Title:
GENERATION METHOD, GENERATION APPARATUS, AND RECOVERY METHOD OF GASEOUS NITROGEN OXIDE
Document Type and Number:
Japanese Patent JP2014198336
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To oxidize, nitrify, or sterilize a target positioned within a storage cavity by using a nitrogen oxide.SOLUTION: A method comprises: a step of decompressing, by using a decompression device (3), a storage cavity (2) being retained in a hermetic state; a step of introducing a liquid nitrogen oxide into the storage cavity (2) abiding in a decompressed state or vacuum state from a storage tank (4) storing the liquid nitrogen oxide; and a step of gasifying, on an occasion for introducing the liquid nitrogen oxide into the storage cavity (2), at least a portion thereof by reducing the pressure of the nitrogen oxide to or below the threshold of the saturated vapor pressure curve thereof. The target (1) positioned within the storage cavity (2) can be oxidized, nitrified, or sterilized by the gaseous nitrogen oxide.
