Abstract
A pressure-reducing sampling apparatus includes a primary pressure chamber for receiving a pressurized fluid from a pressurized component and including a liquid outlet for collecting a sample of a liquid from the pressurized fluid in the primary pressure chamber, one or more secondary pressure chambers in fluid communication with the primary pressure chamber to receive and store a gas received from the primary pressure chamber, and a vent in fluid communication with a final secondary pressure chamber of the one or more secondary pressure chambers and configured to vent the gas from the final secondary pressure chamber.
Claims15
A pressure-reducing sampling apparatus, comprising:
- a primary pressure chamber for receiving a pressurized fluid from a pressurized component and including a liquid outlet for collecting a liquid sample from the pressurized fluid in the primary pressure chamber;
- one or more secondary pressure chambers in fluid communication with the primary pressure chamber to receive and store a gas received from the primary pressure chamber;
- and
- a vent in fluid communication with a final secondary pressure chamber of the one or more secondary pressure chambers and configured to vent the gas from the final secondary pressure chamber.
A method, comprising:
- receiving a pressurized fluid from a pressurized system into a primary pressure chamber of a pressure-reducing sampling apparatus;
- testing a pressure of the primary pressure chamber via a pressure gauge;
- determining if the pressure of the primary pressure chamber exceeds a pre-determined threshold;
- discharging a gas derived from the pressurized fluid into a secondary pressure chamber in fluid communication with the primary pressure chamber when the pressure of the primary pressure chamber exceeds the pre-determined threshold;
- and
- collecting a sample of liquid from the pressurized fluid in the primary pressure chamber when the pressure of the primary pressure chamber is measured below the pre-determined threshold.
