SULFIDE COMPOUND REMOVING AND METHANE AND CARBON DIOXIDE SEPARATING APPARATUS USING THE FE-EDTA

摘要

A device for removing sulfur compounds and separating methane and carbon dioxide by using a liquid phase iron chelate catalyst is provided to selectively remove ammonia, hydrogen sulfide and other odorous substances from gases generated in a landfill and purify methane and carbon dioxide to a high purity. A device for removing sulfur compounds and separating methane and carbon dioxide by using a liquid phase iron chelate catalyst comprises: a rectangular case type reactor body(90); a first partition(92) for dividing a first reactor(10) and a second reactor(20), and a third reactor(30) and a fourth reactor(40) with the first partition being spaced apart from a lower part(94) of the reactor body in a predetermined distance; a second partition(91) for dividing the first reactor and the second reactor; a third partition(93) for dividing the third reactor and the fourth reactor; a connecting plate(95) which connects lower ends of the second partition and the third partition to form a circulation path; a liquid phase iron chelate catalyst filled in the first reactor to the fourth reactor; a gas inlet(50) formed on a lower portion of the first reactor; a sulfur collection port(88) mounted on the lower plate; a methane collection port(80) formed in an upper part of the first and second reactors; an air inlet(60) formed in a lower portion of the third reactor; and a carbon dioxide collection port(85) formed in an upper part of the third and fourth reactors.
