Abstract

The present invention provides a gas pressurized separation system to strip a product gas from a liquid stream and yield a high pressure gaseous effluent containing the product gas. The system comprises a gas pressurized stripping apparatus, such as a column, with at least one first inlet allowing flow of one or more liquid streams in a first direction and at least one second inlet allowing flow of one or more high pressure gas streams in a second direction, to strip the product gas into the high pressure gas stream and yield through at least one outlet a high pressure gaseous effluent containing the product gas; and two or more heat supplying apparatuses provided at different locations along the column. Processes for separating a product gas from a gaseous mixture to yield a high pressure gaseous effluent containing the product gas, utilize the gas pressurized separation system described above.

Claims

1. A gas pressurized separation system to strip a product gas from a liquid stream to yield a gaseous effluent that contains the product gas, the system comprising:

(a) a gas pressurized stripping apparatus with at least one liquid inlet allowing flow of one or more liquid streams into the apparatus and at least one stripping gas inlet allowing flow of one or more stripping gas streams into the apparatus, wherein each stripping gas stream is separate and independent from the liquid streams and separate and independent from by-products of the liquid streams, and wherein the stripping gas streams are configured to strip the product gas into the stripping gas streams and yield through at least one outlet a gaseous effluent that contains the product gas; and

(b) heat supply apparatuses allowing for independent control of temperature along the gas pressurized stripping apparatus at locations between the at least one liquid inlet allowing flow of one or more liquid streams into the apparatus and the at least one stripping gas inlet allowing flow of one or more gas streams into the apparatus.

2. The gas pressurized separation system of claim 1, wherein the heat supplying apparatuses provide heat at two or more different locations along the gas pressurized stripping apparatus and are connected to each other.

3. The gas pressurized separation system of claim 1, wherein the heat supplying apparatuses provide heat at two or more different locations along the gas pressurized stripping apparatus and are separate from each other.

4. The gas pressurized separation system of claim 1, wherein the heat supplying apparatuses provide heat at two or more different locations along the column and are internal to the gas pressurized stripping apparatus.

5. The gas pressurized separation system of claim 1, wherein the heat supplying apparatuses provide heat at two or more different locations along the column and are external to the gas pressurized stripping apparatus.

6. The gas pressurized separation system of claim 1, wherein heat is provided through the high pressure stripping gas streams and wherein the stripping gas inlet allows for flow of one or more stripping gas streams at a pressure of at least 4 atm.

7. A gas pressurized separation system to strip a product gas from a liquid stream to yield a high pressure gaseous effluent that contains the product gas, the system comprising:

(a) a gas pressurized stripping apparatus with a liquid stream inlet and a high pressure gas stream inlet, wherein the high pressure gas stream entering at the high pressure gas stream inlet is separate and independent from the liquid stream entering at the liquid stream inlet and separate and independent from by-products of the liquid stream, and wherein the high pressure gas stream is configured to strip the product gas into the high pressure gas stream and yield a high pressure gaseous effluent that contains the product gas at an outlet; and

(b) heat supply apparatuses allowing for independent control of temperature along the gas pressurized stripping apparatus at locations between the high pressure gas stream inlet and the liquid stream inlet.

8. The gas pressurized separation system of claim 7, wherein the heat supplying apparatuses provide heat at two or more different locations along the gas pressurized stripping apparatus and are connected to each other.

9. The gas pressurized separation system of claim 7, wherein the heat supplying apparatuses provide heat at two or more different locations along the gas pressurized stripping apparatus and are separate from each other.

10. The gas pressurized separation system of claim 7, wherein the heat supplying apparatuses provide heat at two or more different locations along the column and are internal to the gas pressurized stripping apparatus.

11. The gas pressurized separation system of claim 7, wherein the heat supplying apparatuses provide heat at two or more different locations along the column and are external to the gas pressurized stripping apparatus.

12. The gas pressurized separation system of claim 7, wherein the high pressure gas stream inlet allows for flow of the high pressure gas stream at a pressure of at least 4 atm.

13. A gas pressurized separation system to strip a product gas from a liquid stream to yield a high pressure gaseous effluent that contains the product gas, the system comprising:

(a) a gas pressurized stripping apparatus with at least one liquid stream inlet allowing flow of one or more liquid streams into the apparatus and at least one high pressure gas stream inlet allowing flow of one or more high pressure gas streams into the apparatus at a pressure of at least 4 atm, wherein each high pressure gas stream is separate and independent from the liquid streams and by-products of the liquid streams, and wherein each high pressure gas stream is configured to strip the product gas into the high pressure gas stream and yield a high pressure gaseous effluent that contains the product gas through at least one outlet; and

(b) heat supply apparatuses allowing for independent control of temperature along the gas pressurized stripping apparatus at locations between the liquid stream inlet allowing flow of one or more liquid streams into the apparatus and the at least one high pressure gas stream inlet allowing flow of one or more high pressure gas streams into the apparatus.

14. The gas pressurized separation system of claim 13, wherein the heat supplying apparatuses provide heat at two or more different locations along the gas pressurized stripping apparatus and are connected to each other.

15. The gas pressurized separation system of claim 13, wherein the heat supplying apparatuses provide heat at two or more different locations along the gas pressurized stripping apparatus and are separate from each other.

16. The gas pressurized separation system of claim 13, wherein the heat supplying apparatuses provide heat at two or more different locations along the column and are internal to the gas pressurized stripping apparatus.

17. The gas pressurized separation system of claim 13, wherein the heat supplying apparatuses provide heat at two or more different locations along the column and are external to the gas pressurized stripping apparatus.
