Abstract

A gas production line including: an inlet; an outlet; and a wet gas condenser connected between the inlet and the outlet, wherein the wet gas condenser includes: a condensing chamber; a condensing surface; and a collecting chamber, wherein, in use, water vapour in wet gas passing over the condensing surface is condensed into liquid water, the liquid water flowing along a predetermined flow path into the collecting chamber.

First claim

What is claimed is:

1. A gas production line comprising:
an inlet;
an outlet; and
a wet gas condenser connected between the inlet and the outlet, wherein the wet gas condenser comprises:
a pump;
a condensing chamber;
a condensing surface;
a collecting chamber; and
a water sensor attached to a wall of the collecting chamber,
wherein the water sensor is in communication with control circuitry to activate and deactivate the pump,
wherein, in use, water vapour in wet gas passing over the condensing surface is condensed into liquid water,
the liquid water flowing along a predetermined flow path into the collecting chamber.

2. The gas production line according to claim 1 , wherein the condensing surface extends through a wall of the condensing chamber to be in thermal contact with the environment outside the condensing chamber.

3. The gas production line according to claim 1 , wherein the pump is operable to pump water from the collecting chamber to a further location.

4. The gas production line according to claim 1 , wherein the control circuitry is configured to activate the pump when the water sensor detects the presence of water in its proximate area.

5. The gas production line according to claim 4 , wherein the condenser comprises a second water sensor attached to a wall of the collecting chamber.

6. The gas production line according to claim 5 , wherein the second water sensor is in communication with the control circuitry.

7. The gas production line according to claim 6 , wherein the control circuitry is configured to deactivate the pump when the second water sensor detects the absence of water in its proximate area.

8. The gas production line according to claim 1 , wherein the control circuitry is located in a subsea electronics module.

9. The gas production line according claim 1 , wherein the control circuitry is located in a topside control station.

10. The gas production line according to claim 1 , wherein the gas production line is used in a hydrocarbon extraction facility.

11. A method of removing water vapour from a wet gas flow in a gas production line, the method comprising:
providing a wet gas condenser comprising a pump, a condensing chamber, a condensing surface, a collecting chamber, and a water sensor attached to a wall of the collecting chamber, wherein the water sensor is in communication with control circuitry to activate and deactivate the pump;
connecting an inlet of the gas production line to the wet gas condenser;
connecting an outlet of the gas production line to the wet gas condenser; and
arranging the wet gas condenser such that water vapour in wet gas passing over the condensing surface is condensed into liquid water, the liquid water flowing along a predetermined flow path into the collecting chamber.

12. The method according to claim 11 , wherein the condensing surface extends through a wall of the condensing chamber to be in thermal contact with the environment outside the condensing chamber.

13. The method according to claim 11 , wherein the pump is operable to pump water from the collecting chamber to a further location.

14. The method according to claim 11 , wherein the control circuitry is configured to activate the pump when the water sensor detects the presence of water in its proximate area.

15. The method according to claim 14 , wherein the condenser comprises a second water sensor attached to a wall of the collecting chamber.

16. The method according to claim 15 , wherein the second water sensor is in communication with the control circuitry.

17. The method according to claim 16 , wherein the control circuitry is configured to deactivate the pump when the second water sensor detects the absence of water in its proximate area.

18. The method according to claim 11 , wherein the control circuitry is located in a subsea electronics module.

19. The method according to claim 11 , wherein the control circuitry is located in a topside control station.

20. The method according to claim 11 performed in an underwater hydrocarbon extraction facility.
