摘要： An ethylene oxide gas removal method of the present invention is a method for removing ethylene oxide gas emitted into a predetermined partition space (12), and the method includes: a first step of suctioning EO-containing air (CA) that contains ethylene oxide emitted into the partition space (12) and supplying the EO-containing air (CA) to a concentration device (14); a second step of removing a water content from the suctioned EO-containing air (CA), and thereafter adsorbing and concentrating ethylene oxide by an adsorbing material (42), in the concentration device (14); a third step of desorbing the concentrated ethylene oxide from the adsorbing material (42) and sending the ethylene oxide to a removal device (16); and a fourth step of decomposing and removing ethylene oxide gas by the removal device (16).
