English Abstract

A production tank has a tank enclosure defined by a roof, a floor and a sidewall, at least one fluid inlet in fluid communication with the tank enclosure, and at least one fluid outlet in fluid communication with the tank enclosure. The at least one fluid outlet has a primary valve and a secondary valve with first and second actuators. The second actuator is biased toward a closed position. A fluid container is disposed below the at least one fluid outlet. A controller is connected to the at least one secondary valve and maintains the at least one secondary valve in an open position when activated. The controller permits the at least one secondary valve to close when deactivated. A sensor in communication with the fluid container is configured to deactivate the controller when a predetermined fluid condition is sensed.


French Abstract

Un réservoir de production comprend une enceinte définie par un toit, un plancher et une paroi latérale, et est muni d'au moins une entrée à fluide en communication fluidique avec l'enceinte du réservoir et d'au moins une sortie à fluide en communication fluidique avec l'enceinte du réservoir. La(les) sortie(s) à fluide comprend(comprennent) une vanne principale et une vanne secondaire munies d'un premier et d'un second actionneur. Le second actionneur est réglé en position fermée. Un contenant à fluide est disposé sous la(les) sortie(s) à fluide. Une commande est connectée à la (aux) soupape(s) secondaire(s) et la(les) maintient en position ouverte lorsqu'elle est activée. La commande permet à la (aux) soupape(s) secondaire(s) de se fermer lorsqu'elle est désactivée. Un capteur en communication avec le contenant à fluide est configuré pour désactiver la commande lorsqu'une condition prédéterminée du fluide est détectée.

What is Claimed is:
1. A production tank, comprising:
a tank enclosure defined by a roof, a floor and a sidewall;
at least one fluid inlet in fluid communication with the tank enclosure;
at least one fluid outlet in fluid communication with the tank enclosure
comprising:
a primary valve that has a first actuator for opening and closing the primary
valve; and
a secondary valve in line with the primary valve, the secondary valve having a

second actuator for opening and closing the secondary valve, the second
actuator being biased
toward a closed position;
a fluid container disposed below the at least one fluid outlet;
a controller connected to the at least one secondary valve, the controller
maintaining
the at least one secondary valve in an open position when activated and the
controller
permitting the at least one secondary valve to move to the closed position
when deactivated;
and
a sensor in communication with the fluid container configured to deactivate
the
controller when a predetermined fluid condition is sensed within the fluid
container.
2. The production tank of claim 1, wherein the controller comprises a
pressurized gas in
fluid communication with the second actuator of the at least one secondary
valve, the
pressurized gas maintaining the at least one secondary valve in the open
position, and the
controller is deactivated by releasing the gas pressure against the second
actuator.
3. The production tank of claim 2, wherein the controller comprises an
electrical power
source, the at least one secondary valve comprises a solenoid valve, and the
controller is
deactivated by de-energizing the solenoid valve.
4. The production tank of claim 1, wherein the sensor comprises a float
that detects the
presence of liquid in the fluid container.
5. The production tank of claim 1, further comprising at least one
deactivation switch

outside the the production tank and spaced from the at least one fluid outlet.
6. The production tank of claim 1, wherein the fluid container comprises an
outlet
enclosure that encloses the at least one fluid outlets and is recessed within
the tank enclosure
relative to the sidewall.
7. A production tank, comprising:
a tank enclosure defined by a roof, a floor and a sidewall;
at least one fluid inlet in fluid communication with the tank enclosure;
at least one fluid outlet in fluid communication with the tank enclosure
comprising:
a primary valve that has a first actuator for opening and closing the primary
valve; and
a secondary valve in line with the primary valve, the secondary valve having a
second actuator for opening and closing the secondary valve;
a fluid container disposed below the at least one fluid outlet;
a control arm connected to the at least one secondary valve, the control arm
moving
between a raised closing position in which the at least one secondary valve is
closed and a
lowered opening position in which the at least one secondary valve is opened;
a float carried by the control arm and positioned within the fluid container,
the float
applying an upward force to the control arm when a predetermined level of
fluid is in the fluid
container such that the control arm closes the at least one secondary valve.
8. The production tank of claim 7, further comprising at least one
deactivation lever
connected to the at least one secondary valve and positioned outside the
production tank and
spaced from the at least one fluid outlet.
9. The production tank of claim 7, wherein the fluid container comprises an
outlet
enclosure that encloses the at least one fluid outlets and is recessed within
the tank enclosure
relative to the sidewall.
10. The production tank of claim 7, wherein the at least one secondary
valve is biased to
the closed position and is maintained in the open position until released by
the controller.
