Definitions
- the present invention relates to a process for producing shale hydrogen.
- shale hydrogen is obtained from shale gas or shale oil which is extracted by drilling, this shale gas (or oil) is then directly converted into hydrogen in a production unit of hydrogen by reforming or partial oxidation in which the carbon dioxide is extracted, then liquefied and is recycled in the borehole or it will be used to extract the gas (or oil) and in which it will finally be sequestered, the hydrogen obtained is used directly in a power plant located on the site and / or injected into a hydrogen distribution network built for this purpose.
- the shale hydrogen thus produced and distributed is the cheapest clean fuel on the market and its price is of the order of magnitude of the price of natural gas, ie € 25 / MWh, and this by amortizing investments with returns on investments 25%. If a carbon tax of € 50 per tonne is implemented, it becomes the cheapest fuel on the all energy market.
- This shale hydrogen achieves a reduction of three to four GHG emissions from a country like France and by 2040 is better than the European target and better than the desired objective at COP21.
- GigaHydrogen Plant or Giga Plant a unit whose power exceeds 2250MW (2.25GW) and typically 4500 MW (4.5GW).
- Hydraulic fracturing is a fairly old technique, several authors indicate the year 1949 as the date of the first fracturing, since millions of wells were drilled. In the United States some wells have posed environmental problems as a result of non-compliance with good operating practices. Hydraulic fracturing is done by injecting water or a pressurized gas that may be carbon dioxide, nitrogen, propane, petroleum-based fluids. Carbon dioxide is not hitherto used in view of its cost, the propane of its flammability.
- Carbon dioxide is known for its exceptional solvent properties when used at supercritical pressure, pressure above 72.9 bar.
- Hydrogen can be transported by hydrogen pipeline, the largest existing is exploited in the Ruhr by Hùls, its length is 210 km long, its low capacity of 1 billion m3 / year corresponds to one fifth of the capacity of a Mega-factory of 2250MW.
- Greenhouse gases not including water vapor, account for about three-quarters of the CO2 emitted by fossil fuels when they burn.
- the reduction of greenhouse gases that would be necessary to control the rise in temperatures of 2 degrees as proposed by COP21 is very difficult to achieve because there is no real way today to avoid these discharges.
- the measures to limit global warming include wind and solar which unfortunately require wind and sun to operate and produce electricity that we do not know how to store today.
- the present invention relates to a process for producing hydrogen from shale gas (or shale oil) in which:
- the produced shale gas (or oil) is converted to hydrogen by catalytic steam reforming or by partial oxygen oxidation of the air in a Mega (225 OMW) or a Giga (4.5 GW) plant located at proximity.
- the cost price of shale hydrogen thus produced and distributed is of the order of magnitude of the price of imported natural gas with equivalent energy content and this including investments with a return time of less than four years, it can therefore substitute fossil fuels today used.
- the invention thus makes it possible to reduce greenhouse gas emissions to a lower level than those expected by COP21 (United Nations Conference on Climate Change).
- the carbon mass content can vary from 65% (lignite) to 90% (coal), sulfur from 0.5 to 2%, hydrogen from 4 to 6%, water from 3 to 12%, volatile 10 to 40%, minerals from 3 (lignite) to 16%. There will therefore always ash and slag for about 10% of the load which is already the case in case of direct combustion.
- Coal gasification is based on the following main reactions:
- the actual gasification reaction is the partial oxidation of carbon by the following water: C + H 2 0 ⁇ H 2 + CO
- This reaction is what we call the carbon conversion reaction.
- the most commercialized technologies are driven fluid gasifiers with a temperature of 1400 to 1700 ° C and a pressure of 35 to 70 bar.
- the gasifier consists of a hollow chamber lined with refractory bricks.
- the single burner installed at the top of the reactor, is fed with pulverized coal, as well as steam and oxygen, the gases and the slag (10% of the supply) leave in the lower part of the apparatus.
- Oxygen is produced in an air separation unit by cryogenics.
- the gases are filtered through cyclones and / or ceramic candles which retain the particles.
- Carbonyl sulphide (COS) is then hydrolysed. Excess water is treated and sent to sulfur recovery.
- a succession of gas-to-water reactions makes it possible to adjust the CO / H2 ratio to the desired value.
- the acid gases are then extracted either by chemical, physical or combined absorption.
- the BASF solution to use an activated MDEA is very often used because of reasonable investment costs and high performance (less than 10 ppm CO2) in the synthesis gas.
- the different streams containing sulfur generally feed a unit according to Claus process which generates sulfur.
- This scheme could produce only hydrogen by adapting the gas reactions to water in a cascade of reactors, but it will be necessary to purify the hydrogen thus produced and recycle or purge the impurities (nitrogen).
- the practical hydrogen is about 1.3 moles of hydrogen for a theoretical of 2.5, which means that part of the carbon is used to heat the charge.
