Embodiment
The application is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining related invention, rather than the restriction to the invention.It also should be noted that, in order to
It is easy to illustrate only the part related to invention in description, accompanying drawing.
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase
Mutually combination.Describe the application in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
Fig. 1 is refer to, the embodiment of the present invention provides a kind of FPSO flared gases recovery system control method, including step：
S1：The gas pressure in pressure sensor detection torch point flow container in torch point flow container, controller connects
Receive the detected value of pressure sensor；
S2：Compare whether the detected value is not more than the first setting value, if so, controller control first switch valve is beaten
Open, gas recovery system is started working, second switch valve is remained closed；Otherwise the controller control second switch valve is opened,
Flare tip carries out gas burning, and first switch valve is remained closed, and gas recovery system is stopped.
Gas of the FPSO flared gases recovery system control method provided in an embodiment of the present invention in torch point flow container
Gas is reclaimed or is delivered to flare tip and burnt by pressure selection, is illustrated in figure 2 FPSO flared gases recovery systems
Structural representation, is respectively connecting to gas recovery system and flare tip, respectively by two by two-way pipeline by torch point flow container
Switch valve is controlled, and the pressure in torch point flow container 1 is in normal condition, i.e. the pressure value of pressure sensor detection is not more than
First setting value, first switch valve 2 is opened, and second switch valve 5 is remained off, and the pipeline for being connected to gas recovery system is led
It is logical that gas is recycled in natural gas process processing system；If being in an emergency, it is necessary to which the gas flow being vented is than larger, torch
Pressure in point flow container 1 is gradually increasing, and when more than the setting value being the first setting value, second switch valve 5 is opened, first switch valve
2 remain off, and the pipeline conducting for being connected to flare tip 7 delivers gas to flare tip 7 and burnt.
Controller in the present invention is also used for storing the status information of first switch valve and second switch valve, is believed by state
Breath characterizes the state of each switch valve to open or closing, when the detected value that controller receives pressure sensor becomes
Change, corresponding control first switch valve and second switch valve are opened or are kept closed from closure state.
Further, including：Compare whether the detected value is more than the second setting value, if so, controller control the
Two switch valves are opened, and first switch valve is closed in preset time, are isolated the gas being connected with the first switch valve and are reclaimed system
System.
When there is urgent situation, the pressure of torch point flow container is persistently raised, and the pressure value of pressure sensor detection is more than
Second setting value, now system pressure already exceed tolerance range, controller opens rapidly second switch valve 5, and certain
The security that the separation gas retracting device of first switch valve 2 ensures system is closed in time.
The present embodiment the first setting value above-mentioned is that gas recovery system and flare tip carry out the critical of gas burning
Value, when less than or equal to the first setting value, gas recovery system can normal work, when more than the first setting value, this
Gas pressure in Shi Huoju point flow containers is larger, and gas recovery system has little time work, it is necessary to which that flare tip is lighted into progress is unnecessary
The burning of gas, and first switch valve and second switch valve are interlocking shapes, and one of to open, another is in certain time
Inside be bound to control closing；Second setting value is that the pressure that in emergency circumstances torch divides in flow container persistently rises to the value or big
When the setting value, flare tip lights progress gas burning and closes gas recovery system within a certain period of time.
Further, including：During the rupture disk explosion, controller control second switch valve is opened, when default
It is interior to close first switch valve, isolate the gas recovery system being connected with the first switch valve.
In order to further ensure that the safety of flare system itself, a side is set on the pipeline in parallel of second switch valve 5
Logical rupture disk 4, when second switch valve 5, which breaks down, to be opened in time, gas pressure can pop rupture disk 4, pass through
The pipeline of the bypass delivers the gas to flare tip 7 and burnt.
When the very fast system of pressure rise of torch point flow container 1 has little time reaction, the explosion of rupture disk 4, controller is simultaneously fast
Speed opens second switch valve 5, and closes the peace that the separation gas retracting device of first switch valve 2 ensures system within a certain period of time
Quan Xing, is emitted into flare tip by gas by second switch valve 5 and rupture disk 4 and burns, it is ensured that the in emergency circumstances burning of torch
And the security of process system.
Further, when the controller 15 controls the opening of second switch valve 5, while triggering is arranged on flare tip
Igniter 6.
When the control second switch of controller 15 valve 5 is opened, lighted a fire while triggering igniter 6, it is ensured that emptying gas are in fire
Torch head burns；And the opening of second switch valve 5 or the explosion of rupture disk 4 can all trigger igniter 6 and light a fire.
Further, if the controller is controlled before the first switch valve opening, second switch valve is open mode,
Then, the controller controls the first switch valve to open, and closes in preset time the second switch valve.
Further, if the controller is controlled before the second switch valve opening, the first switch valve is open shape
State,
Then, the controller controls the second switch valve to open, and closes in preset time the first switch valve.
First switch valve 2 and 5, second switch valve in FPSO flared gases recovery system provided in an embodiment of the present invention
One can be opened, when one of opening, another is necessary for closed mode, it is ensured that the security of system, and is opened at two
The time for closing valve progress either on or off switching is shorter, and another switch valve is must shut off within the default time, works as flare tip
When being burnt to gas, it is necessary to separate gas withdrawal line, when recovering gas take-back model, it is necessary to stop flare tip to gas
The burning of body.
Further, the preset time is 3s pulse signals.The time-switching of 3s pulse signals is set in the present embodiment
The on off state of first switch valve 2 and second switch valve 5, is effectively ensured system safety.
The embodiment of the present invention also provides FPSO flared gases recovery systems, including the torch being connected with torch header 14 point liquid
Tank 1, the torch point flow container 1 is connected to gas recovery system by first switch valve 2, and fire is connected to by second switch valve 5
Torch first 7；
