METHOD OF REMOVING VOC FROM VOC-IMPREGNATED MATERIAL

摘要

[PROBLEMS] To remove VOCs and odor from a VOC-impregnated material placed in a treatment space safely at low cost without detriment to interior members and installations by carrying out a humidity control. [MEANS FOR SOLVING PROBLEMS] The method comprises the humidification step of humidifying the interior of a treatment space for VOC removal to a high level such that the interior is held unsaturated to thereby cause any VOCs retained by a material through adsorption or impregnation to form hydration complexes with generated water molecules of gaseous phase state, and the second step of reducing the humidity to thereby cause any VOC hydration complexes formed within the VOCs as a result of the humidification step to diffuse from the VOC-impregnated material into the treatment space.