- the cost of a unit corresponding to an equivalent of 5000 T / d of methanol is approximately 1.5 billion euros, which is approximately 3 to 4 times the cost of a similar unit on natural gas, to which must be added the cost of sequestration of CO 2 produced.
- the amount of coal treated per hour is of the order of 250 T / h of coal at 75% by weight, ie about 2 million T / year.
- Natural gas is composed mainly of methane, so we will often talk about methane instead of natural gas in what follows.
- the main reaction is as follows:
- the natural gas is sent into the steam reformer at pressures of 20 to 30 bar, the feed is then preheated to 500-550 ° C. (examples known by the author on very small units 505 ° C. and 520 ° C).
- the steam reformer consists of tubes filled with catalyst and heated externally by burners fed with natural gas which reduces the theoretical yield.
- the synthesis gas leaves the reformer at 885 ° C, it is cooled a first time to generate 40 bar steam, it then passes through reactors (shift reactors) in which the reaction of the gas with water is carried out to convert the CO to CO2 and at the same time reduce the water to hydrogen, it is cooled a second time to preheat the water supplying the steam generator, it is finally cooled with water to 50 ° C.
- An absorption (activated M DEA-BASF method for example) is then carried out to separate the CQ 2 and reach a residual CO 2 of less than 100 ppm.
- the separated CO 2 can be compressed by a turbine driven by the steam H produced, it will then be used to carry out the fracturing in gas form or in liquid form in the hypo or hypercritical state.
- the gaseous mixture now contains residual methane, CO 2 and residual CO, hydrogen and nitrogen.
- Numerous processes make it possible to separate the hydrogen: PSA (pressure swing adsorption on molecular sieves), anaerobic digestion, membranes, cryogenic distillation, ....
- PSA pressure swing adsorption on molecular sieves
- the other compounds are recyclable in the unit subject to purging the nitrogen q ui can be used for fracturing.
- PSA can extract 85% of the hydrogen present in the mixture.
- the mixture can then be methanized to convert the residual carbon oxides to methane.
- the remaining compounds, methane, residual hydrogen and nitrogen are then separated by membrane processes, by cryogenic distillation or other processes, the methane and hydrogen will thus be fully recovered.
- the natural gas is sent to a reactor coated with refractory at pressures of 20 to 90 bar, and at temperatures of 1200 to 1500 ° C. Part of the charge is injected into a burner mounted at the top of the reactor.
- the treatment of gases leaving the reactor is similar to that of steam reforming: gas-to-water reactors, actual treatment and recycling of recoverable products.
- the reactor is a vertical cylindrical reactor on which is mounted at the top a burner and whose bottom is filled with catalyst, (ref 1)
- This reaction can be done in a prereforming.
- the reaction mechanism follows three consecutive steps:
- the ICP of the methane is 803.3 kJ / mol
- the calculation is made for a 2250MW mega plant including the corresponding part of the distribution network.
- the cost estimate is based on the following two projects.
- GTL's Oryx Qatar (ref3) manufacturing project ($ 1billion investment) includes two synthesis gas production lines equipped with autothermal reforming, which represents 2/3 of the total amount and for which air separation represents 50% . These two lines are fed by a natural gas flow of 330 million cubic feet / day corresponding to the supply of a unit of 5000T / J of methanol.
- a unit of 5000T / J of methanol has a synthesis gas manufacturing section of the same size as a unit of 5000 million Nm3 / year of hydrogen.
- the gas consumption is lower (165 MMSCFD instead of 223 MMSCFD) because the purge of the methanol reaction loop is practically enough to provide the calories necessary for reforming.
- the Atlas-Methanol Production Plant-Point Lisa-Trinidad and Tobago project (Ref 4 and Ref 5) is a MegaMethanol workshop built by Lurgi for 5000T / J of methanol at a cost of $ 400 million base 2004. This workshop reaches a capacity of 5400 t / d for a gas consumption of 175 MMSCFD in 2005. That is a cost of $ 500 million, current base, the amount is of the same order of magnitude as that extrapolated from the Oryx project.
- the price of natural gas is that of shale gas as it is given to the Henry hub, it fluctuates from $ 2 to $ 4 / MMBTU and we retain a high value of $ 3.5 / MMBTU which logically leads to a return on investment 25%, or 10.85 € / MWh PCS using an unfavorable exchange rate of 1.1 $ / €
- the variable cost includes the cost of raw materials (process gas, fuel gas, annualized load for catalysts and adsorbents) and utilities (water cooling, demineralised water, electricity, nitrogen) to which the steam credit must be deducted.
- the variable cost is 38.0 € / 1000 Nm3 of H2. Natural gas represents 90% of the cost of raw materials and utilities, which is very common for this type of unit.
