English Abstract

A production tank having a tank enclosure defined by a roof, a floor and a sidewall, one or more fluid inlets and one or more fluid outlets in fluid communication with the tank enclosure, and a fluid container for receiving overflow fluids. A pressure- relief riser has a first end in fluid communication with the fluid container and a second end positioned below the roof and above the one or more fluid outlets, the second end being in fluid communication with the tank enclosure. A frangible seal seals the pressure-relief riser that breaks upon application of a predetermined pressure.


French Abstract

Un réservoir de production ayant une enceinte de réservoir définie par un toit, un plancher, un mur latéral, au moins une entrée de fluide et au moins une sortie de fluide en communication fluide avec l'enceinte de réservoir, et un récipient de fluide pour recevoir le surplus de fluides. Une colonne montante de dépression munie d'une première extrémité en communication fluide avec le récipient de fluide et une deuxième extrémité placée sous le toit et au-dessus la ou les sorties de fluide, la deuxième extrémité étant en communication fluide avec l'enceinte de réservoir. Un sceau frangible scelle la colonne montante de dépression qui brise lors de l'application d'une pression prédéterminée.

What is Claimed is:
1. A production tank, comprising:
a tank enclosure defined by a roof, a floor and a sidewall;
one or more fluid inlets in fluid communication with the tank enclosure;
one or more fluid outlets in fluid communication with the tank enclosure;
a fluid container for receiving overflow fluids;
a pressure-relief riser having a first end in fluid communication with the
fluid
container and a second end positioned below the roof and above the one or more
fluid outlets,
the second end being in fluid communication with the tank enclosure; and
a frangible seal that seals the pressure-relief riser, the frangible seal
breaking upon
application of a predetermined pressure.
2. The production tank of claim 1, wherein the frangible seal is positioned
toward the
first end of the pressure-relief riser.
3. The production tank of claim 1, wherein:
the fluid container is recessed within the sidewall and is separate from the
tank
enclosure; and
the first end of the pressure-relief riser is positioned within the tank
enclosure.
4. The production tank of claim 1, wherein the fluid container is outside
the tank
enclosure.
5. The production tank of claim 4, wherein the fluid container is a
collapsible container.
6. The production tank of claim 1, wherein the one or more fluid outlets
comprise a
plurality of outlet risers that extend to a plurality of outlet heights within
the tank enclosure,
the second end of the pressure-relief riser being above the highest of the
plurality of outlet
heights.
7. A method of relieving pressure in a production tank comprising a tank
enclosure

11

defined by a roof, a floor, and a sidewall, the production tank further
comprising one or more
fluid inlets in fluid communication with the tank enclosure and one or more
fluid outlets in
fluid communication with the tank enclosure, the method comprising the steps
of:
mounting a pressure-relief riser to the production tank, the pressure-relief
riser having
a first end in fluid communication with a fluid container and a second end
positioned below
the roof and above the one or more fluid outlets of the production tank, the
second end being
in fluid communication with the tank enclosure;
attaching a frangible seal to seal the pressure-relief riser, the frangible
seal being
designed to break upon application of a predetermined pressure; and
filling the production tank with production fluids.
8. The method of claim 7, further comprising the steps of:
permitting fluids to enter pressure relief riser, the fluids breaking the
frangible seal to
break upon application of the predetermined pressure; and
collecting fluids within the fluid container.
9. The method of claim 7, wherein the predetermined pressure comprises at
least one of
a fluid pressure applied by fluid within the pressure-relief riser, a
pneumatic pressure within
the tank enclosure and a vacuum pressure within the tank enclosure.
10. The method of claim 7, wherein the frangible seal is positioned toward
the first end of
the pressure-relief riser.
11. The method of claim 7, wherein:
the fluid container is recessed within the sidewall and is separate from the
tank
enclosure; and
the first end of the pressure-relief riser is positioned within the tank
enclosure.
12. The method of claim 7, wherein the fluid container is outside the tank
enclosure.
13. The method of claim 12, wherein the fluid container is a collapsible
container.

12

14. The method of
claim 7, wherein the one or more fluid outlets comprise a plurality of
outlet risers that extend to a plurality of outlet heights within the tank
enclosure, the second
end of the pressure-relief riser being above the highest of the plurality of
outlet heights.
