Abstract

A hydrocarbon production apparatus that removes debris from a hydrocarbon fluid is described. The apparatus includes a first conduit, a second conduit, a valve, and at least one baffle. The first conduit includes an inlet, an outlet, and a flow path that extends between the inlet and the outlet. The flow path can receive a flow of a hydrocarbon fluid, which includes debris, from the inlet and direct the hydrocarbon fluid from the inlet to the outlet. The second conduit includes a debris receptacle. The valve is fluidly coupled to the second conduit and can isolate the debris receptacle from the flow path of the first conduit and at least a portion of the second conduit. The at least one baffle is oriented to direct at least a portion of the debris from the flow path of the first conduit to the second conduit.

First claim

What is claimed is:

1. A method for removing debris from a hydrocarbon fluid flow stream, comprising:
receiving a flow of a hydrocarbon fluid that comprises debris into an inlet of a first conduit that comprises a flow path that extends between the inlet and an outlet of the first conduit;
separating at least a portion of the debris from the hydrocarbon fluid with a first baffle that is coupled to a first portion of an inner surface of the first conduit between the inlet and the outlet, the first baffle comprising a first dimension that is a vertical projection of the first baffle orthogonal to a longitudinal axis of the first conduit;
separating at least a portion of the debris from the hydrocarbon fluid with a second baffle coupled to a second portion of the inner surface of the first conduit between the inlet and the outlet, the second baffle comprising a second dimension that is a vertical projection of the second baffle orthogonal to the longitudinal axis of the first conduit, a sum of the first and second dimensions equal to or less than a diameter of the first conduit;
directing, based at least in part on the orientation of the first and second baffles, the separated debris from the flow path of the first conduit into a flow path of a second conduit;
directing the separated debris from the flow path of the second conduit into a debris receptacle of the second conduit that is angularly connected to the first conduit between the inlet and the outlet;
fluidly isolating the debris receptacle from the flow path of the first conduit and at least a portion of the flow path of the second conduit; and
subsequent to fluidly isolating the debris receptacle, removing the portion of separated debris from the debris receptacle.

2. The method of claim 1 , wherein isolating the debris receptacle comprises closing a valve fluidly coupled to the second conduit.

3. The method of claim 1 , wherein removing the separated debris comprises:
bleeding a portion of a fluid from the receptacle to reduce pressure within the receptacle;
verifying the pressure within the receptacle;
disconnecting the receptacle; and
removing the separated debris and a remaining portion of the fluid from the receptacle.

4. The method of claim 3 , wherein bleeding the portion of the fluid from the receptacle comprises opening a bleed valve.

5. The method of claim 1 , further comprising directing the separated debris from the flow path of the first conduit to the flow path of the second conduit at an angle of 90 degrees or less.

6. The method of claim 5 , wherein isolating the debris receptacle comprises closing a valve fluidly coupled to the second conduit.

7. The method of claim 5 , wherein removing the separated debris comprises:
bleeding a portion of a fluid from the receptacle to reduce pressure within the receptacle;
verifying the pressure within the receptacle;
disconnecting the receptacle; and
removing the separated debris and a remaining portion of the fluid from the receptacle.

8. The method of claim 7 , wherein bleeding the portion of the fluid from the receptacle comprises opening a bleed valve.

9. The method of claim 1 , wherein the at least one baffle is coupled to the inner surface of the first conduit at an angle of 90 degrees or less.

10. The method of claim 1 , wherein a perpendicular distance between a tip of the at least one baffle and the inner surface of the first conduit is approximately half of a diameter of the first conduit or longer.

11. The method of claim 1 , wherein a perpendicular distance between a tip of the second baffle and the inner surface of the first conduit is approximately half of a diameter of the first conduit or longer.

12. The method of claim 1 , wherein an axial distance between the tip of the first baffle and a tip of the second baffle is approximately half of a diameter of the first conduit or longer.

13. The method of claim 1 , wherein the second baffle is coupled to the inner surface of the first conduit at an angle of 90 degrees or less.
