A PROCESS FOR THE PURIFYING OF A RAW GAS STREAM CONTAINING MAINLY C1 -C5 HYDROCARBONS AND CARBON DIOXIDE, AND IMPURITIES OF ORGANIC AND INORGANIC SULFUR COMPOUNDS, HALOGENATED AND NON-HALOGENATED VOLATILE ORGANIC COMPOUNDS AND OXYGEN
A PROCESS FOR THE PURIFYING OF A RAW GAS STREAM CONTAINING MAINLY C1 -C5 HYDROCARBONS AND CARBON DIOXIDE, AND IMPURITIES OF ORGANIC AND INORGANIC SULFUR COMPOUNDS, HALOGENATED AND NON-HALOGENATED VOLATILE ORGANIC COMPOUNDS AND OXYGEN
A method for the purification of a raw gas stream by selective catalytic oxidation, in which organic and inorganic sulfur compounds, halogenated and non-halogenated volatile organic compounds are selectively oxidized without substantially oxidizing the lower hydrocarbons and the sulfur containing compounds present in the gas to sulfur trioxide and excess of oxygen is removed by oxidation of lower alcohols, ethers or hydrogen added to the raw gas stream upstream the catalytic oxidation.
