초록 ▼

An apparatus for separation of gases from ambient air that has at least one separation column with an inlet at a first end and an outlet at a second end, a buffer column having a single inlet at a first end, a vacuum pump, and a valve system that connects the vacuum pump to the outlet at the first end of the separation column, and that connects the outlet at the second end of separation column to the single inlet at the first end of the buffer column.

대표청구항 ▼

1. An apparatus for separation of gases from ambient air, the apparatus comprising: at least one separation column, the separation column containing an inlet at a first end and an outlet at a second end;a buffer column having an adsorbent with a high capacity for nitrogen adsorption, the buffer column comprising a single port;a vacuum pump;a valve system that connects the vacuum pump to the inlet at the first end of the separation column, and that connects the outlet at the second end of separation column to the single port of the buffer column simultaneously. 2. The apparatus of claim 1 wherein the at least one separation column and buffer column contain an adsorbent having a total combined volume of less than 500 cc. 3. The apparatus of claim 1 wherein the vacuum pump operates at a pressure of about 0.08 atm to about 1.0 atm. 4. The apparatus of claim 1 further comprising: a battery pack connected to the separator for providing power to operate the separator and valve system. 5. The apparatus of claim 1 further comprising a plurality of separations columns, each of the columns containing an inlet at a first end and an outlet at a second end, and wherein the valve system connects the vacuum pump to the inlet at the first end of each of the plurality of separation columns, and that connects the outlet at the second end of each of the plurality of separation column to the single port of the buffer column. 6. A method of separating ambient air to obtain a stream of oxygen rich gas, the method comprising the steps: 1) evacuating a separation column to a first pressure through a feed end of a column;2) metering a flow of gas from a last in/first out (LIFO) buffer column having an adsorbent with a high capacity for nitrogen adsorption into a product end of the separation column while continuing to evacuate the column to a second pressure;3) stopping evacuation of the column while continuing the flow of gas from the LIFO buffer column at a second flow rate until a third pressure is reached in the separation column;4) pressurizing the separation column with ambient air through the feed end to a pressure of about 1 atm; and5) feeding air into the feed end of the column while drawing an oxygen rich gas from the product end of the separation column; and6) repeating steps 1 through 5. 7. The method of claim 6 wherein step 5 further comprises: transferring some of the oxygen rich gas to the LIFO buffer column until the LIFO buffer column is pressurized to about 1 atm. 8. The method of claim 7 further comprising: feeding air into the separation column while collecting the oxygen rich gas from the product end of the column. 9. The method of claim 6 wherein the first, second, and third pressures are all less than 1 atm. 10. The method of claim 6 wherein the second pressure is 0.5 atm or less.
