Abstract
In a method for removing methane from feed gas having a methane concentration of 2 mole % or less, the feed gas is optionally mixed with make-up methane or air and passed through a heat exchanger to heat the gas to an oxidation reactor inlet temperature T. The heated stream is passed to the reactor where the methane is oxidised. A gas stream including the products of the oxidation reaction are removed with the gas stream being at a reactor outlet temperature Thigher than the inlet temperature T. The gas stream is then passed through the heat exchanger against the reactor stream to recover heat from the gas stream removed in the reactor and to heat the reactor stream. The outlet temperature Tis measured and the inlet temperature Tis controlled by adjusting the relative amount of make-up methane and/or air added to the feed gas.
