Description
PROCESS OF HYDROGEN PRODUCTION IN HYDROCARBON FIELDS WITHOUT GREENHOUSE EMISSIONS
Field of invention
The present invention relates to a production of hydrogen by hydrocarbon gas decomposition sub terrain in the field. Horizontal and deviated fractured wells drilled and completed with downhole tractors in natural gas or gas-oil field are to be used to produce hydrogen generated sub terrain by electromagnetic heating, catalytic cracking and thermal plasma processes.
Background of the invention
Significant reserves of natural gas in the world are accumulated in tight, shale, depleted non-commercial gas fields.
A process which can decompose hydrocarbon gas to hydrogen and elemental carbon in hydrocarbon gas fields, may open access to an immense clean energy source. Decomposition of natural gas at high temperature allows producing hydrogen without generation and emissions of greenhouse gases.
The methane cracking at temperatures higher than 1000°C is an endothermic reaction:
CH4 C + 2H2 DH = +75 kJ/mol
In the presence of catalysts cracking reactions can occur at lower temperatures, in the range of 500-600°C.
Microwave heating involves electromagnetic waves and heat transfer. Microwaves are non-ionising electromagnetic radiation with wavelength of 1 mm - 1 m and frequency 300 MHz - 3000 GHz. Fluctuating electric and magnetic fields propagate as waves of electromagnetic radiation. Molecules of water and many other substances are electric dipoles. They have a partial positive charge at one end and a partial negative charge at the other. Alternating time-varying electric field of the microwaves make dipolar molecules oscillate back and forth, to rotate in orderto align accordingly. Rotating molecules hit other molecules and put them into motion, thus dispersing energy raises the temperature in solids and liquids. Materials exposed to electromagnetic radiation get heated up.
Maxwell's equations describe how electric and magnetic fields are generated by charges, currents, and changes of the fields. Faraday’s law of induction and Ampere’s law with Maxwell’s extension are:
V x E = - dB /dt
V x H = - dD /dt + J where:
E- electric field, volt per meter (meter? Then you should change all of those below. It’s meter in english).
B - magnetic flux density also called the magnetic induction, tesla, or equivalently, weber per square meter.
H - magnetic field strength, ampere per meter.
D - electric displacement field, coulomb per square meter.
J - current density, ampere per square meter.
The dielectric properties of materials are generally expressed using the relative permittivity e0e,·.
D = EcBr E where: eo ~ vacuum permittivity or dielectric constant,
£r - relative permittivity.
The microwave energy is weakened when propagating through a dielectric material. Microwave energy being absorbed will provide for electromagnetic heating of saturated reservoir rocks allowing to achieve required for hydrocarbon pyrolysis and methane decompositions temperature conditions.
Invention
This invention relates to a process of producing hydrogen from hydrocarbon fields using methane decomposition by pyrolysis and catalytic cracking achieved by applying microwave electromagnetic radiation to the saturated reservoir rock through multi-stage fractured horizontal and deviated wells.
A natural gas field 1 is drilled with horizontal or deviated well 2 and vertical production well 3 (Figure 1). Well 2 has a high-power electromagnetic microwave generator 4, a mobile unit, installed near the well site on the field surface. Through transmission wire lines 5 installed in the well microwaves are sent to the bottom- hole waveguides antennas 8 in the horizontal section of the well 2. Microwave generation tubes or irons can also be installed downhole. The temperature in the hydrocarbon gas-containing zone is raised when microwave energy is adsorbed in dielectric heating. Methane pyrolysis reactions are taking place in the near well bore area in the horizontal section of the well 2 heated up by electromagnetic irradiation process. Well 2 can be a multi-stage fractured horizontal well, completed to allow downhole tractors to move electromagnetic wave guide antennas along the horizontal wellbore. The downhole tractors are usually designed to fit in as an integral part of a downhole assembly using the same surface deployment equipment as for standard well operation.
Metal catalyst particles can be injected in the e-fractures together with proppant to allow methane decomposition and catalytic cracking to hydrogen 7 and carbon 8 to take place at lower temperatures (500-600°C). Produced solid carbon 8 accumulates in the near well bore areas, fractures and horizontal well bore.
The transmission wire lines 9 (E-line) are used to transfer electricity and electromagnetic waves to the bottom hole assembly in the well 2, Figure 2. The bottom-hole assembly in the horizontal section of the well includes waveguide antennas 10, downhole tractor 11 , compensator and emergency release device 12, electric motor 13 of the downhole tractor.
The fractures 14 in the well can be filled in with proppant and metal particles of catalyst. Nickel particles, or nickel in combination with aluminum, can be used as active catalysts in methane catalytic cracking process in the fractures and near well bore area. Cobalt and iron can also be used as catalyst for methane catalytic cracking.
Plasma pyrolysis process with generation of hydrogen 7 and carbon 8 is taking place around waveguide antennas in the fractures, near and in the well bore. Produced pure solid carbon will be gradually filling in the well bore. Downhole tractors 11 are used to pull and move the microwave waveguide antennas along the horizontal wellbore section of the well 2, Figure 3. Carbon can be washed out to the surface at a late stage of the process in order to be used for production of advanced carbon products like graphene and/or activated carbon.
In any of the embodiments described above, hydrogen produced from methane flux from the reservoir into a perforated and/or fractured intervals of well 2 and near well zones may be evacuated from the reaction areas through the wellbore of the well 2. Hydrogen generated in situ and segregated gravitationally upwards in the reservoir can also be produced by dedicated production well 3 from the crest of the geological field structure (Figure 1).
This microwave plasma technology invention enabies to implement a modular, small-scale and low-capital methane decomposition process in situ.
Decomposition of natural gas in situ of the hydrocarbon field represents a method to decarbonize a fossil fuel in a transition to hydrogen economy, cleaner and lower-cost advanced carbon products.
