Abstract
A fugitive emmissions accumulator having particular, although not exclusive, use in capturing fugitive oil at a wellhead, wherein an accumulator vessel is sealingly mounted to the wellhead about the polish rod, and wiper means disposed in the accumulator vessel to remove fugitive oil from the polish rod, and wherein the wiper means is floatable relative to the vessel so as to maintain wiping contact with the polish rod at all times, including vertical misalignment thereof.
Claims12
In a fugitive emission accumulator for use in collecting blow by at a wellhead, of the type having a stuffing box with a polish rod protruding from the top of the stuffing box and being reciprocable along an essentially vertical axis therethrough, comprising, in combination:
- a fluid accumulator vessel, said vessel disposed immediatly above, and in sealing relationship with the stuffing box;
- means defining an opening through said vessel, said opening adapted to surround the polish rod so as to permit reciprocal movement of the polish rod through said vessel;
- wiper means disposed about the polish rod within said vessel, said wiper means being in contact with said polish rod so as to wipe accumulated fluid collected on the surface of the polish rod as it reciprocates into and out of the stuffing box;
- said wiper means being mounted in said vessel, and being floatable with respect thereto so as to maintain wiping contact with the polish rod at all times, including times of axial misalignment, whereby fluid accumulation on the polish rod is wiped off and deposited in said vessel, thereby inhibiting escape thereof to the atmosphere.
