130 bar conversion to T540: 0.77
- the hydrogen input for recovery is an external supply of hydrogen obtained by Steam Methane reforming natural gas. 18.7 t / h of hydrogen is needed which corresponds to a consumption of 65 t / h of natural gas.
- the characteristics of the crude after hydroconversion are given in Table 3 below.
- the material balance of the hydroconversion is as follows:% by weight
- the amount of CO 2 emitted by the boiler is 394000 kg / h concentrated thanks to the implementation of the oxycombustion process, the volume concentration of CO 2 being close to 97% vol.
- Nitrogen oxides and sulfur oxides were captured upstream of the flue gas discharge by conventional methods well known to those skilled in the art
- the chemical loop produces combustion fumes at least as concentrated in CO 2 as oxy-fuel combustion.
- the chemical loop makes it possible to produce about 5000 BPD more than the oxycombustion, that is to say to be at the same level as the conventional combustion processes, which do not make it possible however to concentrate the fumes in CO 2 .
- This improved production, associated with a high concentration of CO 2 fumes, is related to the greater efficiency of the energy cycle implemented in the chemical loop combustion process.
