Abstract:
PROBLEM TO BE SOLVED: To provide an air cleaning system with a long-life cleaning unit, capable of performing a series of operation within a single unit. SOLUTION: Air to be treated is caused to pass through a rough water trap, half-dried, and then caused to pass through an adsorption column 150 (1) for dehydration and complete removal of carbon dioxide. Carbon monoxide and hydrocarbon in the air are oxidized and removed with the use of an oxidation catalyst (200). Water and carbon dioxide generated by the oxidation catalyst are removed with the use of an adsorption column 150 (2). COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
A gas purification system includes a gas purification unit and one or more safety devices. The gas purification unit includes an enclosure containing a purification material that exhibits an exothermic reaction when exposed to certain gas contaminants. The gas purification unit also has an inlet coupled to an unpurified gas inlet line and an outlet coupled to a purified gas outlet line. A safety device can be coupled either to the unpurified gas input line or the purified output line, or both, and develops an alarm signal when gas contaminants exceed a given concentration level for a period of time.

Abstract:
The invention teaches a purification system which uses a series of operations, in a single unit, to purify air, while extending the life of the purification units. Air is passed through a coarse water trap to remove liquid. The semi-dry air, is then passed through adsorbers, which remove the remaining moisture and all the carbon dioxide in a purification process. The present invention flows the air to be purified through adsorption columns twice, before and after passing the air through an oxygen catalyst unit. The flows of air are then rotated to a third column, which is thermally regenerating with the facilitation of a regeneration air supply from the purified air.

Abstract:
The invention teaches a purification system which uses a series of operations, in a single unit, to purify air, while extending the life of the purification units. Air is passed through a coarse water trap to remove liquid. The semi-dry air, which is usually less than 3000 ppm of water vapor, is then passed through adsorbers, which remove the remaining moisture and all the carbon dioxide in a purification process. The drying of the air before passing it through the adsorbers allows for greatly improved efficiency of air purification and extends the life of both the oxygen catalyst and the adsorption columns. The present invention also flows the air to be purified through adsorption columns twice, before and after passing the air through an oxygen catalyst unit. The oxidizing catalyst, which is heated to a temperature of approximately 300 degrees centigrade, converts carbon monoxide and hydrocarbons to H2O and CO2. The newly converted H2O and CO2 are then removed by the second pass through a second adsorption column in the second flow direction or downstream. The flows of air are then rotated with a third column, which is thermally regenerating with the facilitation of a regeneration air supply from the purified air.
