Abstract:
1. 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.
