## Abstract

A bypass assembly is provided for preventing unwanted liquids from collecting within fuel gas risers, exiting such risers and contaminating fuel gas systems. A conduit extends from a riser vessel to a natural gas flow line. An insert extends from the bypass line into the natural gas flow line. As production flows through the flow line and insert, a suction force is created that draws liquids from the riser into the conduit and, ultimately, back into the flow line system.

## Claims

### Claim 1

A method for removing liquids from a fuel gas riser connected to a flow line comprising:
a. connecting a conduit having a first end and a second end, wherein said first end of said conduit is attached to said riser, and said second end of said conduit is attached to said flow line downstream of said riser;
b. applying a suction force to said conduit; and
c. transferring liquids from said riser to said flow line through said conduit.

### Claim 2 (depends on 1)

The method of claim 1, wherein said step of applying suction force to said conduit further comprises extending said second end of said conduit into said flow line.

### Claim 3 (depends on 2)

The method of claim 2, wherein said step of extending said second end of said conduit into said flow line further comprises connecting an insert member to said second end of said conduit, wherein at least a portion of said insert member is positioned in said flow line.

### Claim 4 (depends on 3)

The method of claim 3, wherein said insert member further comprises a substantially tubular member having a first end, a second end and a curved section between said first and second ends.

### Claim 5

An apparatus for removing liquids from a fuel gas riser connected to a flow line comprising:
a. a conduit having a first end and a second end, wherein said first end is connected to said riser and said second end is connected to said flow line downstream of said riser; and
b. a substantially tubular insert having a first end, a second end and openings at said first and second ends, wherein said first end of said insert is connected to said second end of said conduit, and said second end of said insert extends into said flow line.

### Claim 6 (depends on 5)

The apparatus of claim 5, wherein said substantially tubular insert is curved between said first and second ends, and the opening at said second end of said insert is oriented substantially away from said riser.

### Claim 7 (depends on 6)

The apparatus of claim 6, wherein said substantially tubular insert further comprises at least one aperture between said first and second ends, wherein a portion of said at least one aperture is vertically aligned with a portion of said opening at the second end of said insert.
