CATALYTIC DECOMPOSITION DEVICE AND INTEGRATED WASTE GAS TREATMENT SYSTEM
An integrated waste gas treatment system includes an adsorption/desorption device that receives a waste gas that includes an organic compound and an organic nitrogen compound exhausted from a semiconductor manufacturing facility, where the adsorption/desorption device adsorbs the organic compound and the organic nitrogen compound and concentrates and desorbs the organic compound and the organic nitrogen compound, and a catalytic decomposition device disposed adjacent to the adsorption/desorption device, where the catalytic decomposition device includes a catalytic chamber that provides a gas passage through which a gas desorbed from the adsorption/desorption device flows and an oxidation-reduction catalyst disposed in the gas passage that removes the organic compound and the organic nitrogen compound from the desorbed gas. The organic compound and the organic nitrogen compound are subjected to an oxidation treatment by the oxidation-reduction catalyst, and nitrogen oxides generated by the oxidation treatment are removed by a selective reduction reaction.
EVAPORATIVE FUEL VAPOR EMISSION CONTROL SYSTEMS
The present disclosure describes an evaporative emission control canister system that includes: one or more canisters comprising at least one vent-side particulate adsorbent volume comprising a particulate adsorbent having microscopic pores with a diameter of less than about 100 nm; macroscopic pores having a diameter of about 100 - 100,000 nm; and a ratio of a volume of the macroscopic pores to a volume of the microscopic pores that is greater than about 150%, and having a retentivity of about 1.0 g/dL or less. The system may further include a high butane working capacity adsorbent. The disclosure also describes a method for reducing emissions in an evaporative emission control system.
