Abstract
A purification arrangement for a gas pipeline system includes a pressure vessel and at least a modular separator assembly and a modular filter assembly in the interior of the pressure vessel. A gas flow may be established through the pressure vessel, and the gas may pass through the modular separator and filter assemblies to remove liquid and/or solid particulates from the gas.
Claims21
A purification arrangement for a gas pipeline system, the purification arrangement comprising:
- a pressure vessel including an interior, a gas inlet, and a gas outlet and defining a gas flow path through the interior of the pressure vessel between the gas inlet and the gas outlet, the pressure vessel having an elongate configuration including a horizontal axis and first and second axial ends and a cover moveably mounted to the first axial end, wherein the cover is movable between a first position wherein the cover is sealed to the first axial end of the pressure vessel and a second position wherein the cover provides an opening at the first axial end of the pressure vessel;
- a modular filter assembly removably located in the gas flow path in the interior of the pressure vessel and comprising a plurality of filter elements, each filter element having a filter medium positioned across the gas flow path to filter particulates from gas flowing through the filter element;
- and
- a modular separator assembly removably located in the gas flow path in the interior of the pressure vessel between the filter assembly and the gas inlet, wherein the modular separator assembly includes a transit mechanism and one or more separators positioned in the gas flow path to remove particulates from gas flowing along the gas flow path;
- wherein the modular filter assembly and modular separator assembly are each removable from and moveable into the pressure vessel as an integral unit, the modular separator assembly being removable from and moveable into the pressure vessel via the opening at the first axial end of the pressure vessel when the cover is in the second position and wherein the transit mechanism includes a plurality of wheels arranged to roll with the modular separator assembly along the interior of the pressure vessel through the opening in the axial end.

A method for removing particulates from a gas flowing in a gas pipeline system, the method comprising:
- establishing a flow of gas through the interior of a horizontal pressure vessel from a gas inlet to a gas outlet, including directing gas through one or more separators of a modular separator assembly and through one or more filter elements of a modular filter assembly to remove particulates from the gas;
- terminating the flow of gas through the pressure vessel;
- removing the modular separator assembly as an integral unit from the pressure vessel through an opening in the first axial end of the pressure vessel, wherein removing the modular separator assembly includes rolling the modular separator assembly along the interior of the pressure vessel on a plurality of wheels;
- installing one of a cleaned modular separator assembly and a new modular separator assembly as an integral unit into the pressure vessel through the opening in the first axial end of the pressure vessel, wherein installing the cleaned or new modular separator assembly includes rolling the cleaned or new modular separator assembly along the interior of the pressure vessel on a plurality of wheels;
- and
- restablishing a flow of gas through the interior of the pressure vessel from the gas inlet to the gas outlet and through the cleaned or new modular separator assembly in the interior of the pressure vessel.
