Definitions

  • the invention relates to a device for generating electricity from natural gas, comprising: a first and a second compartment, wherein the first compartment comprises an anode surface and the second compartment comprises a cathode surface electrically connected to the anode surface; a natural gas supply discharging in the first compartment; an oxidant supply discharging in the second compartment; and a third compartment connected to the first compartment for after burning gas from the first compartment.
  • Such a device is known from EP-A-1 025 604. Such a device is particularly used near a well which produces hydrocarbon fluids from an underground reservoir.
  • the gas which is discharged by the device and comprises substantially carbon dioxide, is compressed and injected into the underground reservoir. This reduces the exhaust of carbon dioxide into the atmosphere.
  • This object is achieved by the invention with a device according to the preamble, which is characterized by an oxygen supply discharging in the third compartment.
  • This oxygen is used for afterburning the gas, which is discharged by the first compartment and which comprises carbon monoxide, hydrogen and unburned natural gas.
  • these components are combusted without addition of nitrogen, such that the resulting gas is easily condensable for injection into a receptacle, such as an underground reservoir.
  • the device according to the invention comprises a cryogenic oxygen separation device, which supplies oxygen to the third compartment.
  • a cryogenic process involves high costs and reduces the electrical efficiency, only about 15% of the natural gas has to be oxydized using this pure oxygen, which reduces the disadvantages of such a cryogenic process.
  • the cryogenic process has the advantage that it could be built on a large scale without substantial difficulties.
  • the device comprises a fuel cell.
  • This fuel cell comprises the first and second compartment with the anode and cathode surfaces .
  • the invention also relates to a method for generating electricity from natural gas using a device according to the invention, which method comprises the steps of: - converting at the anode surface the natural gas to hydrogen and carbon monoxide and allowing the cathode and anode reactions to take place to produce a potential difference between anode surface and cathode surface, wherein an anode off-gas is produced, which comprises water and carbon dioxide; feeding the anode off-gas from the first compartment to the third compartment; supplying oxygen to the third compartment for after burning components of the anode off-gas.
  • the method comprises the steps of: - cooling air to a temperature at which oxygen condenses; separating the condensed oxygen; and supplying the condensed oxygen to the third compartment .
  • the nitrogen, which condenses at a lower temperature than oxygen, is removed, such that it will not come into the gas discharging from the third compartment .
  • the drawing shows a schematic representation of a device according to the invention.
  • the device 1 shown in the drawing comprises a first compartment 2 into which fuel cell tubes 3 extend.
  • the fuel cell tubes 3 are connected to a second compartment 4 having an inlet 5 and an outlet 6. Air is supplied to the inlet 5 and circulated through the fuel cell tubes 3 to the outlet 6.
  • the first compartment 2 has an inlet 7 to which the natural gas comprising methane is supplied.
  • the fuel cell tubes 3 convert the methane and the oxygen to carbon dioxide and water while producing electricity.
  • a mixture of this carbon dioxide, water and unburned natural gas and intermediate products discharge into a third compartment 8 through openings 9.
  • An oxygen supply conduit 10 also discharges into this third compartment 8. The oxygen provides for and after burning effect resulting in an off-gas comprising substantially carbon dioxide and water.
  • the water is separated from the carbon dioxide and this carbon dioxide is condensed and preferably inserted into a reservoir.
  • the oxygen supplied by the conduit 10 originates preferably from a cryogenic separation device 11, which separates out of a stream of air 12, a stream of oxygen 10 and a stream of nitrogen 13.