- the fixed cost consists of direct fixed costs including operators, a supervisor, maintenance costs amounting to 3.5% of the investment of the conversion unit, laboratory costs as well as indirect fixed costs. amounting to 41% of direct costs. To these costs will be added the research costs, the cost of taxes and insurance, the headquarters and commercial expenses to obtain the amount of the fixed costs which is 11.1 € / 1000 Nm3 of H2.
- the cost price will be complete by including the depreciation over ten years and a return on investment of 25% per year very common in an industrial project, ie 52 € / 1000 Nm3 of H2.
- k is a characteristic coefficient of the pipe
- p is the density of the gas
- v is the velocity of the gas in the pipe.
- the ratio of pressure losses between natural gas and hydrogen is:
- Delta P hyd / Delta P gn (p hyd / p g ") * (v hyd / v gn ) 2
- An advantage of the shale hydrogen production process is that once the plants are built it can work partially with any cut from the petroleum refining process by installing a prereforming process. It can also partially be supplied with natural gas by any network.
- Reciprocally a shale gas supply of a coal gasification unit to produce synthesis gas and preferably hydrogen will separate the CO2 formed and thus sequester in the (or) shale gas drilling.
- Another advantage of this method is that it makes it possible to regulate the electricity network when the intermittent energy sources (wind and photovoltaic) produce high power by using the buffer capacities provided on the natural gas network to store the gas. shale.
- Carbon dioxide 11% forestry and other agricultural uses
- Methane 16% it comes for 67% of enteric fermentations and animal dung,
- N20 6.2% it comes from 81% of the crop with nitrogen fertilizers.
- the project consists of replacing oil and gas consumption with shale gas, since electricity production is already almost non-greenhouse gas generating and the quantities of coal used in France are specific uses ..
- a modern refinery can absorb heavy fuels. All of the listed products except heavy fuels can be converted to hydrogen and CO and thus to hydrogen by equipping the reforming of a Mega or a Giga plant with a prereformer that will convert the different cuts into a treatable mixture by the reformer.
- the main problem that requires a prereformer is the coking problem of the catalysts which is solved by installing two prereformers in parallel.
- Part of the uses are transport, electricity production, domestic uses (heating, cooking), industrial uses, those of chemistry (methanol, ammonia, ...) and polymers.
- a Mega plant produces 640500 Nm3 / h of hydrogen or 5.05 billion Nm3 / year of hydrogen, an annual power of 2250MW.
- the gas consumed corresponds to 2650 MWh PCS or 228.4 PET / h or 1.8 million PET per year.

- the present application thus relates to a continuous process for manufacturing hydrogen from shale gas (or shale oil) in which:
- the produced shale gas (or oil) is converted to hydrogen by catalytic steam reforming or by partial oxidation by oxygen from air in a Mega or Giga plant located nearby.
- the Mega plant has a capacity of 500 to 2250 MW, and typically 2250MW or in which the Giga plant has a capacity greater than 2250MW, and typically 4.5 GW (4500MW), the power being calculated from the PCS (higher heating value ) hydrogen.
- Hydrogen is used either directly in a power plant located on the site and (or) injected into a hydrogen pipeline, a hydrogen distribution network built for this purpose.
- the hydrogen pipeline is used to power either power plants equipped with combustion plants, gas turbines or high-power fuel cells, or distribution stations to supply motor vehicles and or semi-mounted frames - trailer.
- - shale gas (or oil) supplies a coal or lignite gasification plant producing synthesis gas and / or hydrogen and preferably hydrogen, shale gas is temporarily stored in the reservoirs planned on the natural gas network and this to allow the regulation of the electricity network when intermittent energy sources (wind and photovoltaic) produce high power.
- the conversion to hydrogen is carried out either by simple catalytic reforming, or double or by partial oxidation with oxygen in the air, or preferably by autothermal reforming (reforming coupling and partial oxidation).
- the hydrogen conversion unit is equipped with a pre-reforming process for converting any petroleum fraction into synthesis gas and / or hydrogen.
- the conversion reactor can be partially supplied with natural gas from a natural gas network.
- the CO / H2 ratio of the synthesis gas is oriented towards the production of hydrogen in one or more consecutive transformation reactors.
- the decarbonated synthesis gas undergoes complementary treatments to separate the hydrogen to reach purities of between 96 and more than 99.9% hydrogen.
- the possible treatments are very numerous: PSA (pressure swing absorption on molecular sieves, anaerobic digestion, cryogenics, separation on membranes)
- the separated compounds CH4, CO2 and residual CO
- CH4, CO2 and residual CO can be recycled or injected into the borehole (s)
- other impurities nitrogen, for example
- - IMMBTU is equivalent to 1055.06 E6 J or 0.293 MWh Icubic feet / day is equivalent to 0.028 m3 / day
