An air purifying system includes: a carbon dioxide remover including first and second spaces partitioned by a gas permeable membrane with 50 nm or less diameter micropores; a feed passage leading to-be-purified air from a room to the first space; a supply passage supplying clean gas having lower carbon dioxide and higher oxygen concentrations than the to-be-purified air to the second space; a discharge passage discharging, from the second space, mixed gas; a return passage leading purified air from the first space into the room, the purified air resulting from removing carbon dioxide from the to-be-purified air; and adjusting equipment adjusting a gas pressure in the first and second spaces to be substantially equal to each other. The to-be-purified air flows in the first space along a surface of the gas permeable membrane, and the clean gas flows in the second space along a surface of the gas permeable membrane.

Air purifying system

A liquid having oxygen absorbing ability, comprising a cobalt-salen complex or a derivative thereof and an ionic liquid formed from an anion having an amine structure and a cation of an aliphatic quaternary phosphonium or ammonium having alkyl chains with each 2-20 carbon atoms, wherein the anion of the ionic liquid is coordinated to a cobalt ion of the cobalt-salen complex or a derivative thereof.

Liquid having oxygen absorbing ability, method for producing same, and complex solution containing same

A steam permselective membrane containing a crosslinked hydrophilic polymer is provided. The steam permselective membrane may further contain at least one alkali metal compound selected from the group consisting of a cesium compound, a potassium compound and a rubidium compound.

Steam permselective membrane, and method using same for separating steam from mixed gas

Disclosed is a COpermselective membranehaving an amino acid ionic liquid and a porous membrane impregnated with the amino acid ionic liquid, wherein the amino acid ionic liquid contains a certain range of water.

In a gas separation apparatus that separates carbon dioxide and water vapor from a first mixture gas containing at least carbon dioxide, nitrogen and water vapor, the energy utilization efficiency thereof is improved. The gas separation apparatus is constructed to include a first separation membraneand a second separation membranethat are made of different materials. When the first mixture gas is supplied, the first separation membraneseparates a second mixture gas containing carbon dioxide and water vapor that permeate through the first separation membrane by allowing carbon dioxide and water vapor to permeate selectively. When the second mixture gas is supplied, the second separation membraneseparates water vapor that permeates through the second separation membraneby allowing water vapor to permeate selectively.

Gas separation apparatus, membrane reactor, and hydrogen production apparatus

In a gas separation apparatus that separates carbon dioxide and water vapor from a first mixture gas containing a predetermined major component gas, carbon dioxide, and water vapor, the energy utilization efficiency thereof is improved. Also, by utilizing the function of this gas separation apparatus, a membrane reactor and a hydrogen production apparatus exhibiting high energy utilization efficiency are provided. The gas separation apparatus is constructed to include a first separation membraneand a second separation membranethat are made of different materials. When the first mixture gas is supplied at a temperature of 100&#xb0; C. or higher, the first separation membraneseparates a second mixture gas containing carbon dioxide and water vapor that permeate through the first separation membrane by allowing carbon dioxide and water vapor to permeate selectively. When the second mixture gas is supplied, the second separation membraneseparates water vapor that permeates through the second separation membraneby allowing water vapor to permeate selectively.
