ABSTRACT:
A method for the disposal of waste gas, which method comprises (a) heating the incoming waste gas containing hydrocarbons, carbon monoxide, and other inflammable organic compounds with the gas obtained by removing heat from the outlet gas of the catalytic-oxidation reactor, (b) further heating the resultant hot waste gas with part of the outlet gas of the catalytic-oxidation reactor, (c) subjecting the heated waste gas to complete oxidation in the catalytic-oxidation reactor thereby rendering the waste gas no longer noxious, (d) diverting part of the outlet gas of the catalytic-oxidation reactor to be used for heating the aforementioned heated waste gas, (e) causing at least part of the outlet gas of the reactor which has been used for heating the waste gas to mingle with the remainder of the outlet gas of the reactor, (f) causing the remainder of the outlet gas of the reactor which has been used for heating the waste gas to mingle with the aforementioned heated waste gas, and (g) subjecting to heat recovery the mixture of the remainder of the outlet gas of the reactor with at least part of the outlet gas of the reactor which has been used for heating the waste gas.
