LANDFILL GAS CONVERSION DEVICE APPLYING DIRECT CONVERSION TECHNOLOGY OF METHANE FROM LANDFILL GAS

摘要

The present invention relates to a landfill gas conversion apparatus employing a technology for directly converting methane of landfill gas. The apparatus includes: a landfill gas collection device which is installed on a landfill site and collects landfill gas; an inertia collision-type dust removal device which removes moisture and fine dust from the collected landfill gas; an ammonia and hydrogen sulfide removal device which removes at least one from ammonia and hydrogen sulfide from a first purified landfill gas, which is firstly purified by the inertia collision-type dust removal device; a siloxane removal device which removes siloxane from a second purified landfill gas, which is secondarily purified by the ammonia and hydrogen sulfide removal device; an oxygen removal device which removes oxygen from a third purified landfill gas, which is thirdly purified by the siloxane removal device; a nitrogen removal device which removes nitrogen from a fourth purified landfill gas, which is fourthly purified by the oxygen removal device; and a storage tank which stores a fifth purified landfill gas, which is fifthly purified by the nitrogen removal device.
