Abstract
A method is described for treating a gas stream containing a flammable gas, such as hydrogen or a hydrocarbon gas. The gas stream is conveyed to a liquid ring pump (18), to which a gaseous oxidant and water are supplied. The water and the gas stream are discharged from the pump (18), with the discharged gas stream being subsequently separated from the liquid, and conveyed to a pyrolysis device (42) for pyrolysing the flammable gas and the oxidant. Any particulates and acidic species within the gas stream are retained by the water within the liquid ring pump to inhibit corrosion or blockage of the pyrolysis device (42). A filter or other device (40) may be provided to remove water from the gas stream before it enters the pyrolysis device (42).
