Abstract: The invention relates to a method as well as a device for separation of a carbon-dioxide-containing gas mixture (1), whereby carbon dioxide is separated from the carbon-dioxide-containing gas mixture (1) by physical gas washing (W1) and is converted into two product streams (3, 4) that consist primarily of carbon dioxide and have different pressures, and in the event of an operational breakdown, after their pressures are balanced, the product streams are subjected to an after-treatment step (W2) and then are released into the atmosphere. For balancing the pressures of the two carbon dioxide product streams (3, 4), the carbon dioxide stream (3, 7) that has the lower pressure is compressed by a gas jet ventilator (G), whereby the carbon dioxide stream (4) that has the higher pressure is used as a pumping medium (6).

Abstract: The portable air purification device provides extreme portability such that the device can be placed virtually anywhere desired. Should an area need the device, one person can easily transport as needed. Also important is the separability of the vacuum canister and filtration canister. Often it may be advantageous to place the vacuum canister strategically, and the filtration canister supplying purified air in another location. The device provides for such via the separate canisters and the transfer hose, which can be almost any length needed. The device uses liquid filtration media, solid filtration media, and a HEPA filter.

Abstract: An adsorbent canister has a housing defining an adsorption chamber therein, an adsorbent filled in the adsorption chamber, and a honeycomb core. The honeycomb core is made from a material having a higher thermal conductivity than the adsorbent, defines therein a plurality of cells passing through the honeycomb core and is disposed in the adsorption chamber. The adsorbent canister can further have a heater for heating the honeycomb core or the honeycomb core can be made from a material, which produce heat when current is applied.

Abstract: A canister for trapping a fuel vapor vaporized in a fuel tank has a casing defining an adsorption chamber therein, an adsorbent capable of adsorbing the fuel vapor and filled in the adsorption chamber and a flow regulation plate disposed in the casing. The casing has a fuel introducing port configured to introduce the fuel vapor from the fuel tank into the adsorption chamber, and an air communicating port communicating the adsorption chamber with the atmosphere. The air communicating port is formed on a side surface of the casing extending in a direction of gravitational force. The flow regulation plate disposed at an end of the adsorption chamber near the air communicating port and has an opening configured to communicate the adsorption chamber with the air communicating port. The opening is positioned above the air communicating port in the direction of gravitational force.

Abstract: Water circulation systems with air stripping arrangements to treat and remove undesirable disinfectant byproducts from potable water in municipal water tanks, ponds, and other bodies of water. The systems include a flotation platform, dish, draft tube, and an impeller to draw water from the depths of the tank up through the draft tube to be discharged outwardly of the dish to create a primary circulation pattern and an induced, inner or secondary circulation pattern. Each system additionally includes an air stripping arrangement positioned adjacent and about the upper portion of the draft tube and adjacent an upper portion of the secondary flow. The air stripping arrangement includes a plurality of submerged sets of air manifolds wherein pressurized air is supplied to the air manifolds and driven out of them in bubbles to create a treatment zone immediately above each set of manifolds.

Abstract: Provided is a radon reduction apparatus for groundwater disinfection. The radon reduction apparatus includes an agitation space forming body that groundwater fed through a groundwater feed pipe passes through before inflow into the groundwater storage tank and that forms a water turbine installation space whose top portion is not filled with groundwater; a water turbine located in the water turbine installation space to be rotated by groundwater when the fed groundwater falls, is run against the bottom and scattered; an oxygen supply unit supplying oxygen to groundwater before inflow of the groundwater to the agitation space forming body; a ventilating fan rotated by receiving rotary power of the water turbine and connected to the water turbine installation space to discharge air of the water turbine installation space; and an antiseptic solution supply unit supplying antiseptic solution to be mixed with the groundwater.

Abstract: A process vessel is provided for separating a multi-component stream. The process vessel includes an inlet for permitting introduction of reaction water stream into the vessel and an outlet for withdrawing a water-rich phase from the vessel. The vessel further includes a plurality of draw-off points for drawing off a phase rich in suspended hydrocarbons from the vessel, the draw-off point(s) being located above the outlet.

Abstract: An acid gas absorbent comprising an alkylamino alkyloxy (alcohol) monoalkyl ether and a process for the selective removal Of H2S from gaseous mixtures containing H2S and CO2 using an absorbent solution comprising an alkylamino alkyloxy alcohol monoalkyl ether.

Abstract: An acid gas absorbent comprising a metal sulfonate, phosphonate or carboxylate of a hindered amine and a process for the selective removal Of H2S as well as other acidic components such as carbon disulfide, carbonyl sulfide and oxygen and sulfur derivatives of C1 to C4 hydrocarbons from mixtures containing such acidic components and CO2 using said absorbent.
