Abstract
A low-concentration methane gas oxidation system includes: a single heat source device; and an oxidation device to oxidize low-concentration methane gas by using heat from the heat source device. The oxidation device includes a plurality of individual oxidation units including respective catalyst oxidizers. The individual oxidation units include: a first individual oxidation unit including a first catalyst oxidizer using heat of heat source gas from the heat source device, and a first heat exchanger to preheat low-concentration methane gas that flows into an additional catalyst oxidizer provided in a branching supply passage on downstream side, by using, as a heating medium, oxidized gas from the first catalyst oxidizer; and at least one additional individual oxidation unit including an additional catalyst oxidizer to oxidize low-concentration methane gas preheated by the first catalyst oxidizer or the additional catalyst oxidizer provided in a branching supply passage on upstream side.
