An apparatus for removing concentrations of liquid from a natural gas pipeline comprising a tap valve mounted on the pipeline at the upper portion thereof so as to be in communication with the interior of the pipeline. A siphon apparatus is removably mounted on the tap valve and includes a siphon pipe which is vertically movably mounted with respect to the tap valve. The siphon pipe is vertically movable from an upper position wherein the lower end of the siphon pipe is positioned above the tap valve to a lower position wherein the siphon pipe extends through the tap valve so that the lower end of the siphon pipe is positioned at the bottom interior of the pipeline. A discharge pipe extends from the siphon pipe and is in communication with a liquid holding tank. A siphon valve is imposed in the discharge pipe to permit the selective removal of the liquid from the pipeline. A portion of the siphon pipe is enclosed by an operating cylinder barrel. A piston is positioned on the siphon tube and sealably engages the interior of the operating cylinder barrel. The upper and lower ends of the operating cylinder barrel are in communication with a source of pressure so that the siphon pipe may be raised or lowered by means of the pressure. The upper and lower ends of the operating cylinder barrel are also in communication with the atmosphere through valves to permit the venting of the operating cylinder barrel as desired.

The method of removing concentrations of liquid from a natural gas pipeline, comprising the steps of: (a) locating a concentration of liquid in the pipeline; (b) installing a valve means on said pipeline above the concentration of liquid; (c) creating an opening in said pipeline which communicates with the interior of said valve means; (d) mounting a removable secured hollow support means to said valve means, a vertically movable siphon pipe means being completely enclosed within said hollow support means; (e) supplying operating pressure to said siphon pipe means, from within the pipeline, thereby lowering said siphon pipe means through said valve means into the interior of said pipeline; (f) utilizing the pressure within the pipeline to force the liquid upwardly through said siphon pipe means to a receiving area remote from said siphon pipe means; (g) and supplying operating pressure to said siphon pipe means, from within the pipeline, thereby raising said siphon pipe means from the interior of said pipeline above said valve means to enable removable of said hollow support means.
